Electronic Discrete Variable Automatic Computer Edvac
Arthur Burks' Contributions to EDVAC
Arthur Burks was a prominent figure in the history of computing. Born on September 13, 1898, and passing on May 13, 1974, Burks was not only an American Marine officer and fiction writer but also a groundbreaking computer scientist who played a significant role in the development of early computers like the Electronic Discrete Variable Automatic Computer (EDVAC).
Role in EDVAC
Burks was one of the key contributors to the development of the EDVAC, a crucial component in the evolution of computer architecture. The EDVAC was designed to implement the new stored-program concept, which was revolutionary at the time. This concept was famously documented in the First Draft of a Report on the EDVAC by John von Neumann.
Arthur Burks, along with other collaborators like J. Presper Eckert and John Mauchly, was instrumental in the design and development process of EDVAC at the Moore School of Electrical Engineering. His work primarily focused on the logical design and operational implementation of EDVAC's components.
Contributions to Computer Science
Additionally, Burks was a pioneer in the introduction and advocacy of the Reverse Polish Notation scheme, which was part of his broader interest in the development of computing logic and algorithms. His work in this area further cemented his reputation as a formidable figure in the field of computing.
Burks’ involvement in the development of the ENIAC, alongside his efforts on the EDVAC, illustrates his significant contributions to the early stages of electronic computing. His work laid foundational stones for subsequent developments in computer architectures, influencing the design of subsequent machines such as the IAS machine and the ORDVAC.
Burks and Philosophy
Arthur Burks also held a deep interest in the philosophical implications of computing. He was associated with philosophers like Paul Weiss and contributed to the discussions on the logical frameworks that underlie computer science philosophies.
Legacy and Impact
Arthur Burks’ legacy is evident in the myriad of ways he impacted the early development of computers. His work on EDVAC not only advanced technological capabilities but also enriched the theoretical frameworks that continue to underpin modern computing.

Key Contributors to EDVAC
The Electronic Discrete Variable Automatic Computer (EDVAC) was a crucial development in the history of computing, succeeding the ENIAC and laying the groundwork for modern computer architecture. Its construction and conceptualization involved several pioneering figures whose contributions were pivotal.
John Mauchly and J. Presper Eckert
John Mauchly and J. Presper Eckert were instrumental in the initial proposal and design of the EDVAC. Both had previously worked on the development of the ENIAC, and their experiences significantly influenced the architectural improvements implemented in the EDVAC. Mauchly and Eckert focused on creating a machine that would utilize stored programs, a groundbreaking concept at the time. Their work on the ENIAC's logical design informed the enhancements seen in the EDVAC, such as its use of binary rather than decimal systems.
John von Neumann
John von Neumann played a critical role in disseminating the concepts that would form the basis of the EDVAC through his "First Draft of a Report on the EDVAC." This document outlined the architecture of a stored-program computer, introducing principles such as the stored program and binary computation. Although von Neumann's draft did not explicitly credit all contributors, it heavily drew on insights from his collaborations with Mauchly and Eckert.
Herman Goldstine
Herman Goldstine, a mathematician and physicist, facilitated the collaboration between the Army and the developers. His role was crucial in securing funding and support from the U.S. Army's Ballistic Research Laboratory. Goldstine's coordination efforts ensured that the project moved forward despite the technical and logistical challenges that arose during its development.
Arthur Burks
Arthur Burks, a prominent computer scientist, also contributed to the logical design of the EDVAC. Burks, who had worked alongside von Neumann, Mauchly, and Eckert, played a key role in refining the machine's architecture. His input was vital in the transition from the ENIAC's cumbersome plugboard programming to a more efficient stored-program model.

Electronic Discrete Variable Automatic Computer (EDVAC)
The Electronic Discrete Variable Automatic Computer (EDVAC) was one of the pioneering designs in the era of early electronic computers. It was a significant advancement over its predecessor, the Electronic Numerical Integrator and Computer (ENIAC), in that it was designed as a stored-program computer. This was a crucial innovation that laid the groundwork for future computer architectures.
Background
Work on the EDVAC began in August 1944 at the Moore School of Electrical Engineering at the University of Pennsylvania. The computer was part of the U.S. Army's Ballistic Research Laboratory initiatives during World War II, aiming to enhance the precision and efficiency of ballistic calculations.
Key Contributors
The primary architects of the EDVAC included John Mauchly and J. Presper Eckert, who were also instrumental in the development of the ENIAC. They proposed the construction of EDVAC in August 1945, with the project officially commencing in April 1946. John von Neumann also played a crucial role in the project as a consultant. His contributions were especially notable in the realm of logical design, which he summarized in his "First Draft of a Report on the EDVAC" in 1945.
Design and Architecture
Unlike the ENIAC, the EDVAC was designed to be a binary rather than decimal computer, marking a significant shift in computing methodology. It was a serial computer, meaning it processed one operation at a time in sequence. The design included automatic capabilities for addition, subtraction, multiplication, and programmed division, and it featured an automatic checking mechanism to ensure accuracy.
A notable technological feature of the EDVAC was its ultrasonic serial memory, which had a capacity of 1,024 44-bit words. This memory was based on delay line technology, which utilized the propagation of sound waves through a medium as a means of storage—a precursor to modern random-access memory (RAM).
Von Neumann Architecture
The conceptual foundation of the EDVAC's design was based on what is now known as the von Neumann architecture. This architectural model established that a computer's program and the data it processes should be stored in the same memory space. This was a revolutionary departure from earlier designs that required separate storage for instructions and data.
Impact and Legacy
The EDVAC represented a significant evolution in computing history, influencing subsequent computers such as the Electronic Delay Storage Automatic Calculator (EDSAC) and the Manchester Mark 1. It demonstrated the feasibility and advantages of the stored-program concept, which became the standard for computer architecture in the subsequent decades.
The concepts developed for the EDVAC, particularly those documented by von Neumann, have had enduring impacts on the field of computer science, forming the basis for the design of almost all modern computers. This makes EDVAC not just a historical artifact but a cornerstone in the evolution of digital computing.
