In 1910 he graded as a naval architect from "Technische Hochschule Berlin" (Diplomingenieur Schiffbau). From 1911 Betz worked as a flow researcher at the Göttingen aerodynamic laboratory, where in 1919 he formulated a theory of 'ship-propellers with minimum loss of energy' within his "Dissertation" (PhD-work). In his 1920 paper "Das Maximum der theoretisch möglichen Ausnutzung des Windes durch Windmotoren (Theoretical possible maximum use of wind by wind-engines)" he formulated a law (usually referenced to him, but there's also some comparable work of F.W. Lanchester[1915] on the same subject), which states that one can convert less than 16/27 (or 59%) of the kinetic energy in the wind to mechanical energy using a wind turbine. His book "Wind-Energie und ihre Ausnutzung durch Windmühlen (Windenergy and its use by wind-mills)" published in 1926 gives a good account of the knowledge of wind energy and wind turbines at that period. 1911 (MCMXI) was a common year starting on Sunday (click on link for calendar). ...

In 1926 he became a professor at Göttingen, and from 1936 to 1956 succeeded Ludwig Prandtl as director of the aerodynamic laboratory.

Betz was awarded the Carl Friedrich Gauss medal of the West German Academy of Science in 1965. (30 April 1777 – 23 February 1855) was a German mathematician and scientist of profound genius who contributed significantly to many fields, including number theory, analysis, differential geometry, geodesy, magnetism, astronomy and optics. ...
