Abstract
During the years of my association with Dr. Bull in the laboratory, I seldom heard him talk about his boyhood or his efforts to get an education. Only occasionally would he describe some small incident of his early life. Since his death I have discovered, in accumulating the material for this account of him, just how stirring and courageous was his fight to attain his end against difficulties that would have discouraged a less hardy soul. It is the same moving story of endurance with which histories of our pioneers are filled.
Carroll Gideon Bull was born June 22, 1884, in Sevier County, Tennessee. He was the son of Nancy Emma and William Gernade Bull, the fourth child in a family of eleven, of whom nine lived to reach maturity. His parents came of English and Pennsylvania Dutch stock, but his family had lived in Tennessee for a hundred years.
