Samuel Finley Breese Morse (April 27, – April 2, ) was an American inventor and painter.
After having established his reputation as a portrait painter, in his middle age Morse contributed to the invention of a single-wire telegraph system based on European telegraphs. He was a co-developer of Morse code and helped to develop the commercial use of telegraphy.
Personal life

Samuel F. B. Morse was born in Charlestown, Massachusetts, the first child of the pastor Jedidiah Morse (–), who was also a geographer, and his wife Elizabeth Ann Finley Breese (–).
His father was a great preacher of the Calvinist faith and supporter of the Federalist Party. He thought it helped preserve Puritan traditions (strict observance of Sabbath, among other things), and believed in the Federalist support of an alliance with Britain and a strong central government. Morse strongly believed in education within a Federalist framework, alongside the instillation of Calvinist virtues, morals, and prayers for his first son.
His first ancestor in America was Anthony Morse, of Marlborough, in Wiltshire, who had emigrated to America in , and settled in Newbury, Massachusetts.
After attending Phillips Academy in Andover, Massachusetts, Samuel Morse went on to Yale College to study religious philosophy, mathematics, and science. While at Yale, he attended lectures on electricity from Benjamin Silliman and Jeremiah Day and was a member of the Society of Brothers in Unity.
He supported himself by painting. In , he graduated from Yale with Phi Beta Kappa honors.
Morse married Lucretia Pickering Walker on September 29, , in Concord, New Hampshire. She died on February 7, , of a heart attack shortly after the birth of their third child.
(Susan b. , Charles b. , James b. ). He married his second wife, Sarah Elizabeth Griswold on August 10, , in Utica, New York and had four children (Samuel b. , Cornelia b. , William b. , Edward b. ).
Painting
Morse expressed some of his Calvinist beliefs in his painting, Landing of the Pilgrims, through the depiction of simple clothing as well as the people's austere facial features.
His image captured the psychology of the Federalists; Calvinists from England brought to North America ideas of religion and government, thus linking the two countries. This work attracted the attention of the notable artist, Washington Allston. Allston wanted Morse to accompany him to England to meet the artist Benjamin West.
Allston arranged—with Morse's father—a three-year stay for painting study in England. The two men set sail aboard the Libya on July 15,
In England, Morse perfected his painting techniques under Allston's watchful eye; by the end of , he gained admittance to the Royal Academy. At the academy, he was moved by the art of the Renaissance and paid close attention to the works of Michelangelo and Raphael.
After observing and practicing life drawing and absorbing its anatomical demands, the young artist produced his masterpiece, the Dying Hercules. (He first made a sculpture as a study for the painting.)
To some, the Dying Hercules seemed to represent a political statement against the British and also the American Federalists.
The muscles symbolized the strength of the young and vibrant United States versus the British and British-American supporters. During Morse's time in Britain, the Americans and British were engaged in the War of Both societies were conflicted over loyalties. Anti-Federalist Americans aligned themselves with the French, abhorred the British, and believed a strong central government to be inherently dangerous to democracy.
As the war raged on, Morse's letters to his parents became more anti-Federalist in tone.

Although Jedidiah Morse did not change Samuel's political views, he continued as an influence. Critics believe that the elder Morse's Calvinist ideas are integral to Morse's Judgment of Jupiter, another significant work completed in England. Jupiter is shown in a cloud, accompanied by his eagle, with his hand spread above the parties and he is pronouncing judgment.
Marpessa, with an expression of compunction and shame, is throwing herself into the arms of her husband. Idas, who tenderly loved Marpessa, is eagerly rushing forward to receive her while Apollo stares with surprise.
Critics have suggested that Jupiter represents God's omnipotence—watching every move that is made. Many American paintings throughout the early nineteenth century had religious themes, and Morse was an early exemplar of this.
Judgment of Jupiter allowed Morse to express his support of Anti-Federalism while maintaining his strong spiritual convictions. Benjamin West sought to present the Jupiter at another Royal Academy exhibition, but Morse's time had run out. He left England on August 21, , to return to the United States and begin his full-time career as a painter.
The decade – marked significant growth in Morse's work, as he sought to capture the essence of America's culture and life.
He painted the Federalist former President John Adams (). The Federalists and Anti-Federalists clashed over Dartmouth College. Morse painted portraits of Francis Brown—the college's president—and Judge Woodward (), who was involved in bringing the Dartmouth case before the U.S. Supreme Court.
Morse also sought commissions among the elite of Charleston, South Carolina.
