Nicht-Euklidische Geometrie Vorlesung by Felix Klein
Nicht-Euklidische Geometrie Vorlesung gehalten wahrend des Wintersemesters 1889-90 (and) Vorlesung gehalten wahrend des Sommersemesters 1890 by Felix Klein reproduced lithographically from the handwritten notes of his student, Frederick (Friedrich) Schilling. Gottingen. 1893. 7" x 8 1/2" 365 + 238 pages Hardcover with no dust jacket. Old cloth binding. I do not know if this is the original binding - probably not. Bright gilt lettering on spine.

Previous owner book plate inside the front cover. Another previous owner rubber stamp inside the front cover. Some small pencil notations on the preliminary remarks page and the page facing that page. I see no other previous owner markings. No tears, folds or creases to pages.

"Felix Christian Klein (German: [klaɪn]; 25 April 1849 – 22 June 1925) was a German mathematician and mathematics educator, known for his work in group theory, complex analysis, non-Euclidean geometry, and the associations between geometry and group theory. His 1872 Erlangen program classified geometries by their basic symmetry groups and was an influential synthesis of much of the mathematics of the time.
In 1871, while at Göttingen, Klein made major discoveries in geometry. He published two papers On the So-called Non-Euclidean Geometry showing that Euclidean and non-Euclidean geometries could be considered metric spaces determined by a Cayley–Klein metric. This insight had the corollary that non-Euclidean geometry was consistent if and only if Euclidean geometry was, giving the same status to geometries Euclidean and non-Euclidean, and ending all controversy about non-Euclidean geometry. Arthur Cayley never accepted Klein's argument, believing it to be circular." - wikipedia
