Andreas Vesalius, the influential Belgian anatomist, is well-known for his significant contributions to the field of human anatomy. His dedication to direct observation and hands-on study was exemplified by his enthusiastic support for anatomical dissection. He believed in the importance of examining the human body up close to gain accurate knowledge, which was a departure from the reliance on ancient texts that dominated his time.

In "Stiff: The Curious Lives of Human Cadavers," Mary Roach emphasizes Vesalius's hands-on approach as a vital part of understanding human anatomy. By encouraging practical experience with dissections, he not only advanced the scientific study of the body but also challenged the norms of the Renaissance period, promoting a more empirical and engaged method of learning.
