In the 1950s, patent lawyers at Bell Labs noticed something they couldn't explain. The engineers filing the most patents weren't on the same team. They didn't share a discipline. Some were physicists. Some were electrical engineers. Some were mathematicians.
The one thing they had in common was lunch. Specifically, lunch with a quiet electrical engineer named Harry Nyquist.
Nyquist didn't give people ideas. He didn't run brainstorming sessions or lead innovation workshops. He asked questions. Good ones. The kind that made people from completely different fields realize they were working on different sides of the same problem.
That cross-pollination produced more breakthroughs than any formal program Bell Labs ever ran. The transistor. Information theory. The laser. The solar cell. All of them emerged from people who had nothing in common professionally bumping into each other in hallways, cafeterias, and shared offices.
You'll hear this story attributed to an MIT study or a Harvard paper. The actual source is Jon Gertner's The Idea Factory, drawing from Bell Labs' internal records. The story gets better when you tell it accurately.
What those patent lawyers stumbled onto has since been studied rigorously for 80 years. And the findings are remarkably consistent.
