Early life. Samuel Finley Breese Morse was born in Charlestown, Massachusetts, on April 27, 1791. He was the first son of Jedidiah Morse, a clergyman, and Elizabeth Breese, of New Jersey.
However, it was Samuel Morse (1791-1872) that successfully exploited the electromagnet and bettered Joseph Henry's invention. Morse made sketches of a  magnetized magnet  based on Henry's work. Morse invented a telegraph system that was a practical and commercial success.
