Who is Maurice Wilkes

Sir Maurice Vincent Wilkes was a pioneering British computer scientist, best known for his work in the development of the Electronic Delay Storage Automatic Calculator (EDSAC), one of the earliest stored-program computers. Born on June 26, 1913, in Dudley, Worcestershire, England, Wilkes made significant contributions to the field of computing during his career. Wilkes studied mathematics at the University of Cambridge and completed his PhD in physics. During World War II, he worked on radar technology, which involved significant computational challenges. This experience led him to the nascent field of electronic digital computing post-war. In 1945, Wilkes became the director of the University of Cambridge Mathematical Laboratory (later known as the Computer Laboratory), where he envisioned and led the construction of the EDSAC. The computer became operational in 1949 and was used for practical scientific computing, marking a significant milestone in computing because it was one of the first computers to store instructions in its memory, based on the von Neumann architecture, which conceptualizes the storage of data and program instructions in the same memory space. Wilkes is also known for his work on microprogramming, a method for using a small, specialized program to operate and control the more complex hardware of a computer's central processing unit (CPU). This concept greatly influenced computer design and is still in use in various forms. Over his career, Wilkes received numerous honors, including being knighted in 2000. He also served as the president of the British Computer Society and the Association for Computing Machinery (ACM). Maurice Wilkes continued to contribute to the field of computer science until his passing on November 29, 2010.

What inspired Maurice Wilkes to create the EDSAC

Maurice Wilkes was inspired to create the EDSAC (Electronic Delay Storage Automatic Calculator) primarily by the developments in electronic computing during and after World War II. His exposure to advances in digital computing, particularly his visit to the University of Pennsylvania to see the ENIAC (Electronic Numerical Integrator and Computer), played a crucial role. The ENIAC represented a significant step forward in the power of computing machines, and witnessing its capabilities firsthand provided Wilkes with both the inspiration and the realization of the potential for electronic computing. Upon returning to the UK, Wilkes aimed to build a practical computing machine that could be used for a range of scientific computations. His work at the University of Cambridge's Mathematical Laboratory put him in a position to pursue this goal. The EDSAC was designed to be a complete and practical computer for general use by other researchers, which was a somewhat novel approach at the time. By focusing on utility and reliability, Wilkes wanted to ensure that his machine could be used regularly and effectively to support scientific research, which indeed it did following its completion in 1949.

How did Maurice Wilkes contribute to computer science

Maurice Wilkes made several significant contributions to the field of computer science, particularly in the development of the Electronic Delay Storage Automatic Calculator (EDSAC), the ideas behind microprogramming, and his work on the concept of cache memory. 1. **EDSAC (Electronic Delay Storage Automatic Calculator)** - Completed in 1949, under the leadership of Wilkes, EDSAC was one of the first computers to have a practical implementation of stored program concept, which is a fundamental characteristic of virtually all modern computers. This meant that instructions were stored in the computer's memory along with the data. 2. **Microprogramming** - Wilkes also introduced the concept of microprogramming in 1951. This technique involves a level of computer instruction architecture that facilitates the implementation of complex instructions as sequences of simpler ones, thereby simplifying the hardware design of the computer and improving the maintainability and adaptability of the system. 3. **Cache Memory** - Wilkes was one of the first to formulate the concept of cache memories in 1965, systems that store copies of data from frequently used main memory locations to improve overall system performance. In addition to these technical contributions, Wilkes's leadership at the Cambridge University Mathematical Laboratory (now the Computer Laboratory, University of Cambridge) helped shape many future computer scientists and engineers through his teaching and research. He authored several influential texts and papers that have been fundamental in advancing the field of computer science.

What educational path did Maurice Wilkes follow

Maurice Wilkes pursued his education at the University of Cambridge in England. He earned his bachelor's degree in 1934 from St John's College, Cambridge, and continued his studies there to complete his doctorate in physics in 1936. His academic focus during his doctoral studies was on the propagation of radio waves in the upper atmosphere, a topic that was emerging and crucial at the time, particularly because of its implications for telecommunications and radar technologies. This educational foundation in physics and mathematics laid the groundwork for his later contributions to computer science and the development of early computing machines.
