Alfred Vail (1807-1859) was born in Morristown, New Jersey, where his father was owner of the Speedwell Iron Works. After working in his father's shop and preparing for the Presbyterian ministry, Alfred became interested in Samuel F. B. Morse and his telegraph. In 1837 a contract was drawn between Vail and Morse whereby Vail would construct a complete set of instruments and secure U. S. and foreign patents for them at his expense, in return for one-fourth interest in the American rights and one-half interest in the patents secured abroad. Stephen and George Vail (Alfred's father and brother) invested. Alfred, Morse, and Leonard D. Gale worked in the Speedwell shops and on January 6, 1838, demonstrated the improved telegraph. Some sources give Alfred Vail the major credit for the perfection of the instruments. Congress did not purchase the telegraph as they had hoped, but Congressman Francis O. J. Smith became a partner with 4/16 interest; subsequently, friction developed between Smith and others in the telegraph enterprise. On the capital completed by Smith's contribution, Morse went to Europe to establish the enterprise there, and Alfred lost interest; from 1839-1843, Alfred conducted his father's business in Philadelphia. In 1843, when Congress passed the act to build the Washington-Baltimore line, Vail became Morse's chief assistant and stayed with Morse until 1845, but then was relieved from duty in Washington by Morse, and by 1848 resigned as superintendent in Philadelphia. In 1845, Alfred published The Electro Magnetic Telegraph and in 1849, The Register of the Electro Magnetic Telegraph Companies. After 1848, Vail's interest in the telegraph was mostly passive. He realized little money from his interest in the telegraph and died poor in 1859.
