https://en.wikipedia.org/wiki/Lars_Onsager Lars Onsager Career and research In 1925 he arrived at a correction to the Debye-Huckel theory of electrolytic solutions, to specify Brownian movement of ions in solution, and during 1926 published it. He traveled to Zurich, where Peter Debye was teaching, and confronted Debye, telling him his theory was wrong. He impressed Debye so much that he was invited to become Debye's assistant at the Eidgenossische Technische Hochschule (ETH), where he remained until 1928.[7]
