I’d be surprised if you weren’t sitting within fifty feet of one of James Edward Maceo West’s most well-known inventions — the electret microphone. Although MEMS microphones have seen a dramatic rise as smartphone technology progresses, electret microphones still sit atop the throne of low-cost and high-performance when it comes to capturing audio. What’s surprising about this world-changing invention is that the collaboration with co-inventor Gerhard Sessler began while James West was still at university, with the final version of the electret springing to life at Bell Labs just four years after his graduation.

A Hacker’s Upbringing

James’ approach to learning sounds very familiar: “If I had a screwdriver and a pair of pliers, anything that could be opened was in danger. I had this need to know what was inside.” He mentions a compulsive need to understand how things work, and an inability to move on until he has unlocked that knowledge. Born in 1931, an early brush with mains voltage started him on his journey.
