Glimpses of a Scientific Style
In august 1951, David Wheeler submitted a PhD dissertation titled Automatic Computing with the EDSAC to the faculty of mathematics (D. F. Hartley, personal communication, September 7, 2011) at the University of Cambridge. The year after, in November 1952, another of Maurice Wilkes’s students, Stanley Gill, submitted a thesis titled The Application of an Electronic Digital Computer to Problems in Mathematics and Physics. Wheeler’s was not the first doctoral degree awarded on the subject of computing. That honor must surely go to Herman Hollerith for his thesis submitted to Columbia University in 1890 on his invention of an electrical tabulating system (see Chapter 3, Section IV). Nor was Wheeler’s the first doctoral degree on a subject devoted to electronic computing. In December 1947, Tom Kilburn (codesigner with Frederic C. Williams of the Manchester Mark I [see Chapter 8, Section XIII]) had written a report on the CRT-based memory system he and Williams had developed (but called the Williams tube). This report was widely distributed in both Britain and the United States (and even found its way to Russia), and it became the basis for Kilburn’s PhD dissertation awarded in 1948 by the University of Manchester (S. H. Lavington, personal communication, August 31, 2011). Wheeler’s doctoral dissertation, however, was almost certainly the first on the subject of programming. And one might say that the award of these first doctoral degrees in the realm of computer “hardware” (in Kilburn’s case) and computer “software” (in Wheeler’s case) made the invention and design of computers and computing systems an academically respectable university discipline. As we have witnessed before in this story, establishing priority in the realm of computing is a murky business, especially at the birth of this new discipline. Thus, if by “computer science” we mean the study of computers and the phenomena surrounding computers (as three eminent computer scientists Allan Newell, Alan Perlis (1922–1990), and Herbert Simon suggested in 1967), then—assuming we agree on what “computers” are—the boundary between hardware and soft ware, between the physical computer and the activity of computing, dissolves.
