“I associate Seymour with childlike wonder, a sense of exploration, creating instead of receiving knowledge. And, in my own career I haven't had a linear path—it’s been more of a ‘zig zag’ that's taken me much further than some straight line would have. I credit Seymour for that gift.” – Steve Strassmann, visiting scientist at Harvard Medical School
"I remember being shocked that Seymour thought we should destroy all the schools, and then being equally surprised that, a breath later, he was excited about the project that he was about to undertake in the schools. He could take these seemingly contradictory ideas, hold them in juxtaposition, and make sense of them." – Rena Upitis, education professor at Queen's University in Kingston, Ontario
“Seymour’s class really resonated with me; and was a central influence on how I understand things. To this day, he’s one of the people I quote when explaining things—in an operational sense, rather than abstract, meaning that you understand something to the extent you can use it." – Bob Frankston, spreadsheets inventor, developer, writer
