I am saddened to see that Dr Harold L. Osher (of the Osher Map Library) passed away on Dec. 23. He was a great map collector and philanthropist. I remember him as a wonderful and knowledgeable mentor during my 8 years at the map library.https://www.pressherald.com/2023/12/27/obituaryharold-l-osher-m-d-2/RegardsGeorge-----------------------------Dr. George S.
