Dr Eugenie Clark was born 100 years ago Wednesday (May 4th). She was a marine scientist and ichthyologist who became known as the "Shark Lady" for her discoveries that changed public perception of sharks, and became the scientific founding figure of what is now Mote Marine Lab. The U.S. Postal Service is honoring her with a stamp. We speak with Mote CEO Dr. Michael Crosby about Clark's life and work.
