True Valor


Barney Clark and the Utah Artificial Heart

On December 2, 1982, the fully mechanical Jarvik-7 heart was placed inside Barney Clark, culminating years of painstaking research and making medical history by successfully pumping Clark’s blood for 112 days. True Valor takes an in-depth look at this significant event by telling the story of the doctors and researchers involved, of Barney Clark, and of the evolution of the artificial heart before and after Clark’s transplant. Author Don Olsen is well positioned to tell this story, having worked on the artificial heart project under Dr. Willem Kolff, the man behind the Jarvik-7. His narrative conveys the concerns and emotions of those who were part of Clark’s story while offering the insights of one who knows that research does not happen overnight but takes time, resources, and the efforts of many people. Olsen’s account shares the human sides of this story along with the embedded politics and technical details of medical research in clear, readable language. 

Donald B. Olsen is professor emeritus of bioengineering at the University of Utah. As a veterinarian and researcher, he worked on the development of the artificial heart, testing its functionality in calves. Today he is the president of the Utah Artificial Heart Institute. 

Praise and Reviews:
“Dr. Barney B. Clark . . . was ‘an incredible man, one of the strongest men I have ever known, one of the strongest families I have ever known. He did a service to mankind and the knowledge that we will gain from him will serve us all.’”
—hospital spokesman John Dwan announcing the death of Barney Clark; quoted in the New York Times, March 24, 1983

“Dr. Barney Clark may have seemed quite ordinary, but he did extraordinary things. The happy portions of human history are so often created by seemingly ordinary men and women doing extraordinary things to benefit others; Dr. Barney belonged to that happy tradition.”
—from the funeral oration by Neal A. Maxwell, of the Quorum of the Twelve Apostles, The Church of Jesus Christ of Latter-day Saints

“An enticing read… Olsen tells a tale of 'pioneering science,' drawing from University of Utah records as well as his own personal papers, to narrate a story of research perseverance, overcoming challenges, and the advancement of a life-saving technology.”—Journal of the History of Medicine
