Joseph was the son of Meyer Lerman and Eliza Maria Rush, and husband of Elizabeth Gibbon Snelling.
He emigrated to America as a child (he does not appear in the 1871 British census).
He was a member of the Olivet Memorial Church in New York City. He played the organ there (1880–1908), and later at the Sixth Avenue Baptist Church, Borough Park Christian Church, and Fourth Avenue Methodist Church, all in Brooklyn.
Lerman wrote a considerable amount of church and Sunday School music, and was musical editor for the Tullar-Meredith Company of New York City, and the Theodore Presser Company of Philadelphia, Pennsylvania.
If you know where to get a good photo of Lerman (head & shoulders, at least 200×300 pixels),
