Andreas Vesalius (physician)

Andreas Vesalius was a 16th-century scientist and physician renowned for revolutionizing the understanding of human anatomy. He challenged long-standing ideas by meticulously studying and dissecting human bodies, producing detailed and accurate anatomical drawings. His influential book, *De humani corporis fabrica*, provided a clearer and more precise view of the body's structure, laying the foundation for modern medicine. Vesalius emphasized that direct observation and hands-on study were essential for learning about the body, helping to correct many misconceptions from earlier teachings based on superstition and incorrect authority.
