To quote the BBC - "In his 1954 book, Motivation and Personality, Maslow explained his Heirarchy of Needs: how only when basic physiological needs, and those of safety and security, are met can humans aspire to be motivated by higher goals such as status and self-respect. And he maintained that only a small number of exceptional people - he gave Albert Einstein and Eleanor Roosevelt as examples - are capable of reaching the highest level of motivation, and are driven by the desire to accomplish all they are capable of.
Maslow was also a pioneer, with Carl Rogers, of Humanistic Psychology - a response to the sharply opposing schools of psychoanalysis and behaviourism which dominated psychology at the time.
Claudia Hammond visits Brandeis University outside Boston, where Maslow was the founding Professor of Psychology, to speak to some who knew him, and hears from psychologists and management experts how his influence persists. Contributors include Margie Lachman - Professor of Psychology at Brandeis University, Lawrence Fuchs - emeritus Professor of American Civilization and Politics at Brandeis (who died last month), and Warren Bennis - Professor of Management and Organization at the USC Marshall School of Business."
If you read this after the 19th then you should be able to track it down on the BBC iPlayer.
You can read a little more about applied Maslovian theory (allegedly) by doing a search on this blog for "Dave and his hierarchy of needs". You can even find a Maslow game to play there. Dave, in case you were wondering, is doing well.
