Because of the nature of his profession, he became intimately familiar with the explosion of scientific and technological advances flooding the medical profession as the new century approached. Advances in disease control pioneered and developed by Louis Pasteur, for example, seemed particularly promising at the time. (Yet even today the significance of Pasteur’s work cannot be overstated.) Many advances were in some way related to cleanliness and sterilization. Rubber surgical gloves became common physician’s raiment. Steam heat-treated surgical instruments ensured that bacteria were destroyed before surgery was performed.
