پرتره صمیمی کلود برنارد (1813-1878)

Claude Bernard was a leading scientist which stunned the physiological concepts and introduced the experimental medicine. Among other findings, he discovered the glycogenic function of the liver. Despite all honors and awards his academic career had caused, Claude Bernard was an ordinary man whom affective life was unhappy. His arranged marriage was unhappy while his wife became a virulent antivivisectionist activist. He had the misfortune of losing his two sons and was deeply affected by the death of his mother. During the last years of his life, a platonic relation with Sarah-Marie Raffalovitch, a very smart young woman, gave him some comfort.
