Barbara Liskov, a pioneer in computer science, made foundational contributions by reshaping how software correctness, modularity, and trust are perceived.
She emphasized the importance of building software like engineers build bridges, focusing on constraints, interfaces, and guarantees to combat chaos in programming.
Liskov is known for the Liskov Substitution Principle (LSP) and her work on abstraction barriers and strong specifications, which revolutionized software design and influenced languages like Ada, Python, Java, and Go.
Her legacy includes mentoring generations of computer scientists, shaping curricula, and paving the way for a world of software modules built on modular design and contractual promises.
