Sandwiches are named after the Fourth Earl of Sandwich. Apparently meat was put between slices of bread for him so he could continue to stay at the gaming tables without interruption for meals. This projectile exploded in flight, sending out potentially deadly shell fragments. A French physician, J. I. Guillotin, developed a speedier and more efficient method of administering the death penalty than the previously used tortures. His invention is now known as the guillotine.
Eponyms are common in medicine.
These are names given to a disease or process identified, described, or developed by a scientist or physician. Two common laboratory tests that use eponyms are the Gram stain and the Pap smear. The Gram stain is a method for staining tissue and microorganisms for microscopic analysis. Smears are fixed by flaming, stained in a solution of crystal violet, and treated with iodine solution, rinsed, decolorized, and then counterstained. Another common medical eponym is the Pap smear test.
