What did Frederic Mohs do?

In 1933, 23-year-old Frederic Edward Mohs was a research assistant assigned to inject different chemicals into cancerous rat tissues to produce specific reactions. He discovered that one of these chemicals, a zinc chloride solution, could “fix” skin tissue for microscopic study — preserve it without changing the architectural structure of the cells. 2 He combined zinc chloride solution with stibnite and sanguinaria canadensis to develop a cohesive paste. When he applied the paste, Mohs found that he could excise the tissue without causing bleeding. He could then prepare frozen sections of the excised tissue, and placed them on slides to be viewed under the microscope. Thus began his groundwork for the technique that today bears his name.
