Jonas Mekas (born December 23, 1922 at Semeniškiai village, near Biržai) is a Lithuanian filmmaker, writer, and curator who has often been called "the godfather of American avant-garde cinema." He was the founder of the Anthology Film Archives, The Film Makers Cooperative and Film Culture magazine. He wrote film reviews for Village Voice since 1958. He was heavily involved with artists such as Andy Warhol, Nico, Yoko Ono, John Lennon, Salvador Dalí and fellow Lithuanian George Maciunas.
Though his narrative films and documentaries are still highly regarded, he is best known for his diary films, such as Walden (1969), Lost, Lost, Lost (1975), Reminiscences of a Voyage to Lithuania (1972), and Zefiro Torna (1992). In 2001, he released a five-hour long diary film entitled As I Was Moving Ahead, Occasionally I Saw Brief Glimpses of Beauty, assembled by hand from an archive of fifty years worth of recordings of his life. Beginning in the Fall of 2006, Mekas plans to film 365 short videos for Apple's Video iPod, releasing one a day on his website.
Peter Sempel filmed Jonas Mekas in a film "Jonas in the desert" (1994).
