Georges Henri Reeb (12 November 1920 – 6 November 1993) was a France mathematician. He worked in differential topology, differential geometry, differential equations, topological dynamical systems theory and non-standard analysis.
Early life and education
Reeb was born in Saverne, Bas-Rhin, Alsace, to Theobald Reeb and Caroline Engel.[1] He had a sister, Gertrude.[1] Saverne is located about 40 km (25 mi) from Strasbourg.[1]
In 1943 he received his PhD from University of Strasbourg (that had been evacuated during the war to Clermont-Ferrand) with the dissertation Propriétés topologiques des variétés feuilletées. His adviser was Charles Ehresmann.[1]
Career
In 1954, he was at the Institute for Advanced Study.
In 1965 Reeb, Jean Leray and Pierre Lelong founded a series of encounters between theoretical physicists and mathematicians in Strasbourg (Rencontres entre Mathématiciens et Physiciens Théoriciens).
He was a professor at Université Joseph Fourier in Grenoble and Université Louis Pasteur in Strasbourg where he directed the Institute for Advanced Mathematical Research at University of Strasbourg between 1967 and 1972, which he founded with Jean Frenkel in 1966.[2]
Reeb was the founder of the topological theory of foliations (Feuilletages, Blätterungen), manifolds with a special local product structure. He invented what is now called the Reeb foliation, a foliation of the 3-sphere, all the leaves of which are diffeomorphic to R2, except one, which is a (compact!) 2-torus.[3]
Reeb sphere theorem says that a compact manifold with a function with exactly two critical points is homeomorphic to the sphere. This is used to prove that the Milnor spheres, although not diffeomorphic, are homeomorphic to the sphere S7, a result that came in 1956.
Other terms named for Reeb are:
- Reeb graph
- Reeb vector field
- Reeb stability theorem
Reeb received an honorary doctorate from the Albert-Ludwigs-Universität Freiburg and from the Université de Neuchâtel.

Personal life and demise
Reeb died in Strasbourg, France.[1] He was 72 years old.
