Édouard Leon Cortès was born in Lagny-sur-Marne, a few miles east of Paris. As an adolescent, he became fascinated with the arts and at seventeen began his studies at the Ecole des Beaux-Arts in Paris.
The year 1901 marked the artist's first exhibition at the Salon des Artistes Francais. His piece depicting a dramatic Paris street scene at dusk brought him immediate recognition and fame.
Later, as an active member of the prestigious Societe des Artistes Francais, Cortes exhibited his works yearly in Paris at the Society's salon as well as at the Salon des Independants, and the Salon d'Hiver.
