Karl Wilhelm Pohlke

Karl Wilhelm Pohlke (28 January 1810 in Berlin – 27 November 1876 in Berlin) was a German painter who established an important geometric statement, which is fundamental for axonometric projections.

After finishing his studies he earned his living for some years painting landscapes and teaching perspective drawing privately.

After 10 years he returned in 1845 to Berlin, where he got 1849 at the Königlichen Bauakademie an appointment as lecturer and in 1860 was promoted to Professor for Descriptive Geometry and Perspective.

Between 1860 and 1876 he published a textbook on descriptive geometry, consisting of two volumes, where he introduced (in the 1st volume) his statement, later called "Pohlke's theorem" on axonometric projections: "Any three line segments
