Igor Yourievitch Bogdanoff and Grégoire Yourievitch Bogdanoff, who sometimes spelled their surname Bogdanov, were born on Aug. 29, 1949, in a castle in the town of Saint-Lary-Soulan, a ski resort nestled in the French Pyrenees along the Spanish border. Their father, Youri Ostasenko-Bogdanoff, was an itinerant painter who said he was descended from a Tatar prince and who had fled Russia as a boy. The brothers are survived by their half brother, François Davant, and their sisters Laurence, Géraldine and Véronique Bogdanoff. After “Temps X” ended in 1987, the Bogdanoffs wrote “Dieu et La Science” (1991), about the relationship between religion and science. The brothers settled out of court in 1995, having in the meantime begun their graduate studies.
