Ivan Sutherland Introduces the Sketchpad
Ivan Sutherland introduces the Sketchpad submitting his PhD thesis to MIT. The Sketchpad, one of the earliest programs for the TX-0, allowed direct manipulation of objects on a computer screen. Using the Sketchpad, a user could create and manipulate graphical figures with a light pen. This thesis provided the basis for later graphical user interfaces and is considered one of the seminal papers in computer science.
