History of Object-Oriented Programming (1 Point)


Ivan Sutherland

Ivan Sutherland wrote a revolutionary computer program called Sketchpad in 1963 in the course of his PhD thesis. It helped change the way people interact with computers. Sketchpad is considered to be the ancestor of modern computer-aided drafting (CAD) programs as well as a major breakthrough in the development of computer graphics in general. Ivan Sutherland demonstrated with it that computer graphics could be utilized for both artistic and technical purposes in addition to showing a novel method of human-computer interaction.

Alan Kay

Alan Kay is one of the founders of the idea of object-oriented programming, along with some colleagues at PARC and predecessors at the Norwegian Computing Centre. He is the conceiver of the Dynabook concept which defined the basics of the laptop computer and the tablet computer and he is also considered by some as the architect of the modern windowing graphical user interface (GUI).
