"Who will bell the cat?" Andrew C. Ivy and Krebiozen

The authoritative medical-historical account of the Krebiozen affair. Ward traces Ivy's career arc from distinguished physiologist and Nuremberg medical expert to advocate for an unproven cancer remedy, and documents how he resisted retraction even after independent analysis refuted the drug's efficacy. The article establishes the timeline of Ivy's introduction to Stevan Durovic, the 1951 press conference, the sequence of AMA and NCI investigations, and Ivy's response to each critique. Ward's treatment is the standard scholarly reference cited in subsequent reviews of the affair.
