John Hunter and the Descent of the Testis

The descent of the testis and the development of an inguinal hernia were the earliest published scientific work by John Hunter, the Scottish surgeon and anatomist who is acknowledged as the father of scientific surgery. Hunter's anatomic descriptions are the ones we use today to describe the prenatal descent of the testis and to explain the pathogenesis of an undescended testis and inguinal hernia in infancy. His work appeared in print in 1762, not as a formal publication but as an addendum to a screed written by his older brother William publicly accusing Percival Pott of pirating John's observations on the pathogenesis of an inguinal hernia and publishing them as his own, an early example of scientific rivalry.
