Thomas Hakon Gronwall Wikipedia
Thomas Hakon Gronwall or Thomas Hakon Gronwall (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. Gronwall worked for about a year as a civil engineer in Germany before he immigrated 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.
In 1925 he started to collaborate with Professor Victor K. La Mer, which led to his joining the Department of Physics at Columbia University as an associate in 1927. This connection was a great opportunity. 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. He developed a solution to higher approximation in the Debye-Huckel theory.
