J.C. Bose: 60 GHz in the 1890s
JC Bose is a hero of mine. He was a polymath - Contributions in physics (linked article) are well know. But he is also the person who proved what is universally taken as granted: Plants are alive.The was also a great detractor of the idea of intellectual property -- he made all of his discoveries deliberately available to the public domain.His handling of racial discrimination at the colonial British was also pretty bad-ass!His wiki page is a good start.https://en.wikipedia.org/wiki/Jagadish_Chandra_Bose
