Description

Ivan Edward Sutherland runs the Sketchpad program on a TX-2 computer. The program, used for engineering design, uses an early graphical user interface to support basic drawing functions.

Original caption 1: "In the Lincoln Laboratory "Sketchpad" program, a student operates the TX-2 computer on which has been developed a computer-aided design program. The engineer can draw, erase, magnify and reduce rough portrions of a form in front of a console with a light pen (like a stylus). At the same time he has fed pertinent information into the numerical part of the computer. The computer then completes the engineer's design, eliminating quantities of intermediate drawings and tasks of the draftsman".

Original caption 2: "Sketchpad, a system by which computer-generated graphis could be manipulated, was developed by Lincoln Laboratory and was the forerunner of much more sophisticated methods."
