Frank Henry Loesser (June 29, 1910, New York City – July 26, 1969, New York City) was an American composer and lyricist. He died of lung cancer at age 59.

During World War II, he wrote 1942’s “Praise the Lord and Pass the Ammunition”. Formerly a successful lyricist in collaboration with other composers, this was the first song for which Loesser composed the melody in addition to the lyric.

Loesser was awarded a Grammy Award in 1961 for Best Original Cast Show Album for How To Succeed In Business Without Really Trying.
