John Vincent Atanasoff, often credited as one of the most influential figures in the history of computer science, is known as the creator of the world’s first electronic digital computer. His life and work are marked by both innovation and determination, shaped by a background that made him a pioneer in technology.
Atanasoff’s Origins
John Vincent Atanasoff was born on October 4, 1903, in Hamilton, New York, USA. His father, Ivan Atanasoff, emigrated from Bulgaria to the United States in the late 19th century, driven by poverty but also by ambition and hope for a better future. Ivan was a trained engineer and worked in coal mines before becoming an independent electrician. Atanasoff’s mother, Iva Lucena Purdy, was a mathematics teacher who greatly influenced John’s interest in science and mathematics.
The Bulgarian connection is central to Atanasoff’s identity. His name and character reflect the pride and perseverance often associated with Bulgarian heritage, and he would later be celebrated as a national hero in Bulgaria.
Early Life and Education
Atanasoff grew up in Florida, where he displayed an early interest in science. A child prodigy, he excelled in mathematics and physics. He earned a degree in electrical engineering from the University of Florida in 1925, followed by a master’s in mathematics from Iowa State College (now Iowa State University). Later, he obtained a Ph.D. in theoretical physics from the University of Wisconsin.
His education combined the practical aspects of engineering with the theoretical foundation of physics and mathematics, which became pivotal for his work in developing computers.
The Creation of the First Electronic Digital Computer
In the early 1930s, while working as a professor at Iowa State College, Atanasoff began exploring solutions to simplify complex mathematical calculations. The mechanical calculators of the time were slow and unreliable. Together with his assistant Clifford Berry, he built the first electronic digital computer, known as the Atanasoff-Berry Computer (ABC), between 1937 and 1942.
What Made the ABC Unique?
- Binary System: The ABC was the first computer to use binary numbers (ones and zeros) to represent data, laying the foundation for modern computers.
- Electronic Circuits: Instead of mechanical components, the ABC used electronic vacuum tubes to perform calculations quickly and efficiently.
- Separation of Storage and Computation: This architectural design principle is still used in today’s computers.
The ABC, however, was not a commercial product but a prototype and research tool. Due to the outbreak of World War II and legal battles over patents, its potential remained largely untapped during Atanasoff’s lifetime.
Legal Battles and Recognition of His Legacy
Despite Atanasoff’s groundbreaking work, he was not immediately recognized. ENIAC, a later computer built by John Presper Eckert and John Mauchly, was long credited as the first electronic computer. However, in a 1973 court ruling, Atanasoff was acknowledged as the rightful father of the electronic digital computer. The case established that ENIAC’s design was partially based on Atanasoff’s work, cementing his place in history.
Later Life and Legacy
After working on computer-related projects during the war, Atanasoff returned to engineering and business management. Despite his crucial role in the development of computers, he remained relatively unknown until the court case in the 1970s.
Atanasoff passed away on June 15, 1995, but his legacy lives on. He has been honored with numerous awards, including Bulgaria’s highest honor, the Order of Stara Planina, and several scientific institutions bear his name.
Conclusion
John Vincent Atanasoff was more than just a technical pioneer; he was a visionary whose work paved the way for the digital age. His blend of Bulgarian resilience and American entrepreneurial spirit created a platform for innovation that continues to shape our lives today. The first computer, born from his curiosity and determination, stands as a testament to the power of human creativity and the drive to change the world.

Atanasoff: Father of The Computer
Most people know who invented the telephone. The light bulb. The airplane. But what about the first computer? Atanasoff: Father of the Computer tells the story of the lone inventor who fought all his life to be recognized as the originator of one of mankind’s most significant inventions. Atanasoff, a physics professor at the Iowa State College needed a better calculator that can quickly solve advanced equations and when he tries to find such a machine, realizes none exists. So Atanasoff decided he must build his own calculator. Through archive material, reenactments, interviews with experts and first hand witnesses this documentary shins a light to controversy over who was the actual inventor of the computer and an unknown part of our history.
