Frank Humphrey Sinkler Jennings (19 August 1907 – 24 September 1950) was an English documentary filmmaker, celebrated for his poetic and visually striking portrayals of British life during World War II. A co-founder of the Mass Observation social research organization, Jennings blended avant-garde techniques with a deep sense of national identity, creating films that captured the resilience and spirit of the British people. His most acclaimed works, including Listen to Britain (1942), Fires Were Started (1943), and A Diary for Timothy (1945), showcase his unique ability to fuse documentary realism with lyrical storytelling. Film critic and director Lindsay Anderson described him as "the only real poet that British cinema has yet produced."
