Back to Sid's filmography: This film records the life of Eli Simpson (1884-1962), and the major contribution he made to British caving. He founded the British Speleological Association in 1935, and although nominally its Honorary Recorder, dominated its activities. His controversial approach to the original explorations of Lancaster Hole in the post-war years, whilst motivated by speleological and conservation interests, only succeeded in fragmenting the association. The film features interviews with Harry Long, Bob Leakey, Dave Judson, Bertie Bradshaw, Frank Atkinson, and "Potts" Barker, all of whom worked with Cymmie.
