Inspired by Which mathematicians died very young or in a tragic way? , I wonder which physicists had similar fates.
A quick search lead me to Heinrich Hertz who died from a malignant bone condition at 36. Ludwig Boltzmann is also known for committing suicide before seeing how important his contribution was to prove the existence of atoms. Paul Ehrenfest had also a very tragic story that I am unable to write down here. What are some examples? Be free to expand on the above cited. Was there some Galois kind of figure?
