Robert Greene.

Robert Greene (born May 14, 1959, in Los Angeles, California) is an American author best known for his books on strategy, power, and human nature. He studied classical studies at the University of Wisconsin–Madison and worked in over fifty different jobs — including magazine editor, Hollywood writer, and translator — before publishing his first book. In 1998, he co-wrote "The 48 Laws of Power" with book packager Joost Elffers after meeting him at an art school in Italy. The book became a global phenomenon, selling millions of copies and influencing politicians, executives, entertainers, and athletes worldwide. He followed it with "The Art of Seduction," "The 33 Strategies of War," "Mastery," and "The Laws of Human Nature." Greene's work draws on centuries of history and psychology to reveal the hidden dynamics of power and human behavior.
