Julian Bigelow (1913–2003)

Basic Facts

  • Full name: Julian Himely Bigelow
  • Born: 19 March 1913, Nutley, New Jersey
  • Died: 17 February 2003, Princeton, New Jersey

Family Background

Born in Nutley, New Jersey. Little is known about his parents. As a child, he showed remarkable mechanical aptitude – at age three, he methodically disassembled door knobs and reassembled them.

Education

  • Master’s degree: Massachusetts Institute of Technology (MIT), electrical engineering and mathematics, 1936. He worked his way through MIT, delivering milk in a Model T Ford. Norbert Wiener later recalled Bigelow arriving in a “very decrepit vehicle” that “would have died months ago.”

Career Timeline

Early Career (1936–1943)

  • 1936–1938: First job after MIT graduation was with Sperry Corporation.
  • 1938: Joined IBM, where he worked on improving the reliability and serviceability of automatic machinery.

Wartime Cybernetics Work (1940–1945)

  • During World War II, collaborated with Norbert Wiener at MIT on research concerning automated fire control systems for anti-aircraft guns. This work led to the development of the Wiener filter.
  • 1943: Co-authored “Behavior, Purpose and Teleology” with Wiener and Arturo Rosenblueth, published in Philosophy of Science. This seminal paper – one of the founding documents of cybernetics – explored how mechanical, biological, and electronic systems could interact through feedback. It instigated the formation of the Teleological Society and later the Macy Conferences on cybernetics, with Bigelow as an active participant in both.

IAS Machine: Chief Engineer (1946–1952)

  • March 1946: Hired by John von Neumann as “his engineer” to construct one of the first digital computers at the Institute for Advanced Study. Von Neumann hired him on Wiener’s recommendation.
  • Bigelow served as chief engineer and architect of the IAS machine. He designed a parallel 40-bit architecture with 24-microsecond memory access time – achievements that, as George Dyson wrote, “appeared to defy the laws of probability given the reliability of electronic components at that time.”
  • His expertise in fault-tolerance and reliability, developed during wartime fire-control work, became fundamental to the machine’s design.
  • The machine used 40 Williams tubes for its main memory, containing 1024 words in total, each tube using a 32x32 array. Problems with initial tube designs forced a switch to Williams tubes (cathode-ray tube storage).
  • The IAS machine’s design was freely published by von Neumann, leading to approximately 15 clones being built worldwide and profoundly influencing subsequent general-purpose computer architecture. The IBM 701, IBM’s first all-electronic stored-program computer, was directly modeled on Bigelow’s design.

Physical Constraints and Institutional Resistance

The project faced significant challenges. It was initially housed in the boiler room of Fuld Hall. Bigelow had to navigate institutional resistance from the IAS’s pure-science community, which was uncomfortable with applied engineering’s encroachment on their scholarly sanctuary. There were salary disparities between engineers and mathematicians, and Cold War concerns about weapons applications of the computer added political tension.

Permanent Member at IAS (1950–2003)

  • December 1950: Named Permanent Member of the Institute for Advanced Study, initially in the School of Mathematics.
  • 1951–1952: Received a Guggenheim Fellowship.
  • 1970: Moved to the School of Natural Sciences.
  • For decades, provided consulting services for the Atomic Energy Commission, RCA, the National Academy of Sciences, and other public and private entities.

Personality

Described by George Dyson as “more physicist and theoretician than engineer,” despite his engineering title. His core research interest lay in “the relationship between logic, computability, perhaps machine languages” – the scientific potential of computing rather than mere machine-building.

Obscurity in Computing History

Despite his pivotal role in designing one of the most influential computers ever built, Bigelow remains relatively unknown compared to contemporaries like von Neumann, Eckert, and Mauchly. Several factors contributed to this obscurity:

  • He was an engineer in an institution of theoretical scientists.
  • Von Neumann, the public face of the project, received most of the credit.
  • Bigelow was quiet and scholarly, not inclined toward self-promotion.

After his death in 2003, his family gave George Dyson access to his papers. Dyson’s sorting and study of these papers contributed to Turing’s Cathedral: The Origins of the Digital Universe (2012), which brought Bigelow’s contributions back into view.

Connections to Others in the Story

  • John von Neumann: His employer and the visionary behind the IAS computer project. Von Neumann championed Bigelow’s permanent membership at IAS.
  • Norbert Wiener: Wartime collaborator on anti-aircraft fire control; recommended Bigelow to von Neumann.
  • Klara Dan von Neumann: Programmed MANIAC I, which was built on the IAS machine design Bigelow engineered.
  • Herman Goldstine: Served as assistant director, then director, of the IAS computer project alongside Bigelow.
