A Hungarian psychology professor, who emigrated to the United States at the age of 22. Now at Claremont Graduate University, he is the former head of the department of psychology at the University of Chicago and of the department of sociology and anthropology at Lake Forest College.

He is noted for both his work in the study of happiness and creativity and also for his notoriously difficult name, in terms of pronunciation for non-native speakers of the Hungarian language, but is best known as the architect of the notion of flow and for his years of research and writing on the topic. He is the author of many books and over 120 articles or book chapters. Martin Seligman, former president of the American Psychological Association, described Csikszentmihalyi as the world's leading researcher on positive psychology.

Csikszentmihalyi once said "Repression is not the way to virtue. When people restrain themselves out of fear, their lives are by necessity diminished. Only through freely chosen discipline can life be enjoyed and still kept within the bounds of reason." His works are influential and are widely cited.
