Casseri was a brilliant anatomist and professor at the University of Padua, whose life was overshadowed by the eternal rivalry with his mentor Fabrizio. After his death, history also turned its back on him and a host of unfortunate events gave his disciple, Spiegel, credit for many of his achievements. Despite an unquestionable anatomical legacy, he is still is forgotten today in many texts specializing in the field. As a tribute to his work we propose to call the semilunar hernia, the Spiegel-Casseri Hernias.
