title: [The singular story of Doctor Worm -Nicholas Andry de Boisregard- and of his daughters Parasitology and Orthopaedics].
abstract: Homini verminoso or Dr. Worm were the nicknames that Nicholas Aindry won in life for his consecration to the study of intestinal worms and for his bad temper, which led him to fiercely attack the surgeons. The article reassumes the studies and contributions that gave Andry the title of Father of Parasitology and the candidacy to Father of Orthopaedics, and mentions some other candidates to this honor. Quite a man, he had -besides his biological one- two famous daughters, growing till our days; wrote at least three valuable books; and planted the immortal "tree of Andry", the symbol of Orthopaedics.
