Pierre Lelong

Pierre Lelong (1912 to 2011) was a French mathematician who worked in the theory of several complex variables. Born in Paris, he won the first prize in mathematics in the Concours Général in 1928 and 1929 and entered the École Normale Supérieure in 1931. He began research under the guidance of Paul Montel and defended his state doctorate in Paris in 1941. After teaching at Grenoble and Lille he returned to the Faculty of Science in Paris in 1954. His books treat plurisubharmonic functions, positive differential forms and entire functions of several variables, the last written with Lawrence Gruman. Under Charles de Gaulle he served from 1959 as technical adviser to the presidency for scientific research, education and public health, and later led the commission on research planning. He married the mathematicians Jacqueline Ferrand and, later, France Fages. He died in Paris in 2011.
