Karl Wilhelm Pohlke
Karl Wilhelm Pohlke (born January 28, 1810 in Berlin ; † November 27, 1876 there ) was a German history , genre , portrait and landscape painter who found the " Sentence of Pohlke " named after him for perspective painting .
Life
Karl Wilhelm Pohlke received his painter training from Wilhelm Hensel at the Royal Prussian Academy of the Arts in Berlin and made his debut at the art exhibition there in 1832. After completing his studies, he earned his living for a few years with landscape painting and gave private lessons in the technique of perspective drawing. In 1835 Pohlke went to France, where he trained at the Paris École des Beaux-Arts with Louis Étienne Watelet and Léon Cogniet and in 1843 to Italy. After a 10-year absence, he moved back to Berlin in 1845. There he got a position as a private lecturer at the Royal Building Academy in 1849 and in 1860 became professor for descriptive geometry and perspective at the building and at the same time at the art academy.
Between 1860 and 1876 he published a textbook in two volumes on descriptive geometry, which deals with the "Pohlke Theorem", or "Main Theorem of Axonometry ", named after him in the first volume:
"Every flat, genuinely two-dimensional 'tripod' OABC can be obtained as a parallel projection of a three-dimensional Cartesian tripod O'A'B'C '."
With this sentence , which he had struggled to prove in vain since 1853, he was the first to find a mathematical formulation and thus a theoretical justification for the method of representation used in painting practice since the Renaissance for architectural views or perspective freehand drawings. "The sentence itself is one of the artist's most remarkable contributions to mathematics."
