Samuel F. B. Morse
1791–1872 · Inventor and Painter
An American artist and inventor who helped develop a practical electromagnetic telegraph system and the signalling code that became known as Morse code.
“What hath God wrought?”
Why is this scientist famous?
Helped develop a practical single-wire electric telegraph and the signalling system known as Morse code, working with important collaborators including Alfred Vail and Leonard Gale.
Samuel's story
The Artist
Samuel Finley Breese Morse was born in Charlestown, Massachusetts, the son of a Calvinist preacher and geographer. He attended Yale College, where he studied mathematics and science alongside religious philosophy, but his passion was art. After graduating, he travelled to England to study painting at the Royal Academy. He spent four years in London, honing his skills as a portrait and historical painter, and exhibited at the Royal Academy. He returned to America in 1815 hoping to make his living as a fine artist, but America was not yet ready for grand historical painting. He scraped by as a portrait painter, travelling from town to town in search of commissions. He painted portraits of presidents and notable figures, but he always felt that his talents were underappreciated.
The Fateful Voyage
In 1832, while sailing from Europe back to America, Morse heard a shipboard discussion about electromagnetism that inspired his ideas for an electric telegraph. If an electric current could be sent through a long wire, it could carry messages at a speed no horse, ship, or pigeon could match. Morse was not the first to think of an electric telegraph, but he was determined to create a practical system. He returned to New York and, between painting commissions, began designing a device that could send coded messages over a wire.
Morse Code and the Telegraph
Morse was not the first person to develop an electric telegraph. His achievement was creating an influential practical system with important help from collaborators. Leonard Gale helped Morse apply advances in electromagnetism, and Alfred Vail helped develop and improve the equipment and signalling system. Their work produced the single-wire telegraph system that became closely associated with Morse's name. The system of dots and dashes that became known as Morse code developed during Morse's collaboration with Alfred Vail. Vail made important contributions to the practical telegraph system and its signalling methods. Morse demonstrated early versions of his telegraph in 1837 and 1838 and received a major U.S. patent for his telegraph in 1840.
What Hath God Wrought
After years of lobbying Congress, Morse finally secured funding to build a telegraph line from Washington, D.C. to Baltimore. On 24 May 1844, in a demonstration witnessed by members of Congress, Morse sat in the Supreme Court chamber of the U.S. Capitol and tapped out a message to his assistant Alfred Vail in Baltimore. The message — 'What hath God wrought?' — was suggested by Annie Ellsworth, the daughter of the commissioner of patents, and was taken from the Book of Numbers in the Bible. Vail received it and sent it back. The famous first public message sent over Morse's Washington-to-Baltimore telegraph line was a sensation. The telegraph spread across America and the world with astonishing speed, connecting cities, countries, and continents within a single generation.
A Mixed Legacy
Morse became famous and wealthy from telegraphy and spent years defending his patent claims. His life also included views that deserve to be remembered critically. He campaigned against Catholic immigration and supported slavery. These beliefs are an important and troubling part of his history, separate from the importance of his work on telegraphy. He died in New York in 1872.
Legacy
Electric telegraphy transformed long-distance communication during the nineteenth century. Morse's system became one of the most influential telegraph systems and helped establish the idea that information could be transmitted rapidly using electrical signals.
What did they discover?
The Electric Telegraph
Morse, working with collaborators including Alfred Vail and Leonard Gale, developed an influential practical single-wire electric telegraph system.
Morse Code
The signalling system that became known as Morse code developed during Morse's collaboration with Alfred Vail and used combinations of short and long signals to represent letters and numbers.
Washington–Baltimore Telegraph Demonstration
On 24 May 1844 Morse sent the famous message 'What hath God wrought?' from Washington, D.C., to Alfred Vail in Baltimore over the new telegraph line.
Amazing facts
Morse was a professional portrait painter before he became an inventor — he studied art at the Royal Academy in London and painted portraits of American presidents.
He was 41 years old when he first began working on the telegraph, inspired by a shipboard conversation about electromagnetism in 1832.
The famous first message — 'What hath God wrought?' — was suggested to Morse by Annie Ellsworth, the young daughter of the commissioner of patents.
In 1999, full implementation of the Global Maritime Distress and Safety System ended the international requirement for ships to maintain a Morse-code distress watch.
Morse spent years defending his patent claims. In O'Reilly v. Morse in 1854, the U.S. Supreme Court upheld some specific claims but rejected his broad eighth claim.
Morse demonstrated early versions of his telegraph in 1837 and 1838 and received a major U.S. patent for his telegraph in 1840.
Morse also held anti-Catholic, anti-immigration and pro-slavery views. These beliefs are an important and troubling part of his history.
