Influential in establishing computer science as an independent discipline of science coined the term software engineering. Proposed the stack for expression evaluation, with Edsger W. The modem speed unit baud is named after him. įrench telegraphic engineer patented the Baudot code, the first means of digital communication.

Published a series of briefings and papers about dividing information into 'message blocks' and sending them over distributed networks (1960–1964). One of two independent inventors of the concept of digital packet switching used in modern computer networking including the Internet.

Three brothers who wrote the Book of Ingenious Devices, describing what appears to be the first programmable machine, an automatic flute player. Led the team that created FORTRAN ( Formula Translation), the first practical high-level programming language, and formulated the Backus–Naur form that described the formal language syntax. Outstanding contributions to database technology. Originated the concept of a programmable general-purpose computer designed the Analytical Engine and built a prototype for a less powerful mechanical calculator. ĭeveloped bit vector notation and program control-flow graphs first female IBM Fellow (1989) first female recipient of the ACM's Turing Award (2006).īuilt the first electronic digital computer, the Atanasoff–Berry Computer, though it was neither programmable nor Turing-complete.

The term algorithm is derived from the algorism, the technique of performing arithmetic with Hindu–Arabic numerals popularised by al-Khwarizmi in his book On the Calculation with Hindu Numerals. Ingenious contribution and making public-key cryptography useful in practice.Ĭonceived and co-designed the Harvard Mark I.
