Hermann von Helmholtz (1821-1894) |
Hermann Ludwig Ferdinand von Helmholtz was a major figure of 19th-century science. One of his most fundamental contributions was to clarify the first principle of thermodynamics (conservation of energy). He is also credited with the idea (1854) that noncreasing entropy would ultimately bring about the heat death of the Universe.
Before the discovery of radioactivity and the advent of nuclear physics, Helmholtz and Kelvin (1824-1907) suggested that the source of the heat generated by the Sun might be due to a slow gravitational contraction in a classical process now known as Kelvin-Helmholtz contraction. This was advocated in a famous article published in 1862 by Sir William Thomson (Lord Kelvin) entitled The Age of the Sun's Heat (doc, pdf).
