Alfred H. Thiessen
Alfred Henry Thiessen (born April 8, 1872 in Troy , NY ; † 1956) was an American meteorologist .
Career
He began his career as a weather observer in Pittsburgh on July 1, 1898. As an assistant to the weather office (today: NOAA - National Oceanic and Atmospheric Administration ) he worked in Helena , Washington , Point Reyes and Manteo , then as a clerk in Mount Weather , Raleigh , Indianapolis , Salt Lake City , Portland , Baltimore and Denver . He left the weather bureau on December 11, 1920 to serve as a captain in the US Army. He returned from active service as a major on March 17, 1941 and retired on April 30, 1942.
Thiessens best-known work from 1911 deals with the description of weather forecasts with a geometric method for dividing the earth's surface, which is already known as Dirichlet tessellation (1850) or Voronoi diagrams (1908), but obviously not used in meteorology for interpolating measured values was. The synonym “ Thiessen polygons ” has become established for this method.
