The article describes the struggle of Dr. Jeremiah Stamler v. HUAC (Honorable House Committee on Un-American Activities) in defense of free speech and the viability of science. dr. Stamler, a prominent scientist in the prevention of cardiovascular disease, faced a HUAC hearing in the 1950s for his views on international cooperation and disease prevention. His case and a statistical analysis prepared by Professor Hans Zeis of the University of Chicago was a key reason why Congress eventually disbanded HUAC. Stamler's work has included nearly 800 publications, the training of hundreds of young scientists, and a leadership role in cardiology prevention at the local, national, and international levels. According to Dr. Geoffrey Rose Stamler confronted cardiovascular diseases, promoted the role of diet in their control, which has become an accepted truth today, and contributed more than anyone to the decline of the problem in many countries.
