Many noteworthy but I like that Feb 6 the first retirement home opened in Prescott Arizona

The guy on the right in the picture is Heike Kamerlingh Onnes. He is credited with:

Liquifying He-4 (7/10/1908)
Discovering superfluidity in He-4 (1908)
Discovering superconductivity (1911)

There have been several Nobel prizes for work on superconductivity, but Onnes got his in 1913 for liquid he.

Maybe he retired to Prescott.
