Diane Marie McKnight ’75, SM ’78, PhD ’79, kept a bronze oarlock used for securing an oar on a boat. “I sand-casted it myself as part of my last class in mechanical engineering, and I learned how to use a lathe,” she said.

Amy (Schonsheck) Simpkins ’03 got her Institute keepsake early— a “cheap hoodie sweatshirt that was on special at the Coop the first week of my freshman year.” She still wears it almost every day.

Alan Paul Lehotsky ’73 said that in addition to his brass rat, he still has the Groucho glasses he wore to graduation. He admitted that the mustache has not held up very well.

Elliot Owen ’18, SM ’20, still has the precision-machined aluminum flexures that he used for his graduate research. “It is easy to create structures with a low stiffness in the direction of travel and high stiffness in all other directions,” he said. “I keep them on my bookshelf and show them off when I have people over. Most people are very surprised to see a solid piece of metal flex and move so easily and without friction.”

Walt Gibbons ’73, SM ’75, had the most popular response, provided by 22 of the 69 alums interviewed. He named his MIT brass rat.
