Cyparissos Stephanos

Kyparissos Stefanos (; May 11, 1857 - December 27, 1917) was a Greek author, mathematician, and professor. He was a pioneer in 20th century projective geometry. He studied with Vassilios Lakon. Stefanos furthered his studies in France following the same path of Timoleon Argyropoulos, Dimitrios Stroumpos, and Vassilios Lakon. In France, Stefanos studied with Jean Gaston Darboux, Camille Jordan, and Charles Hermite. Jean Gaston Darboux was his doctoral advisor. He wrote articles in the fields of mathematical analysis, higher algebra, theoretical mechanics, and topology. He published around twenty-five original works in European journals. He is known for introducing Desmic system.

He received his PhD in 1878 from the National and Kapodistrian University of Athens. In 1879 he became a member of l'Société mathématique de France. In the early 1880s he studied mathematics in Paris and published many papers in various journals. He returned to Greece and in 1884 was appointed honorary professor and in 1890 regular professor at the National and Kapodistrian University of Athens. He was also a professor at the National Technical University of Athens and the Hellenic Naval Academy. Stefanos was an invited speaker at the International Congress of Mathematicians in 1897 at Zurich, in 1900 at Paris, in 1904 at Heidelberg, in 1908 at Rome, and in 1912 at Cambridge (England).
