"Charles Townes, the Columbia University physicist who transformed modern society with his invention of the maser and the laser, receiving the 1964 Nobel Prize in physics for his effort, has died. He was 99."He died Tuesday, January 27, 2015.
Townes (born July 28, 1915) was one of three people born in 1915 that I had in this year's list of people born 100 years ago who was still alive. The other two are David Rockefeller (born June 15, 1915) and Herman Wouk (born May 27, 1915.) You can see the main list here and a short follow up post here.
