D Frederick Herzberg
　　Although relatively few contemporary management students will have read his books, Herzberg s name is instantly recognisable to anyone who has studied industrial organisations. This is because the American psychologist was responsible for introducing the concept of motivation into management thinking.
　　As a young man, Herzberg became deeply interested in mental illness and the human need for mental and emotional satisfaction. This led him to criticise the approach of many companies to job design, and to argue for the need for job enrichment to stimulate employees efforts.
　　E Tom Peters
　　The American s reputation was created in the I 980s by the spectacular success of one book, In Search of Excellence, co-written with Robert Waterman. The two were working together as management consultants and no-one expected their first (and only) book to end up selling 5 million copies worldwide!
　　Although his ideas have been criticised, Peters popularity as a speaker and writer has continued to grow. So much so that Peters has created his own business to market books, videos and consultancy based on his work.
