Theophilus Müller (also known as Teofilo Molinatore and Theophilus Molitor) (Hersfeld 1576- Würzburg 1619 (?))[1] was professor of botany at the University of Ingolstadt.[2] He joined the Accademia dei Lincei in 1611.[3]
In 1621 Theophilus Müller and Giovanni Faber performed the first documented dissection of a rat. Their pregnant specimen appeared to have a penis and testes as well as a uterus, so they described it as a hermaphrodite. In fact the supposed penis was a clitoris, and the testes were vaginal glands.[4]
Federico Cesi had purchased the unpublished papers of the Fransicso Hernández expedition, part-edited by Nardo Antonio Recchi, containing a compendium of New World plants. There was a Lincean project to send Müller to Mexico to complete the necessary research for the publication,[5] but nothing appears to have come of it.[6]
