Karl Suessdorf, born 28 April 1921 - died 1982, Riverside, California, was a composer best known for his collaboration with lyricist John Blackburn in composing the jazz standard "Moonlight in Vermont", which was first recorded in 1943 by Billy Butterfield's Orchestra featuring Margaret Whiting. He also wrote "I Wish I Knew" and "Susquehanna" with Blackburn.
Suessdorf co-wrote "Christmas Madonna" and "Coral Sea" with lyrics by Nick Cea; "Key Largo" (sung by Marian McPartland) and "She Doesn't Laugh Like You" with Benny Carter and Leah Worth; and a 1949 hit for Perry Como, "Did Anyone Ever Tell You, Mrs. Murphy?", with lyrics by Leah Worth and Lloyd Sloan.
Apart from the many other performers who have recorded Suessdorf's compositions, including Billie Holiday and Frank Sinatra, Sarah Vaughan's compilation album Music of the Stars, Volume 2: Songs Recorded by Sarah Vaughan includes both "Key Largo" and "Moonlight in Vermont". "Moonlight in Vermont" is a popular song about the U.S. state of Vermont, written by John Blackburn and Karl Suessdorf and published in 1943.
The lyrics are very unusual for an American pop song of the 1940s, because they do not.
