Automated Teller Machine (ATM) is an indispensable part of our lives now worldwide!
John 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.
John 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. Shepherd-Barron asked him for 90 seconds to pitch his idea for a
cash machine.
“I told him I had an idea that if you put your standard Barclays cheque through a slot in
the side of the bank, it will deliver standard amounts of money around the clock.”
“He said, ‘Come and see me on Monday morning’.
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. The
first person to withdraw cash was actor Reg Varney, a celebrity resident of Enfield known
for his part in a number of popular television series. An early deployment of this device
outside of the UK took place in Zurich in November, 1967.
Shepherd-Barron was born at Shillong, India in 1925 to
British parents and later served in the Indian Army in Second
Airborne division where he taught Gurkhas to parachute. He
also invented the PIN by recalling his Indian Army number,
he had originally intended to make Personal Identification
Number (PIN) six digit long, but reduced the number to four
when his wife, Caroline, complained that six was too many.
“Over the kitchen table, she said she could only remember
four figures, so because of her, four figures became the world
standard,” he recalled.
All this was possible due to a mathematical prodigy by the name of Srinivasa Ramanujan
— A mathematical genius of India. When you put your debit or credit card in the machine
and order the machine to dispense the amount of your desire, the machine divides and
arranges your money before dispensing it, using Ramanujan’s ‘Partition Theory’.
