I am a university professor researching Thomas Hakon Gronwall, a Swedish-American mathematician who did work in physics and physical chemistry. In the late 1920s, he was a research associate at Columbia University and worked extensively in physical chemistry with Victor K. LaMer on Debye-Huckel theory and with K. W. Lamson on reflection of radiation in plates. Gronwall also published papers on the hydrogen and helium wave equations, the latter posthumously in 1937 after his notes were collected and organized by F. Bohnenblust and J. H. Bartlett Jr.
I would appreciate hearing from anyone who has knowledge of Gronwall’s life and work, especially regarding his time at Columbia University and the influence, if any, of his work on the development of the respective research areas.
