Meet Thomas Edison: Ten Thousand Ways
MentorMind

Menlo Park
Edison's greatest invention wasn't the phonograph or the practical bulb — it was the industrial research lab: a building full of talented people iterating on schedule ('a minor invention every ten days, a big thing every six months'). Innovation stopped being lightning and became a process.
The filament hunt
For the incandescent light he tested thousands of materials — platinum, beard hair, bamboo from Japan — and called none of it failure: 'I've found ten thousand ways that won't work.' He also fought the current war dirty and lost it to Tesla and Westinghouse's better technology; our Edison concedes that chapter honestly.
Why they belong at your table
Seat him when your tenth attempt just failed. His scoreboard starts at ten thousand, and he's still cheerful about it.
