George Rosenkrans (Jan 17, 1881-Aug. 18, 1955) was an American composer of concert band music born in Penfield, Pennsylvania on January 17, 1881. His father was the music director of the local Methodist church, and George sang with the choir and learned to play the organ there. His first compositions included organ music and hymns. He also played the baritone horn in the town band, and eventually became the conductor. He composed his first march at age 17, and was soon turning out up to eight new marches each year. As interest in his music declined, he would sell new arrangements for as little as 50 cents, or give compositions away outright. In later life, he composed many works, including the "Grampian March", for the Grampian Band in nearby Grampian, Pennsylvania, his favorite group. He missed a 1948 tribute by the Navy Band because he felt he had no suitable clothes. He died in poverty in Penfield on August 18, 1955.

His music was well-thought-of. His march "Triumphant Battalions" was played at the liberation of Paris, and his dirge "Immortal Heroes" was played at the funerals of Franklin Roosevelt and Winston Churchill.
