Klein, Oskar (1894-1977). Zur statistischen Theorie der Suspension und Lösungen. Inaugural-Dissertation . . . Arkiv för Matematik, Astronomi och Fysik 16, no. 5. 51pp. plus interleaves. Uppsala: Almqvist & Wiksells, 1921. 219 x 146 mm. Original printed wrappers, a bit soiled, light wear to spine. Very good. Author’s interleaved copy, with numerous equations, notes and corrections in Danish in pencil and ink on the interleaves.
First Edition of Klein’s dissertation for his doctorate in physics from Stockholm University, in which “he presented an important study of the statistical theory of suspensions and solutions based on Josiah Willard Gibbs’s statistical methods” (Dictionary of Scientific Biography). Klein presented his dissertation on 13 April 1921; it was printed on 9 May.
This interleaved copy contains numerous manuscript annotations, equations and remarks in Danish on the interleaves; although the notes are unsigned, the handwriting bears more than a passing resemblance to that of Niels Bohr. It is certainly plausible that Klein would send a copy of his thesis to Bohr upon its publication: Klein worked under Bohr at the Institute for Theoretical Physics during his student years, and would later become one of his closest collaborators. On the other hand, it is less likely that Klein would send Bohr any of his papers without first inscribing them to his honored teacher. The first interleaf in this copy is headed “14-5-21 Brev til Oskar!” [14 May 1921 Letter to Oskar!] and another interleaf following p. 50 is headed “25/5/21”; this indicates that whoever annotated Klein’s thesis was doing so shortly after its publication.Book Id: 50983
