Louis Katzman was a conductor, composer, session musician, and arranger in the first half of the twentieth century. He was born in Kishinev, Russian Empire (present day Chișinău, Moldova), and played in a number of Russian orchestras prior to his immigration to New York in 1907. While he initially found it difficult to find full-time work as a musician on his arrival in the United States, he eventually gained steadier employment as a musician and conductor with various bands and orchestras in the city, ultimately becoming involved in radio as well.

Katzman was a music director for various radio stations, including Brunswick Laboratories, and he was a key member in the inception of Broadcast Music, Incorporated (BMI). Katzman was also a conductor and music arranger for George Gershwin's radio program "Music By Gershwin" in the 1930s. Each episode of the program consisted of Gershwin's music, an interview with a guest composer, and a medley of the guest's hits. Other arrangers included Louis' son Henry Manners Katzman, Morton Gould, Cesare Sodero, Mark White, and Leith Stevens.

Following his work on Gershwin's radio program, Katzman became heavily involved with the production-arranging department at BMI and remained so until shortly before his death in 1943.

Henry Manners Katzman (1912-2001) was a composer, musician, and arranger from New York City. He worked with his father, Louis, as a rehearsal and orchestral pianist on "Music By Gershwin," later working on recordings directly with Gershwin. Katzman went on to become an arranger and manager at Broadcast Music, Incorporated. He died in San Francisco, California, on May 11, 2001.
