First Edition, Rare Offprint Issue. In his landmark 1905 paper on special relativity, Einstein used the velocity-dependent concepts of transverse and longitudinal mass for the moving electron (these terms have now been replaced with the concept of relativistic mass, first defined by Lewis and Tolman in 1909). In the present paper Einstein proposed an experimental method for determining the ratio of the transverse to the longitudinal mass, and invited experimentalists to verify his special theory of relativity. Einstein later abandoned velocity-dependent mass concepts, stating in 1948 that “it is better to introduce no other mass concept than the ‘rest mass’ m” (quoted in L. B. Okun, “The concept of mass,” Physics Today (1989): 31-36). Lavenda, A New Perspective on Relativity, pp. 7-8. Weil, Albert Einstein Bibliography, 14.
