ASTON, Francis William (1877-1945). Isotopes. London: E. Arnold, 1922.
8o (216 x 137 mm). 4 half tone plates, text illustrations. Original dark blue cloth, gilt-lettered spine (very minor wear). Provenance: THE AUTHOR'S COPY (signature, ink and pencil manuscript additions, 2 loosely inserted sheets of type-written lecture notes); Franz Sondheimer, chemist and bibliophile (bookplate).
THE AUTHOR'S COPY OF THE FIRST EDITION. Aston began researching the different atomic weights of two forms of neon at Cambridge in 1913, under the guidance of J.J. Thomson (discoverer of the electron). He left to fight in the First World War, but later continued, replacing Thomson's parabola apparatus with the mass spectograph he had himself invented. This gave more concentrated effects and so greater clarity of identification. He won the Nobel Prize for chemistry in 1922 for his discovery of the isotopes of a large number of non-radioactive elements. PMM 412; Norman 77.
