Jack L. Warner Jack L. Warner Jack Leonard "J. L." Warner (August 2, 1892 – September 9, 1978), born Jacob Warner in London, Ontario, was a Jewish Canadian-American film executive who was the president and driving force behind the Warner Bros. Studios in Burbank, California. Warner's career spanned some 45 years, its duration surpassing that of any other of the seminal Hollywood studio moguls. As co-head of production at Warner Bros. Studios, he worked with his brother, Sam Warner, to procure the technology for the film industry's first talking picture. After Sam's death, Jack clashed with his surviving older brothers, Harry and Albert
The Albert Brothers Criteria and became an engineer alongside his brother. From here on out, the duo were known as "Fat Albert Productions." The Albert Brothers, along with Atlantic producers Tom Dowd and Arif Mardin, Atlantic co-owner Jerry Wexler, and equipment-designer Jeep Harned, helped Criteria become a heavily sought after recording studio. Eventually, the brothers became partners in the company. By 1983, however, Criteria was in debt and planning on retiring, the brothers sold their share in the company. In 1987, their plan of retirement was canceled and they created two new companies with their partner Steve Alaimo: Vision Records and Audio Vision
