Answer:
My name is Andreas Vesalius and I'm a 16th-century Flemish anatomist, physician, and author of one of the most influential books on human anatomy, De Humani Corporis Fabrica Libri Septem. I am often referred to as the founder of modern human anatomy. I was born in Brussels, December 31, 1514 which was then part of the Habsburg Netherlands.

I was the first to perform public dissection on a human corpse, a practice that was unusual in the Middle Ages due to spiritual beliefs.
