Martin Seligman is usually ascribed as the major pioneer of positive psychology. He was made the president of the American Psychological Association in the late 1990s and decided to highlight it during his time in that role. Nevertheless, Seligman was building on the work of humanist psychologists that had come earlier, such as Abraham Maslow and Erich Fromm. In fact, Maslow is often regarded to have coined the term positive psychology in his book, Motivation and Personality, which was first published in 1954.
