Marcantonio della Torre was an anatomist and professor at the University of Pavia around the 16th century. While emplyed there, he and Leonardo da Vinci worked closely togehter, studying corpses and annotating findings. It was believed they had intentions of publishing an anatomy book together. Unortunatley, della Torre died in 1511 from the plague and thus the countless papers never got published, keeping both della Torre and da Vinci and the hidden fathers of anatomy.
