Aha Moment: Dr. Ehrlich’s Magic Bullet

When Richard Rifkind was a kid, Hollywood made dramatic biopics about scientific pioneers like Paul Erlich, who invented an early cure for syphilis — impressive men with impressive beards and German accents. Rifkind became a scientist himself, a leading cancer researcher. His treatment for lymphoma, 40 years in development, was approved this year by the FDA. Now retired from research, Rifkind is making movies himself to nurture the love of science. Produced by Jenny Lawton.
