The Krebiozen Hoax: How a Mysterious Cancer Drug Shook Organized Medicine

The most recent book-length treatment of the Krebiozen affair, drawing on archival research at the University of Illinois and the A.C. Ivy papers at the American Heritage Center (University of Wyoming). Ehrlich reconstructs how Ivy, Senator Paul Douglas, and author Rachel Carson supported an unproven cancer treatment despite consistent negative findings by independent investigators, and situates the episode in the broader context of 1950s cancer panic and challenges to scientific authority. The book was published August 2024 by the University of Illinois Press.