Morse's painting of Mrs. Emma Quash symbolized the opulence of Charleston. The young artist was doing well for himself. Between and , Morse went through great changes in his life, including a decline in commissions due to the Panic of
Morse was commissioned to paint President James Monroe in He embodied Jeffersonian democracy by favoring the common man over the aristocrat.
Morse had moved to New Haven.
His commissions for The House of Representatives () and a portrait of the Marquis de Lafayette () engaged his sense of democratic nationalism. The House of Representatives was designed to capitalize on the success of François Marius Granet's The Capuchin Chapel in Rome, which toured the United States extensively throughout the s, attracting audiences willing to pay the cent admission fee.
The artist chose to paint the House of Representatives, in a similar way, with careful attention to architecture and dramatic lighting.
He also wished to select a uniquely American topic that would bring glory to the young nation. His subject did just that, showing American democracy in action. He traveled to Washington D.C. to draw the architecture of the new Capitol and placed eighty individuals within the painting. He chose to portray a night scene, balancing the architecture of the Rotunda with the figures, and using lamplight to highlight the work.
Pairs of people, those who stood alone, individuals bent over their desks working, were each painted simply but with faces of character. Morse chose nighttime to convey that Congress' dedication to the principles of democracy transcended day.
The House of Representatives failed to draw a crowd when exhibited in New York City in By contrast, John Trumbull's Declaration of Independence had won popular acclaim a few years earlier.
Viewers may have felt that the architecture of The House of Representatives overshadows the individuals, making it hard to appreciate the drama of what was happening.
Morse was honored to paint the Marquis de Lafayette, the leading French supporter of the American Revolution.
He felt compelled to paint a grand portrait of the man who helped to establish a free and independent America. He features Lafayette against a magnificent sunset. He has positioned Lafayette to the right of three pedestals: one has a bust of Benjamin Franklin, another of George Washington, and the third seems reserved for Lafayette.
A peaceful woodland landscape below him symbolized American tranquility and prosperity as it approached the age of fifty. The developing friendship between Morse and Lafayette and their discussions of the Revolutionary War affected the artist after his return to New York City.
In , he helped found the National Academy of Design in New York City.
He served as the academy's president from to and again from to
From to , Morse traveled and studied in Europe to improve his painting skills, visiting Italy, Switzerland, and France. During his time in Paris, he developed a friendship with the writer James Fenimore Cooper. As a project, he painted miniature copies of 38 of the Louvre's famous paintings on a single canvas (6 ft.
x 9 ft), which he entitled The Gallery of the Louvre. He completed the work upon his return to the United States.
In , after his return to the United States, Morse was appointed professor of painting and sculpture at the University of the City of New York, now New York University.
On a subsequent visit to Paris in , Morse met Louis Daguerre.
He became interested in the latter's daguerreotype—the first practical means of photography. Morse wrote a letter to the New York Observer describing the invention, which was published widely in the American press and provided broad awareness of the new technology. Mathew Brady, one of the earliest photographers in American history, famous for his depictions of the Civil War, initially studied under Morse and later took photographs of him.
Some of Morse's paintings and sculptures are on display at his Locust Grove estate in Poughkeepsie, New York.

Telegraph
While returning by ship from Europe in , Morse encountered Charles Thomas Jackson of Boston, a man who was well schooled in electromagnetism.
Witnessing various experiments with Jackson's electromagnet, Morse developed the concept of a single-wire telegraph. He set aside his painting, The Gallery of the Louvre.

Samuel F.B. Morse was an American artist and inventor. Morse developed an electric telegraph. In the s, it was the fastest way to communicate over long distances. He also created Morse Code —the system of dots and dashes that were used to spell out messages over the telegraph.The original Morse telegraph, submitted with his patent application, is part of the collections of the National Museum of American History at the Smithsonian Institution. In time, the Morse code that he developed would become the primary language of telegraphy in the world. It is still the standard for rhythmic transmission of data.
Meanwhile, William Cooke and Professor Charles Wheatstone had learned of the Wilhelm Weber and Carl Gauss electromagnetic telegraph in They had reached the stage of launching a commercial telegraph prior to Morse, despite starting later.
In England, Cooke became fascinated by electrical telegraphy in , four years after Morse. Aided by his greater financial resources, Cooke abandoned his primary subject of anatomy and built a small electrical telegraph within three weeks. Wheatstone also was experimenting with telegraphy and (most importantly) understood that a single large battery would not carry a telegraphic signal over long distances.
He theorized that numerous small batteries were far more successful and efficient in this task. (Wheatstone was building on the primary research of Joseph Henry, an American physicist.) Cooke and Wheatstone formed a partnership and patented the electrical telegraph in May , and within a short time had provided the Great Western Railway with a mile (21 km) stretch of telegraph.
