 Pit caving was pioneered by the English geologist John Beaumont (c. 1650–1731) who gave an account of his descent into Lamb Leer Cavern to the Royal Society in 1681.French caver Édouard-Alfred Martel (1859–1938) first achieved the descent and exploration of the Gouffre de Padirac, France, as early as 1889 and the first complete descent of a wet vertical shaft at Gaping Gill, in Yorkshire, England, in 1895.He developed his own techniques using ropes and metallic ladders.
