In respect to the medieval practice of giving surnames based on ones profession and based on the hereditary transmission from generation to generation, Bäumler (1980) suggested a genetic-social theory of assortative distribution of traits of body build such as height, weight, and stature in a population of men called ‘Smith’ (German: Schmied) and ‘Tailor’ (German: Schneider). From this theory the hypothesis was deduced that among the top ranking athletes of the ‘heavy weight’ branches of athletics, which require body strength and body height, there are relatively more persons that go by the name of Schmied than in the ‘light weight’ branches of athletics, which are more stamina demanding, where more persons go by the name of Schneider. At the same time, complementary hypotheses assuming less Schneiders among the heavy weight branches than expected and less Schmieds among the light branches of athletics than expected under the null hypothesis of no statistical association were also tested. All hypotheses were empirically supported by applying the data of two independent samples.