However, within a few years, Cooke and Wheatstone's multiple-wire signaling method would be overtaken by Morse's cheaper method.
In an letter to a friend, Morse describes how vigorously he fought to be called the sole inventor of the electromagnetic telegraph despite the previous inventions.
Relays
Morse encountered the problem of getting a telegraphic signal to carry over more than a few hundred yards of wire.
See full list on kids.kiddle.co Morse's painting of Mrs. Emma Quash symbolized the opulence of Charleston. The young artist was doing well for himself. Between and , Morse went through great changes in his life, including a decline in commissions due to the Panic of Morse was commissioned to paint President James Monroe in He embodied Jeffersonian.His breakthrough came from the insights of Professor Leonard Gale, who taught chemistry at New York University (he was a personal friend of Joseph Henry). With Gale's help, Morse introduced extra circuits or relays at frequent intervals and was soon able to send a message through ten miles (16 km) of wire. This was the great breakthrough he had been seeking.
Morse and Gale were soon joined by Alfred Vail, an enthusiastic young man with excellent skills, insights, and money.
At the Speedwell Ironworks in Morristown, New Jersey on January 11, , Morse and Vail made the first public demonstration of the electric telegraph. Although Morse and Alfred Vail had done most of the research and development in the ironworks facilities, they chose a nearby factory house as the demonstration site.
Without the repeater, Morse devised a system of electromagnetic relays. This was the key innovation, as it freed the technology from being limited by distance in sending messages. The range of the telegraph was limited to two miles ( km), and the inventors had pulled two miles ( km) of wires inside the factory house through an elaborate scheme.
The first public transmission, with the message, "A patient waiter is no loser", was witnessed by a mostly local crowd.
Morse traveled to Washington, D.C. in seeking federal sponsorship for a telegraph line but was not successful. He went to Europe, seeking both sponsorship and patents, but in London discovered that Cooke and Wheatstone had already established priority.
After his return to the US, Morse finally gained financial backing by Maine congressman Francis Ormand Jonathan Smith. This funding may be the first instance of government support to a private researcher, especially funding for applied (as opposed to basic or theoretical) research.
Federal support
Morse made his last trip to Washington, D.C., in December , stringing "wires between two committee rooms in the Capitol, and sent messages back and forth" to demonstrate his telegraph system.
Congress appropriated $30, (equivalent to $, in ) in for construction of an experimental mile (61 km) telegraph line between Washington, D.C., and Baltimore along the right-of-way of the Baltimore and Ohio Railroad. An impressive demonstration occurred on May 1, , when news of the Whig Party's nomination of Henry Clay for U.S. president was telegraphed from the party's convention in Baltimore to the Capitol Building in Washington.
On May 24, , the line was officially opened as Morse sent the now-famous words, "What hath God wrought," from the Supreme Court chamber in the basement of the U.S.
Capitol building in Washington, D.C., to the B&O's Mount Clare Station in Baltimore. Annie Ellsworth chose these words from the Bible (Numbers ); her father, U.S. Patent Commissioner Henry Leavitt Ellsworth, had championed Morse's invention and secured early funding for it. His telegraph could transmit thirty characters per minute.
In May , the Magnetic Telegraph Company was formed in order to build telegraph lines from New York City toward Philadelphia; Boston; Buffalo, New York; and the Mississippi.
Telegraphic lines rapidly spread throughout the United States in the next few years, with 12, miles of wire laid by
Morse at one time adopted Wheatstone and Carl August von Steinheil's idea of broadcasting an electrical telegraph signal through a body of water or down steel railroad tracks or anything conductive. He went to great lengths to win a lawsuit for the right to be called "inventor of the telegraph" and promoted himself as being an inventor.
But Alfred Vail also played an important role in the development of the Morse code, which was based on earlier codes for the electromagnetic telegraph.
Patent
Morse received a patent for the telegraph in , at the old Beylerbeyi Palace (the present Beylerbeyi Palace was built in – on the same location) in Istanbul, which was issued by Sultan Abdülmecid, who personally tested the new invention.
He was elected an Associate Fellow of the American Academy of Arts and Sciences in The original patent went to the Breese side of the family after the death of Samuel Morse.
In , Morse went to Copenhagen and visited the Thorvaldsens Museum, where the sculptor's grave is in the inner courtyard. He was received by King Frederick VII, who decorated him with the Order of the Dannebrog for the telegraph.
Morse expressed his wish to donate his Thorvaldsen portrait from in Rome to the king. The Thorvaldsen portrait today belongs to Margrethe II of Denmark.
The Morse telegraphic apparatus was officially adopted as the standard for European telegraphy in Only the United Kingdom (with its extensive overseas empire) kept the needle telegraph of Cooke and Wheatstone.
