Bentley was the son of Stanley Ackley and Ophelia A. Cogswell, husband of Bertha Myers, and brother of Alfred Ackley.
He learned the melodeon, piano, coronet, clarinet and piccolo as a boy. After moving to New York City in 1888, he began playing the organ in several churches.
In 1907, Bentley joined the Billy Sunday-Homer Rodeheaver evangelism team as secretary-pianist, and traveled with them for eight years.
As a composer and editor with the Rodeheaver Company, he wrote over 3,000 Gospel tunes.
