Bert Lown, born Albert Charles Lown on June 6, 1903, in White Plains, New York, was an influential American violinist, orchestra leader, and songwriter. He began his musical career as a sideman in Fred Hamm's band, playing the violin. Lown gained prominence in the 1920s and 1930s by leading a series of jazz-oriented dance bands, most notably the Biltmore Hotel Orchestra. His bands were known for their superior performances, and he made numerous recordings during this period, particularly for Victor Records.

In 1925, Lown co-composed the jazz standard "Bye Bye Blues" with Fred Hamm, Dave Bennett, and Chauncey Gray. He also wrote other songs such as "You're The One I Care For" and "Tired." His orchestra's performances were frequently broadcast on the radio, and he recorded extensively for labels including Diva, Harmony, Velvet Tone, Columbia, and Bluebird.

By the mid-1930s, Lown transitioned from leading orchestras to becoming a booking agent and manager. Eventually, he left the music industry to pursue executive roles in the television sector, notably with CBS-TV. Lown was also involved in wartime fundraising and relief efforts during World War II. He passed away from a heart attack on November 20, 1962, in Portland, Oregon. His contributions to the music world, particularly his recordings and compositions, remain a significant part of his legacy.
