Jack Leonard "J.L." Warner (August 2, 1892 - September 9, 1978), born Jacob Warner in London, Ontario, Canada, was the president and driving force behind the successful development of Warner Brothers Studios in Hollywood, Los Angeles, California. At the time of his retirement, Warner's 45-year career was lengthier than that of any other Hollywood studio head. Thomas (1990), p. 4.

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. Thomas (1990), pp. 52-62. After Sam's death, Jack clashed with his surviving older brothers, Harry and Albert Warner. He assumed exclusive control of the film production company in the 1950s, when he secretly purchased his brothers' shares in the business after convincing them to participate in a joint sale of stocks. Thomas (1990), p. 226.

Although Warner was feared by many of his employees and inspired ridicule with his uneven attempts at humor, he earned respect for his shrewd instincts and toughmindedness. Thomas (1990), p. 4. He recruited many of Warner Bros.' top stars Thomas (1990), pp. 45-49. and promoted the hard-edged social dramas for which the studio became known. Buhle and Wagner (2002), p. 59. Given to quick decision making, Warner once commented, "If I'm right fifty-one percent of the time, I'm ahead of the game".

Throughout his career, he was viewed as a contradictory and enigmatic figure. Thomas (1990), pp. 4-7. Although he was a staunch Republican, Warner encouraged film projects that promoted the agenda of Democratic President Franklin D. Roosevelt's New Deal. He speedily grasped the threat posed by European fascism and criticized Nazi Germany well before America's involvement in World War II. Buhle and Wagner (2002), p. 68. During the postwar era, however, Warner supported an anti-Communist crusade that culminated in the "blacklisting" of Hollywood directors, actors, screenwriters, and technicians. Buhle and Wagner (2002), pp. 377-378. Despite his controversial public image, Warner remained a force in the motion picture industry until his retirement in the early 1970s. Thomas (1990), p. 3.

Jack Warner OBE (October 24, 1896 - May 24, 1981) was a popular British film and television actor.

He was born in London, his real name being Horace John Waters. Warner (1975), p. 2. His sisters Elsie and Doris Waters were well-known comediennes under the names Gert and Daisy. Warner (1975), pp. 74-75. Like them, Jack Warner made his name in music hall and radio, but he became known to cinema audiences as the patriarch in a trio of popular post-World War II family films beginning with Here Come the Huggetts. He also co-starred in the 1955 Hammer film version of The Quatermass Xperiment and as a police superintendent in the 1955 Ealing Studios black comedy The Ladykillers.

Warner attended the Coopers' Company's Grammar School for boys in Mile End, Warner (1975), p. 10. while his sisters both attended the nearby sister school, Coborn School for Girls in Bow. The three children were choristers at St. Leonard's Church, Bromley-by-Bow, and for a time, Warner was the choir's soloist.

It was in 1949 that Warner first played the role with which he would forever after be associated, that of PC George Dixon in the film, The Blue Lamp. Warner (1975), p. 108. One observer predicted, "This film will make Jack the most famous policeman in Britain". Although the police constable was shot dead in the film, the character was later revived for the long-running BBC television series, Dixon of Dock Green, which debuted in 1955 and ran until 1976, although in later years the aged Warner and his long-past-retirement-age character were confined to a less prominent desk Sergeant role. The series had a prime-time slot on Saturday evenings, and always opened with PC Dixon giving a little soliloquy to the camera, beginning with the words, "Good evening, all". According to Warner's autobiography, Jack of All Trades, Elizabeth II once visited the television studio where the series was filmed and told Warner "that she thought Dixon of Dock Green had become part of the British way of life". Warner (1975), p. 84.

He was appointed an Officer of the Order of the British Empire (OBE) in 1965. Warner (1975), p. 201.

The characterisation by Warner of Sergeant George Dixon, was held in such high regard that officers from Paddington Green Police Station bore the coffin at his funeral in 1981. Sydney-Smith (2002), pp. 105-106.
