Leonard DePaur (1914-1988) was a celebrated choral conductor and arranger whose work shaped American choral music throughout the mid-20th century. He founded the DePaur Infantry Chorus during World War II, which became one of the most recorded and performed military choirs of its era, and he later guest-conducted major orchestras and choral ensembles across the United States.
DePaur's arrangements are known for their accessibility, humor, and ability to bring out the musicality in both simple and complex material. His gift for writing for men's voices in particular made him a go-to arranger for TTBB repertoire, and his pieces remain staples in high school and college choir libraries.
