Alex F. Osborn is perhaps best known for inventing and popularizing the Brainstorming technique. After developing and testing the technique within his ad agency BBDO, he popularized the concept in 1948 in his bestselling book Your Creative Power.

Brainstorming: “using the brain to storm a creative problem—and doing so in commando fashion, with each stormer attacking the same objective.” (Osborn, Your Creative Power)
