Ever want to know the history behind the invention now known as the ATM. Check out this site.
In 1939, Luther Simjian patented an early and not-so-successful prototype of an ATM.
However, some experts have the opinion that James Goodfellow of Scotland
holds the earliest patent date of 1966 for a modern ATM, and John D
White (also of Docutel) in the US is often credited with inventing the
first free-standing ATM design. In 1967, John Shepherd-Barron invented and installed an ATM in a Barclays Bank in London. Don Wetzel invented an American made ATM in 1968.
