Barbara Liskov
Computer Scientist & Programming Pioneer
About
Barbara Liskov is an American computer scientist at MIT who has made fundamental contributions to programming language design, software engineering, and distributed systems. She developed the Liskov Substitution Principle, a cornerstone of object-oriented programming that states objects of a subtype should be substitutable for objects of their base type. Her work on CLU introduced data abstraction and iterators, concepts now standard in modern programming. She received the 2008 Turing Award for her practical and theoretical advances in programming language design.
