Kay also contributed to the development of the Dynabook concept. His work paved the way for modern personal computing.
Barbara Liskov
Barbara Liskov was born in Los Angeles, California, in 1939. She earned a Ph.D. in computer science from Stanford University in 1968. Liskov is a pioneer in programming languages and system design. She developed the CLU programming language and the Liskov Substitution Principle. CLU introduced new ways to handle data abstraction and module architecture. The Liskov Substitution Principle became a key concept in object-oriented programming. Liskov also worked on distributed systems and fault tolerance. Her research has shaped modern computing practices.
John Backus
John Backus was born in Philadelphia, Pennsylvania, in 1924. He earned a master’s degree in mathematics from Columbia University. Backus led the team that developed FORTRAN, the first high-level programming language. He also created the Backus-Naur Form (BNF), a notation for defining syntax. FORTRAN made programming more accessible and efficient. It became the standard for scientific and engineering applications. BNF provided a formal way to describe programming languages. Backus’s innovations laid the groundwork for future language development.
Frances E. Allen
Frances E. Allen was born in Peru, New York, in 1932. She earned a master’s degree in mathematics from the University of Michigan. She developed techniques to improve the efficiency of computer programs. Allen’s research in parallel computing paved the way for high-performance computing. In 2006, she became the first woman to receive the Turing Award. Her work continues to influence modern computing.
Donald Davies
Donald Davies was born in Treorchy, Wales, in 1924. He studied physics at Imperial College London. Davies is best known for his work on packet switching. Packet switching allows data to be broken into small packets and sent independently. This innovation made efficient and reliable communication possible. Davies’s work was independently mirrored by Paul Baran in the US. Together, their ideas led to the creation of ARPANET.
