Pierre Rosenstiehl

Pierre Rosenstiehl (5 December 1933 – 28 October 2020) was a French mathematician recognized for his work in graph theory, planar graphs, and graph drawing.

The Fraysseix-Rosenstiehl's planarity criterion is at the origin of the left-right planarity algorithm implemented in [http://pigale.sourceforge.net Pigale] software, which is considered the fastest implemented planarity testing algorithm.

Rosenstiehl was directeur d’études at the École des Hautes Études en Sciences Sociales in Paris, before his retirement. He was a founding co-editor in chief of the European Journal of Combinatorics. Rosenstiehl, Giuseppe Di Battista, Peter Eades and Roberto Tamassia organized in 1992 at Marino (Italy) a meeting devoted to graph drawing which initiated a long series of international conferences, the International Symposia on Graph Drawing.

He has been a member of the French literary group Oulipo since 1992. He married the French author and illustrator Agnès Rosenstiehl. Provided by Wikipedia
