Smalltalk-76 / Smalltalk-80 Releases

Smalltalk, a groundbreaking object-oriented programming language, introduced concepts like Model-View-Controller (MVC) and a highly interactive development environment. Its integrated class hierarchy provided the conceptual foundation for future frameworks.

Significance

Smalltalk was instrumental in pioneering object-oriented design principles and the idea of a comprehensive, extensible software system, directly influencing the architectural patterns later adopted by application frameworks.
