Moses Judah Folkman, MD, founder and director of the Vascular Biology program at Children's Hospital Boston, was a visionary and scientific pioneer. When he first proposed, in the 1970s, that a cancer could be kept in check by cutting off its blood supply, he faced skepticism and even ridicule from a scientific community that wasn't ready for his ideas. But by the time of his death in early 2008, more than 1,000 laboratories worldwide were engaged in the study of angiogenesis, the field he founded; more than 10 new cancer drugs were on the market; and more than 1.2 million patients worldwide were receiving anti-angiogenic therapy.

This gallery offers just a few highlights of Folkman's long and productive career as a physician and researcher.
