Vilhelm Bjerknes

Died 9 Apr 1951 at age 89 (born 14 Mar 1862).Vilhelm F(riman) K(oren) Bjerknes was a Norwegian meteorologist and physicist, one of the founders of the modern science of weather forecasting. As a young boy, Bjerknes assisted his father, Carl Bjerknes (a professor of mathematics) in carrying out experiments to verify the theoretical predictions that resulted from his father's hydrodynamic research. After graduating from university, Bjerknes moved on to his own work applying hydrodynamic and thermodynamic theories to atmospheric and hydrospheric conditions in order to predict future weather conditions. His work in meteorology and on electric waves was important in the early development of wireless telegraphy. He evolved a theory of cyclones known as the polar front theory with his son Jakob.
