In January 1837, the Brothers of the Christian Schools opened a boarding school for boys at 165Rue du Faubourg Saint-Martin, which they transferred on 8 April 1839 to Passy (at the time a commune on the outskirts of Paris), in specially-built facilities and ones of the allotted Hôtel de Valentinois which they had possibly preserved.[1][a] In the following decades, the Brothers rebuilt some of the school's facilities and expanded other ones, as the number of boarders kept growing, despite a decrease during the French Revolution of 1848.[6] The school buildings bordered eventually, if not from the day of its opening in Passy, all of the segment of present-day Rue Raynouard running from the corner of present-day Rue Singer to that of Rue des Vignes.
On 18 March 1864, the school (having over 700 pupils then) was visited by Minister of EducationVictor Duruy, who complimented the Brothers "in the most flattering terms upon the appearance and tendency of the pensionnat".[7] Another ministerial visit took place on 12 May of the same year,
caused by the resistance to the projet de loi for special instruction[b] which was manifested in the parliamentary commission which had been appointed to examine the subject. To overcome this opposition M. Duruy invited the members of the commission to accompany him to Passy, in order to demonstrate to them, as he expressed it, the successful realization of his project by the Christian Brothers.[7]
As a law of 7 July 1904 prevented religious congregations from teaching any longer, the Brothers moved their boarding school's residence to Froyennes, Belgium in 1905.[9] They would be selling off approximately three quarters of the boarding school's buildings in Passy.[10][c] An association of fathers took advantage of the ones unsold yet disused to recreate a school, which was granted diocesan tutelage by Archbishop Léon-Adolphe Amette in 1911,[10] and became known as "le Pensionnat diocésain de Passy".
^Auguste Doniol's claim that they had bought "les deux pavillons" (supposedly those bordering present-day Rue Raynouard), and a part of the gardens, from "M. Briant" in June 1837[2] possibly conflicts with Henri Bouchot's claim that Briant had owned "the back premises" (likely the orangery and adjoined buildings) "and kitchen-garden", while "the greater part, the house with the colonnades, the terraces and garden" had been owned by "writer and politician, Claude Fulchiron of Lyons",[3] and with claims that these passed in 1811, at least in part, to banker Isaac-Louis Grivel's daughter Anne-Marie, and were sold by her husband Charles Vernes to the Brothers in 1836,[4] another part having been bought by industrialist David Singer and opened with a street bearing his name as early as 1836.[5]
