Thomas Hakon Grönwall
Swedish mathematician (1877–1932)
From Wikipedia, the free encyclopedia
Thomas Hakon Grönwall or Thomas Hakon Gronwall (born Hakon Tomi Grönwall;[1] January 16, 1877 in Dylta bruk, Sweden – May 9, 1932 in New York City, New York) was a Swedish mathematician. He studied at the University College of Stockholm and Uppsala University and completed his Ph.D. at Uppsala in 1898. Grönwall worked for about a year as a civil engineer in Germany before he emigrated to the United States in 1904. He later taught mathematics at Princeton University and from 1925 he was a member of the physics department at Columbia University.[1][2]

In 1925 he started to collaborate with Victor LaMer, which led to his joining the Department of Physics at Columbia University as an associate in 1927[citation needed]. This connection was a great opportunity[according to whom?]. There were no teaching obligations; he had complete control of his own time and an abundance of new intriguing problems to address in physical chemistry and in atomic physics[citation needed]. He developed an analytical solution to the Poisson-Boltzmann equation as it appears in the Debye–Hückel theory[1]
