THE ORIGINS OF MASLOW’S PYRAMID

For years I searched for the person who first drew a pyramid (or a triangle) to represent Maslow’s idea of the hierarchy of needs. And for years, I was not able to find it. But now, having recently found out who did that, the secret is out.

The first hint of a Hierarchy of Needs which somewhat gives the impression of a pyramid appeared in 1957. Keith David, a prominent scholar of the era, and a person that Bridgman ways would have been moving in the same circles as Douglas McGregor. What appeared in a book on Human Relations in Business by Keith Davis, as an illustration for the book of Maslow’s idea.
