Joseph Lister

A

“Aseptic Technique” in surgery, used phenol to treat instruments, dressings and wound to control microbial growth

42
Q

Louis Pasteur

A

Disapproved spontaneous generation, credited for initiating “Aseptic Technique” in the laboratory, proved microbes are everywhere & can’t negotiate curves
