In 1969, Jon Beckwith and his colleagues succeeded in isolating a gene from the chromosome of a living organism. Announcing this startling achievement at a press conference, Beckwith took the opportunity to issue a public warning about the dangers of genetic engineering. Jon Beckwith's book, the story of a scientific life on the front line, traces one remarkable man's dual commitment to scientific research and social responsibility over the course of a career spanning most of the postwar history of genetics and molecular biology.

The Double-Edged Helix explores the impact of recent genetic discoveries on both different population segments and society as a whole. The authors address the medical and ethical implications of the new technologies, outlining potential positive and negative effects of genetic research on minorities, individuals with disabilities, and those of diverse sexual orientations. Presenting a wide array of perspectives, this book emphasizes the need to ensure that research into genetics research does not result in discrimination against people on the basis of their DNA.
