Uncommon letter by the quantum pioneer
Description  

German theoretical physicist (1868-1951) who pioneered developments in atomic and quantum physics. ALS in German, signed “A. Sommerfeld,” one page, 5.5 x 8.75, October 11, 1903. Letter to physicist Stefan Meyer, an eminent student of Boltzmann and pioneer of the study of radioactivity, who later served as director of the internationally renowned Vienna Institute for Radium Research. In part (translated): “Thank you very much for your…friendly communication, I transmit herewith my manuscript along with figures. I hope that the work will not or does not substantially exceed the desired amount of 1/2 sheet and would be very grateful if they can be included in the anniversary publication still.” In fine condition. At this time, Sommerfeld was working with Felix Klein, Ludwig Prandtl, and Rudolf Mehmke to standardize the definitions and notation of vector analysis. A desirable piece of correspondence between important early physicists. Pre-certified PSA/DNA.
