John Marvin Chamberlain (May 27, 1844 – May 5, 1930[1]) was an English-born composer of Latter-day Saint hymns, a pianist and music store owner.
His parents were Latter-day Saints and in 1852 they left England to immigrate to Utah Territory.
They sailed to New Orleans, then went up-river to Florence, Nebraska, and then crossed the plains to Salt Lake City.
Chamberlain also served in the leadership of the Sunday School and as choir director in the 8th Ward in Salt Lake City.
In addition to "We Are Marching On to Glory" (originally titled "Marching Homeward"), Chamberlain wrote such hymns as "When Jesus Shall Come in His Glory" and "A Sunday School Call".
