During the greater part of the nineteenth century, the school was the "great Liberal High School" on the right bank with its relatively flexible regime that was chosen by the progressive bourgeoisie for its sons. It is among the few schools in Paris that never had students as boarders: students who were not living with their parents worked, ate and slept in the neighbourhood via a network of "maitres de pension". The mix has gradually emerged in 1924 for preparatory classes for the grandes écoles, and 1975 for secondary classes.
Over the course of its history the school has changed name several times:
Lycée de la Chaussée d’Antin (1804)
Lycée impérial Bonaparte (1805 – 1814)
Collège royal de Bourbon (July 1815 – February 1848)
Lycée impérial Bonaparte (1848 – 1870)
Lycée Condorcet (22 October 1870 – 1874)
Lycée Fontane (1 May 1874 – 27 January 1883)
Lycée Condorcet (since 1883)
Preparatory classes are also very old and were treated to famous teachers such as Jean-Paul Sartre.
