Moreau-Robert, Horticulteur, Angers, Bas Chemin du Mall, France. Culture spéciale de Rosiers.
[From
The Old Rose Adventurer, by Brent C. Dickerson, p. 41:] Maître-École is the name of an area in the city of Angers, in France, where several breeders had property: Coquereau had land there in the 1830s-1840s; Moreau-Robert had a
clos ("enclosure") there by 1866, perhaps handed down from his predecessors Vibert, Robert, and/or Robert & Moreau; later, ca. 1900, Chédane-Guinoisseau also owned property at Maître-École.
[Ibid, p. 522: Moreau-Robert] was founded by Monsieur Jean-Pierre Vibert, who brought it to Angers after having seen several seasons of his rose plantations ravaged by the white worm... The firm continued its work hybridizing and selling roses for another 30 years [after 1866]
