James Henry Williams Jr. is a mechanical engineer, consultant, civic commentator, and teacher of engineering. He is currently Professor of Applied Mechanics in the Mechanical Engineering Department at the Massachusetts Institute of Technology (MIT). He is regarded as one of the world's leading experts in the mechanics, design, fabrication, and nondestructive evaluation (NDE) of nonmetallic fiber reinforced composite materials and structures. He is also Professor of Writing and Humanistic Studies at MIT.
Williams began his career in 1960 as an apprentice machinist at the Newport News Shipbuilding and Dry Dock Company. Within eight years he graduated from The Apprentice School, earned SB and SM engineering degrees from MIT, and returned to the Shipyard as a senior design engineer. Within another two years, he earned a PhD from the University of Cambridge, where he conducted theoretical elasticity and shell theory. He then chose to join the faculty at MIT, where he has spent the bulk of his career.
