This “important and pioneering book” (N.Y. Times Book Review) tells the inside story of the birth of the biotechnology industry. The “absorbing narrative” (New York Times) recounts the scientific race in the 1970s that led to the formation of Genentech and Biogen. In describing the competition to clone the human insulin gene, Invisible Frontiers is a “splendid piece of science writing” (Washington Post) that captures a historic moment in 20th century technological innovation.
