Richard Ellsasser (September 14, 1926 - August 9, 1972) was an American concert organist, composer, and conductor who was primarily active during the 1940s to 1960s.
At the age of seven, he toured the eastern United States as an organist with various symphony orchestras.
During the 1960s, Ellsasser became a faculty member at the National Music Camp in Interlochen, Michigan.
He continued to conduct workshops, accompany musicals and perform in a few concerts during the last year of his life.
Ellsasser "freely arranged for the modern organ" a lively Rondo in G that he attributed to John Bull centuries earlier.
The Rondo is "not known to have existed at all" before Ellsasser published his arrangement in 1951, and he is generally presumed to have been the composer.