In , Morse introduced wired communication to Latin America when he established a telegraph system in Puerto Rico, then a Spanish Colony.
Morse's oldest daughter, Susan Walker Morse (–), would often visit her uncle Charles Pickering Walker, who owned the Hacienda Concordia in the town of Guayama. During one of her visits, she met Edward Lind, a Danish merchant who worked in his brother-in-law's Hacienda La Henriqueta in the town of Arroyo.
Videos Samuel Finley Breese Morse was born on April 27, He was the eldest son of Jedidiah Morse, a noted Congregational minister, and Elizabeth Ann Breese Morse. He was educated at Phillips Academy, in Andover, and at Yale University. While he was in college he became interested in electricity, but his chief enthusiasm was art.They later married. Lind purchased the Hacienda from his sister when she became a widow. Morse, who often spent his winters at the Hacienda with his daughter and son-in-law, set a two-mile telegraph line connecting his son-in-law's Hacienda to their house in Arroyo. The line was inaugurated on March 1, , in a ceremony flanked by the Spanish and American flags.
Political views
Morse, edition
Anti-Catholic
Morse was a leader in the anti-Catholic and anti-immigration movement of the midth century. In , he ran unsuccessfully for mayor of New York under the anti-immigrant Nativist Party's banner, receiving only 1, votes. When Morse visited Rome, he allegedly refused to take his hat off in the presence of the Pope.
Morse worked to unite Protestants against Catholic institutions (including schools), wanted to forbid Catholics from holding public office, and promoted changing immigration laws to limit immigration from Catholic countries.
On this topic, he wrote, "We must first stop the leak in the ship through which muddy waters from without threaten to sink us."
He wrote numerous letters to the New York Observer (his brother Sidney was the editor at the time) urging people to fight the perceived Catholic menace. These were widely reprinted in other newspapers. Among other claims, he believed that the Austrian government and Catholic aid organizations were subsidizing Catholic immigration to the United States in order to gain control of the country.
In the same book, published in under the name of "Brutus", in speaking of "the foreign Emissaries of Popery re-warded in their own country," said : "Where is Bishop Kelly of Richmond, Va.?
He also sojourns with us until his duties to foreign masters are performed, and then is rewarded by promotion." (Patrick Kelly was a native of Ireland, and the first bishop of Richmond, Virginia. When after a couple of years, differences regarding questions of jurisdiction arose between him and Ambrose Maréchal, Archbishop of Baltimore, Kelly was offered the recently vacant See of Waterford and Lismore in his homeland.)
Pro-slavery
In the s, Morse became well known as a defender of slavery, considering it to be sanctioned by God.
Later years
Litigation over telegraph patent
In the United States, Morse held his telegraph patent for many years, but it was both ignored and contested.
In , The Telegraph Patent case – O'Reilly v. Morse came before the U.S. Supreme Court where, after very lengthy investigation, Chief JusticeRoger B. Taney ruled that Morse had been the first to combine the battery, electromagnetism, the electromagnet, and the correct battery configuration into a workable practical telegraph.
However, in spite of this clear ruling, Morse still received no official recognition from the United States government.
The Supreme Court did not accept all of Morse's claims. The O'Reilly v. Morse case has become widely known among patent lawyers because the Supreme Court explicitly denied Morse's claim 8 for any and all use of the electromagnetic force for purposes of transmitting intelligible signals to any distance.
The Supreme Court sustained, however, Morse's claim to such telecommunication when effectuated by means of Morse's inventive "repeater" apparatus.
This was an electrical circuit in which a cascade of many sets comprising a relay and a battery were connected in series, so that when each relay closed, it closed a circuit to cause the next battery to power the succeeding relay, as suggested in the accompanying figure. This caused Morse's signal to pass along the cascade without degrading into noise as its amplitude decreased with the distance traveled.
(Each time the amplitude of the signal approaches the noise level, the repeater [in effect, a nonlinear amplifier] boosts the signal amplitude well above the noise level.) This use of "repeaters" permitted a message to be sent to great distances, which was previously not feasible.
The Supreme Court thus held that Morse could properly claim a patent monopoly on the system or process of transmitting signals at any distance by means of the repeater circuitry indicated above, but he could not properly claim a monopoly over any and all uses of electromagnetic force to transmit signals.
The apparatus limitation in the former type of claim limited the patent monopoly to what Morse taught and gave the world. The lack of that limitation in the latter type of claim (i.e., claim 8) both gave Morse more than was commensurate with what he had contributed to society and discouraged the inventive efforts of others who might come up with different and/or better ways to send signals at a distance using the electromagnetic force.
