Eleanor Roosevelt and Antoine de Saint-Exupery are described as strongly developed self-actualizing people. They were selected as subjects of this study because they are generally believed to possess self-actualizing characteristics and because their positions as public figures made it more likely that data on them would be accessible. Self-actualization (SA) is interpreted in accordance with Abraham Maslow's view of it as a characteristic of psychologically healthy individuals who are free of disturbing neuroses, know how to satisfy their basic needs, use their unique abilities in positive ways, and are intrinsically motivated by transcendent values such as truth, beauty, and justice. The specific purpose of the paper is to complement Maslow's theories of SA by providing concrete examples of how SA developed in two individuals. Information is presented on the background and activities of Roosevelt and de Saint-Exupery, comparison of the types of actualizing engaged in by each of them, review of relevant theories (particularly, the theories of Abraham Maslow on SA and on psychological health and the theories of Dabrowski and Piechowski on levels of development of SA behavior), and on specific traits of SA. The research methodology centered on a content analysis of personal documents of Roosevelt and de Saint-Exupery, including autobiographies, letters, and biographical material. Findings from comparison of the SA profiles of Roosevelt and de Saint-Exupery indicated that they were basically similar, although Roosevelt was somewhat more of a doer/reformer and de Saint-Exupery more an originator of ideas. Implications of SA for education are discussed. (DB)
