Luther Simjian vs John Shepherd-Barron vs Don Wetzel
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.
However, it wasn't until the mid to late 1980s that ATMs became part of mainstream banking.
Luther Simjian's ATM

After six months, the bank reported that there was little demand for the new invention and discontinued its use.
