Born: February 6, 1844, Wales.
Died: June 12, 1911, New York City.
A converted Jew, Alman enlisted in the American navy in 1854 as an apprentice, and served until 1868. He was at the Washington Navy Yard when president Abraham Lincoln was shot.
He was one of the few men who knew of the final disposition of assassin John Wilkes Booth’s body, but he was sworn to secrecy.
After two years of service with the United States Government, he resigned and became an evangelist, taking charge of the mission that later became Emmanuel Baptist Church on Suffolk and Grand in Manhattan, New York.
He was ordained in the Fifth Avenue Baptist Church in 1871 and served as pastor of Emmanuel Baptist Church until 1899.
At one time he was commander-in-chief of the National Association of Naval Veterans, holding the title of Admiral. He was also chaplain of the Grand Army of the Republic, and the Farragut Association of Naval Veterans.
He is sometimes confused with Samuel Alman, the Russian-British composer (1877–1947).
