John Adrian Shepherd-Barron was born on June 23, 1925 at Shillong (now Meghalaya) in the Indian province of Assam, India to British parents. His Scottish father, Wilfred Barron, was chief engineer of the Chittagong Port Commissioners East Bengal (now Bangladesh) which was then part of the British Empire then later Chief Engineer of the Port of London Authority before becoming president of the Institute of Civil Engineers, whilst his mother Dorothy, was an Olympic tennis player and Wimbledon ladies doubles champion.[2] Shepherd-Barron was educated at Stowe School, the University of Edinburgh and Trinity College, Cambridge. During World War II, he was commissioned into the Airborne Forces, serving with the 159th Parachute Light Regiment.[2]
Shepherd-Barron joined De La Rue Instruments in the 1960s and came up with the concept of a self-service machine which would dispense paper currency with 24/7 availability. This was the Automated Teller Machine (ATM).[3] The first machine was established outside an Enfield, north London, branch of Barclays Bank in June 1967,[3] when he was Managing Director of De La Rue Instruments. According to the ATM Industry Association, there are now more than 1.7 million installed worldwide.[4] He received the Order of the British Empire in the 2005 New Year's Honours list for services to banking as "inventor of the automatic cash dispenser". Shepherd-Barron told the BBC that he was inspired by chocolate vending machines.
There is still some controversy over the invention. James Goodfellow developed an alternative ATM design, using PIN technology (which he invented), resembling modern ATMs more than Shepherd-Barron's machine.[5] However, Shepherd-Barron's machine (the idea for which he had in the bath, after having been locked out of his bank)[6][7] was the first to be installed.
The Shepherd-Barron dispenser actually predated the introduction of the plastic card with its magnetic strip: the machines used special cheques which had been impregnated with a radioactive compound of carbon-14, which was detected and matched against the personal identification number (PIN) entered on a keypad. A proposed PIN length of 6 digits was rejected and 4 digits chosen instead, because it was the longest string of numbers that his wife could remember.[3]
As well as the ATM, he has also invented some less successful devices, such as one that plays the sound of a killer whale to deter seals from salmon farms.[3]
His son, Nicholas Shepherd-Barron FRS, is professor of algebraic geometry at the University of Cambridge.
He died on 15 May 2010 after a brief illness at the age of 84 in Raigmore Hospital, Inverness, Scotland.[1][8]
