My work overthrew many of the hitherto-uncontested doctrines of the second-century anatomist Galen, and caused a storm of criticism from other anatomists because I wanted to prove them wrong with some of there assumptions about the human body. Galen studied the animal body or mainly apes instead of the human to make his discoveries on human anatomy . Some of my influences were Jacques Dubois and Jean Fernel, when I studied under them in university I found my interest in anatomy. Also my family had been established in  medicine for several generations.
