NAS (December 19, 1903 – June 6, 1996) was an American mouse
geneticist and basic
transplant immunologist.

Snell specifically "discovered the genetic factors that determine the possibilities of transplanting tissue from one individual to another. It was Snell who introduced the concept of H
antigen
In immunology, an antigen (Ag) is a molecule, moiety, foreign particulate matter, or an allergen, such as pollen, that can bind to a specific antibody or T-cell receptor. The presence of antigens in the body may trigger an immune response.

This experience "served to convince me that research was my real love," Snell wrote in his autobiograph
If it were to be research, mouse genetics was the clear choice and the
Jackson Laboratory, founded in 1929 by
Dr. Clarence Cook Little, one of Castle's earlier students, almost the inevitable selection as a place to work." The Jackson Laboratory was (and still is) the world's mecca for mouse genetics.
From 1933 to 1934, Snell was a teacher at
Washington University in St. Louis.

and he remained there for the entire balance of his long career. In Bar Harbor, he met and married Rhoda Carson. Together they had three sons, Thomas, Roy, and Peter. In his leisure time, Snell enjoyed skiing, a passion he developed during his years at Dartmouth, as well as tennis.
Snell received the Cancer Research Institute
