Career
Kreindler was born on 15 October 1931 in
Brăila
Brăila (, also , ) is a city in Muntenia, eastern Romania, a port on the Danube and the capital of Brăila County. The ''Sud-Est'' Regional Development Agency is located in Brăila.

, Romania into a Jewish family. She obtained in 1951 a fellowship and spent the next four years in the USSR studying mathematics at the
Ural State University, located in Sverdlovsk (nowadays
Yekaterinburg).
In 1955, she completed a master thesis on ''"Multiplicative Lattices with Additive Basis"'' under the supervision of
Petr Grigor'evich Kontorovich, before returning to Bucharest to join the faculty of Mathematics at the
Polytechnic Institute of Bucharest. Next to her duties as assistant professor, she continued with her research in the field of
functional analysis under the guidance of
Grigore Moisil.
She earned her Ph.D. thesis in mathematics on the "''Theory of Pseudolinear Operators"''. In 1969 she was promoted to associate professor. Kreindler married fellow mathematician Dinu Wexler and changed her name to Eléna Wexler-Kreindler. She left Romania with her husband in 1972 to move to France.
She had to start a new professional career in Paris, first as untenured and later tenured associate professor at the
Pierre and Marie Curie University
