Yale Jr., Linus
airplaneLinus Yale Jr. (1821-1868) was an American mechanical engineer and manufacturer who developed the cylinder pin-tumbler lock (and other key and combination locks). Yale's father, Linus Yale, had invented an earlier pin-tumbler lock in 1848; the son's lock used a smaller, flat key with serrated edges (like the ones we still use today). There is no connection between Linus Yale and Yale University.

Yalow, Rosalyn S.
Dr. Solomon A. Berson (1919-1972) and Dr. Rosalyn Sussman Yalow (1921- ) co-invented the radioimmunoassay (RIA) in 1959. The radioimmunoassay is a method of chemically analyzing human blood and tissue and is used diagnose illness (like diabetes). RIA revolutionized diagnoses because it uses only a tiny sample of blood or tissue and is a relatively inexpensive and simple test to perform. Blood banks use RIA to screen blood; RIA is used to detect drug use, high blood pressure, infertility, and many other conditions and diseases. For inventing RIA, Yalow won the Nobel Prize in Medicine in 1977 (Yalow accepted for Berson, who died in 1972). Yalow and Berson did not patent the RIA; instead they allowed the common use of RIA to benefit human health.
