Ludwig Boltzmann (1844-1906)Suicide in 1906

S = -k ln W

Boltzmann wrote in1898 “I am conscious of being only an individual struggling weakly against the stream of time.” Increasingly subject to depressions, Boltzmann committed suicide in 1906 only shortly before Perrin’s experiment on Brownian motion (1908) and Mililan’s oil-drop experiment (1909) provided very direct evidence for the discrete structure of matter.
