MONTICELLO, NY — Career educator Tony Nappo will lead a discussion of Rebecca Skloot’s book “The Immortal Life of Henrietta Lacks” at the Ethelbert B. Crawford Public Library on Thursday, August 6 at 6:30 p.m. While her name was Henrietta Lacks, scientists know her as HeLa. She was a poor black tobacco farmer whose cells, taken without her knowledge in 1951, became one of the most important tools in medicine, vital for developing the polio vaccine, cloning, gene mapping and more. Henrietta’s cells have been bought and sold by the billions, yet she remains virtually unknown, and her family can’t afford health insurance. This New York Times bestseller tells a riveting story of the collision between ethics, race, and medicine; of scientific discovery and faith healing; and of a daughter consumed with questions about the mother she never knew. This program is free and open to the public; doors open at 6:15 p.m.
