Barbara Liskov

Barbara Liskov is a prominent American computer scientist known for her work in programming languages and software engineering. She developed the Liskov Substitution Principle, which states that objects of a superclass should be replaceable with objects of a subclass without affecting the program's behavior. This principle is fundamental in object-oriented programming, promoting code reuse and system reliability. Liskov's contributions also include developing the programming language CLU and advancing ideas in distributed computing. Her work has significantly influenced how software is designed and built, making systems more modular and understandable.
