CLU is a software application developed in the 1970s as a programming language. It drew significant influence from ALGOL 60, a foundational language in structured programming. Additionally, CLU incorporated concepts from Lisp, particularly in its approach to data abstraction and functional programming elements. The language also integrated ideas from Simula, notably its object-oriented programming paradigms, which shaped CLU’s design and implementation.

The synthesis of these influences allowed CLU to introduce novel features, such as clusters—a construct for encapsulating data and operations. These clusters were an early form of abstract data types, reflecting the combined principles of its predecessors. While not as widely adopted as some contemporary languages, CLU’s innovations contributed to later developments in software engineering.
