Visible Proofs is about the history of forensic medicine. Over the centuries, physicians, surgeons, and other professionals have struggled to develop scientific methods that translate views of bodies and body parts into "visible proofs" that can persuade judges, juries, and the public. The National Library of Medicine produced this exhibition. Visit the mini exhibit when the library is open. Monday -Thursday 7:30 am - 9pm. Friday 7:30 am to 5pm. Saturday and Sunday 10 am - 9 pm.
