This French Southern and Antarctic Territories (TAAF) stamp, issued in 1987, honors Robert Gessain (1907–1986), a physician, ethnologist, and explorer. Known for his pioneering Arctic expeditions and anthropological research, Gessain significantly advanced the study of Inuit culture and human adaptation to extreme climates. The portrait design, by artist Claude Jumelet after Pierre Béquet’s engraving, captures his thoughtful and resilient character. With a face value of 3.40 francs, this issue highlights France’s tradition of commemorating eminent scientists and explorers connected to polar and overseas research.
