First Edition. Ackermann studied medicine under von Siebold and Soemmering and later taught at the universities of Mainz, Jena and Heidelberg. He began his anatomical studies of hermaphrodites around 1798, and in 1805 published his Infantis androgyni historia et ichnographia, in which he described his anatomical investigation of a hermaphrodite infant, cited several similar cases, and presented, in a separate section, his theories on sex and procreation. The work is illustrated with five engraved plates showing the infant's genitalia in progressive stages of dissection.
