Art Jenson was known throughout the music industry for establishing Jenson Publishing in 1977. The company became one of the nation’s largest educational music publishers with a focus on band and choral works. In the mid '60's, Art did some writing for Charles Hansen Publications and in 1969, he joined the editorial staff of Zeb Billings Music Publishing. In 1970, Art along with Keith and Don Mardak started Learning Unlimited, which became a division of Hal Leonard Publishing Corp. They pioneered the print industry with several innovations including sending audio recordings of the music with each book. Art left in 1976 to start Jenson Publishing, which he eventually sold to Hal Leonard in 1989. Art stayed on with Hal Leonard and played a vital role in creating the Essential Elements Band series in which he took great pride. Art retired in 1991.
