John Adrian Shepherd-Barron, (23 June 1925 – 15 May 2010) was a British inventor, who pioneered the development of the cash machine, sometimes referred to as the Automated Teller Machine or ATM.
Barron was born on 23 June 1925 at Shillong, then in the British Raj province of Assam (now in Meghalaya), to British parents.
Shepherd-Barron once explained that he came up with the idea of cash dispensers in 1965 while lying in his bath after finding his bank closed. It was then his habit to withdraw money on a Saturday, but on this particular weekend he had arrived one minute late and found the bank doors locked against him.
Later that year, he bumped into the chief general manager of Barclays Bank who was about to have lunch. Over a pink gin, Shepherd-Barron asked him for 90 seconds to pitch his idea for a cash machine.
Barclays commissioned Shepherd-Barron to build six cash dispensers, the first of which was installed at a branch in the north London suburb of Enfield on June 27 1967.
He invented some other less-well-known devices, including one which played the sound of a killer whale in an attempt to deter seals from salmon farms. When he retired to Scotland in 1985, when he was 60, he tried his hand at snail farming.
