Robert “Bob” Crapo, one of the giants in pulmonary medicine, died December 26, 2015 from the effects of Alzheimer's disease. Bob was a long-time professor of medicine at the University of Utah. His academic career was distinguished by his work in standardizing pulmonary function testing. Along with colleagues Alan Morris, Richard Kanner, and Reed Gardner, he co-authored a book on pulmonary function testing, widely known as "the orange manual". He was chairman of the Pulmonary Function Testing Committee of the American Thoracic Society and was an integral part of an international collaboration with the European Respiratory Society. A few of the honors he received during his career include the Distinguished Scientist Award from the American College of Chest Physicians, the Distinguished Achievement Award from the American Thoracic Society, and the Legacy of Life Scientific Award from the Deseret Foundation's Heart-Lung Research Institute. He is survived by his wife Susan and four children. In lieu of flowers the family has asked consideration of a donation to the Alzheimer's Association or Neighborhood House of Salt Lake City.