The problem that Morse faced (the deterioration of the signal with distance) and how he solved it is discussed in more detail in the article O'Reilly v.

In the s, it was the fastest way to communicate over long distances. He also created Morse Code—the system of dots and dashes that were used to spell out messages over the telegraph.Morse. In summary, the solution, as the Supreme Court stated, was the repeater apparatus described in the preceding paragraphs.
The importance of this legal precedent in patent law cannot be overstated, as it became the foundation of the law governing the eligibility of computer program-implemented inventions (as well as inventions implementing natural laws) to be granted patents.
Foreign recognition

Assisted by the American ambassador in Paris, the governments of Europe were approached about their long neglect of Morse while their countries were using his invention. There was a widespread recognition that something must be done, and in Morse was awarded the sum of , French francs (equivalent to about $80, at the time) by the governments of France, Austria, Belgium, the Netherlands, Piedmont, Russia, Sweden, Tuscany, and the Ottoman Empire, each of which contributed a share according to the number of Morse instruments in use in each country.
In , he was also elected a foreign member of the Royal Swedish Academy of Sciences.
Transatlantic cable
Morse lent his support to Cyrus West Field's ambitious plan to construct the first transoceanic telegraph line. Morse had experimented with underwater telegraph circuits since He invested $10, in Field's Atlantic Telegraph Company, took a seat on its board of directors, and was appointed honorary "Electrician".
In , Morse traveled to London to help Charles Tilston Bright and Edward Whitehouse test a 2,mile-length of spooled cable.
After the first two cable-laying attempts failed, Field reorganized the project, removing Morse from direct involvement. Though the cable broke three times during the third attempt, it was successfully repaired, and the first transatlantic telegraph messages were sent in The cable failed after just three months of use.
Though Field had to wait out the Civil War, the cable laid in proved more durable, and the era of reliable transatlantic telegraph service had begun.
In addition to the telegraph, Morse invented a marble-cutting machine that could carve three-dimensionalsculptures in marble or stone. He could not patent it, however, because of an existing Thomas Blanchard design.
Last years and death
Samuel Morse gave large sums to charity.
He also became interested in the relationship of science and religion and provided the funds to establish a lectureship on "the relation of the Bible to the Sciences". Though he was rarely awarded any royalties for the later uses and implementations of his inventions, he was able to live comfortably.
Morsemere in Ridgefield, New Jersey takes its name from Morse, who had bought property there to build a home, but died before its completion.
He died in New York City on April 2, , and was interred at Green-Wood Cemetery in Brooklyn, New York.
By the time of his death, his estate was valued at some $, ($ million today).
Honors and awards
Morse was elected a member of the American Antiquarian Society in
Despite honors and financial awards received from foreign countries, there was no such recognition in the U.S. until he neared the end of his life when on June 10, , a bronze statue of Samuel Morse was unveiled in Central Park, New York City.
An engraved portrait of Morse appeared on the reverse side of the United States two-dollar bill silver certificate series of He was depicted along with Robert Fulton. An example can be seen on the website of the Federal Reserve Bank of San Francisco's website in their "American Currency Exhibit":
A blue plaque was erected to commemorate him at Cleveland Street, London, where he lived from to
In , Morse was elected as a member to the American Philosophical Society.
According to his The New York Times obituary published on April 3, , Morse received respectively the decoration of the Atiq Nishan-i-Iftikhar (English: Order of Glory) [first medal on wearer's right depicted in photo of Morse with medals], set in diamonds, from Sultan Abdülmecid of Turkey (c), a "golden snuff box containing the Prussian gold medal for scientific merit" from the King of Prussia (); the Great Gold Medal of Arts and Sciences from the King of Württemberg (); and the Great Golden Medal of Science and Arts from Emperor of Austria (); a cross of Chevalier in the Légion d'honneur from the Emperor of France; the Cross of a Knight of the Order of the Dannebrog from the King of Denmark (); the Cross of Knight Commander of the Order of Isabella the Catholic, from the Queen of Spain, besides being elected member of innumerable scientific and art societies in this [United States] and other countries.
Other awards include Order of the Tower and Sword from the kingdom of Portugal (), and Italy conferred on him the insignia of chevalier of the Order of Saints Maurice and Lazarus in Morse's telegraph was recognized as an IEEE Milestone in
In , Morse was inducted into the National Inventors Hall of Fame.
On April 1, , Google announced the release of "Gmail Tap", an April Fools' Day joke that allowed users to use Morse Code to send text from their mobile phones.
Morse's great-great-grandnephew Reed Morse—a Google engineer—was instrumental in the prank, which became a real product.
