He corresponded with other Liberal Catholics, among them Manzoni, Cesare Cantu, Dupanloup, and Montalembert.
As drafter of the Law of 1850 on Liberty of Teaching, he vainly endeavoured to prevent the return of the bill to the Council of State, 7 November 1849, and in the decisive debate (14 January to 15 March 1850) he seconded the efforts of Montalembert, Parieu, and Thiers which resulted in victory for the Catholics.
Charles Forbes René de Montalembert (March 18, 1810 London - March 13, 1870 Paris) was a French publicist, historian and Count of Montalembert, Deux-Sèvres.
He was an influential figure, and linked by friendship with the Catholic leaders of the time in France: Ozanam, Montalembert, Cochin, and especially Jean-Baptiste-Henri Lacordaire.
To the same period belongs the Légende de Notre-Dame (Paris, 1848), written under the influence of Montalembert.
What apparently gave rise to these accusations were the amicable relations established, principally through correspondence, between Victor de Buck and such men as Alexander Forbes, the learned Anglican bishop, and the celebrated Edward Pusey in England, Montalembert, and Bishop Félix Dupanloup in France and a number of others whose names were distasteful to many ardent Catholics.
