Karl Doehlemann
1864–1926
A German mathematician of the late 19th and early 20th centuries, he wrote clear, compact books that helped bring projective geometry, geometric transformations, and perspective to a wider audience. His work sits at the meeting point of pure mathematics and visual understanding.

Grundzüge der Perspektive nebst Anwendungen

About the author
Born in Freising on April 20, 1864, and dying in Munich on March 22, 1926, Karl Doehlemann was a German mathematician. Standard biographical records identify him simply and firmly with that field, and surviving library and archival records show a career centered on geometry.
Doehlemann is best remembered through his mathematical books, especially works on projective geometry, geometric transformations, and perspective. Titles associated with him include Projektive Geometrie in synthetischer Behandlung, Geometrische Transformationen, and Grundzüge der Perspektive nebst Anwendungen, which suggest a writer interested not only in formal theory but also in making spatial ideas easier to grasp.
For modern readers, that makes him an appealing figure in the history of mathematics: a scholar whose books connect abstract geometric thinking with the practical problem of how we represent space. Even when the details of his life remain lightly documented online, his published works give a clear sense of his interests and lasting contribution.
