Alex Faickney Osborn in the context of "Brainstorming"

Brainstorming is a creativity technique in which a group of people interact to suggest ideas spontaneously in response to a prompt. Stress is typically placed on the volume and variety of ideas, including ideas that may seem outlandish or "off-the-wall". Ideas are noted down during the activity, but not assessed or critiqued until later. The absence of criticism and assessment is intended to avoid inhibiting participants in their idea production. The term was popularized by advertising executive Alex Faickney Osborn in the classic work Applied Imagination (1953).
