Dill, David Bruce, 1891-

David Bruce Dill was a physiologist in the study of exercise, sports medicine and applied sciences. His research focused on the effects of temperature exposure, high-altitudes, diet, age and fatigue on the human body. Dill received his bachelor's degree from Occidental College in Los Angeles, California and both his master's and doctoral degrees from Stanford University in Stanford, California. He began his physiology career at Harvard’s Fatigue Laboratory in its inaugural year, 1927. While working at Harvard, Dill led a research trip to Southern Nevada after he discovered at least sixteen men had died of heat exhaustion in one year while working on the Hoover Dam project. Dill and his team quickly discovered the workers suffered because of a loss of salt due to excessive perspiration while laboring. Dill’s cure was to add higher amounts of salt to workers’ diets which resulted in no further deaths related to heat exhaustion during the Hoover Dam project. The research conducted at the Fatigue Laboratory influenced his first and most influential book, Life, Heat, and Altitude: Physiological Effects of Hot Climates and Great Heights. Published in 1938 the book is a foundational work that investigates the reactions of living organisms to stress. After the dissolution of the Fatigue Laboratory in 1947, Dill left Harvard to direct medical research at the Army Chemical Center’s Research and Development branch in Maryland. During his time at the center, he oversaw research that helped standardize the mouth to mouth method of artificial respiration for the Army. In 1961, Dill left the Army Chemical Center’s Research and Development branch and moved to Bloomington, Indiana to continue research at Indiana University. Dill’s research is cited in a NASA technical note published in 1966. Dill moved for the final time in 1966 to Las Vegas, Nevada where he worked for the Desert Research Institute, an affiliate of the Nevada System of Higher Education (NSHE). While in Las Vegas, he replicated studies he had done at the Harvard Fatigue Laboratory with visiting professors and science students from Boulder City High School. He remained a research professor until 1976, and died in 1986.
