Charles Soret

Charles Soret (born 23 September 1854, Geneva, Switzerland; died 4 April 1904) was a Swiss physicist and chemist.

In 1872, Charles graduated from an art college in Geneva and, two years later, he added a degree in mathematics.

In 1879, he published his first discussion on thermodiffusion on the basis of experiments with solutions of NaCl and KNO3 in pipes with heated or cooled ends.

His experiments confirmed the results of C. Ludwig (published 20 years earlier) of which Soret probably did not know.

He died in April 1904 due to gastrointestinal illness, a few days after a successful operation.
