A thought leader’s Hierarchy of Needs

In 1943 Maslow Abraham published an extraordinary paper, A Theory of Human Motivation. I was planning to write that he came up with the following hierarchy of needs model.

But if you read the original paper, you can see that there wasn’t actually a model. Just a list. (As an interesting aside, this points to the power of a model. The impact of seeing the visual is much greater than just having a list, and I always associate Maslow’s work with the visual model, even though it wasn’t his.)
