Donald Wetzel

Donald Wetzel was not the sole inventor of the Automated Teller Machine (ATM), but he played a significant role in its development. The ATM, a device that revolutionized banking and how people access their money, was the result of collaborative efforts by several individuals and companies. Here’s an overview of Donald Wetzel’s contribution and the development of the ATM:


  • Donald Wetzel was an American engineer and inventor who worked in the banking industry during the mid-20th century.
  • In the 1960s, banking faced challenges related to providing convenient access to cash and basic banking services outside of traditional banking hours.

Collaborative Invention:

  • Wetzel, along with his colleagues, John Shepherd-Barron and James Goodfellow, is credited with contributing to the concept and development of the ATM.
  • Shepherd-Barron, a Scottish inventor, is often regarded as the individual who came up with the idea of a self-service machine for dispensing cash.

Debut of the ATM:

  • The first true ATM, known as the “Docuteller,” was installed by Chemical Bank in Rockville Centre, New York, in September 1969.
  • This initial ATM allowed customers to withdraw cash by using a special paper voucher and a personal identification number (PIN).
  • Subsequently, James Goodfellow’s invention of the Personal Identification Number (PIN) system for ATM security further enhanced the technology.

Evolution of ATMs:

  • Over the years, ATMs evolved significantly. They began offering various banking services beyond cash withdrawal, such as balance inquiries, deposits, and funds transfers.
  • Advances in technology led to the development of networked ATMs that allowed customers to access their accounts from virtually any location.


  • The ATM revolutionized the banking industry by providing customers with convenient 24/7 access to their funds, reducing the need for in-person visits to bank branches.
  • ATMs also contributed to the growth of international banking networks, making it possible for travelers to access cash in foreign countries.


  • While Donald Wetzel was part of the team that contributed to the development of the ATM, the invention of the ATM is often attributed to a collective effort involving several inventors and banking institutions.
  • The ATM has become an integral part of modern banking, and its convenience has shaped how people manage their finances worldwide.

In conclusion, while Donald Wetzel was instrumental in the development of the ATM, the invention of this groundbreaking technology was a collaborative effort that transformed the way people access and manage their money. The ATM remains a vital component of the global banking infrastructure, thanks to the innovation and dedication of individuals like Wetzel and his colleagues.
