Gerald Jay Sussman (born February 8, 1947) is the Panasonic Professor of Electrical Engineering at the Massachusetts Institute of Technology (MIT).

Sussman developed, with his graduate students, sophisticated computer-aided design tools for Very Large Scale Integration (VLSI).

[5] Using the Digital Orrery, Sussman has worked with Jack Wisdom to discover numerical evidence for chaotic motions in the outer planets.

[citation needed]z Sussman was also the lead designer of the Supercomputer Toolkit, another multiprocessor computer optimized for evolving of ordinary differential equations.

The Supercomputer Toolkit was used by Sussman and Wisdom to confirm and extend the discoveries made with the Digital Orrery to include the entire planetary system.

[6][7] Sussman has pioneered the use of computational descriptions to communicate methodological ideas in teaching subjects in Electrical Circuits and in Signals and Systems.

Over the past decade Sussman and Wisdom have developed a subject that uses computational techniques to communicate a deeper understanding of advanced classical mechanics.

Sussman and Wisdom, with Meinhard Mayer, have produced a textbook, Structure and Interpretation of Classical Mechanics (SICM), to capture these new ideas.
