A most popular drawing master, Lesourd-Beauregard exhibited extensively at the Paris Salons, and was awarded a medal in 1842. He was a student of Gerard van Spaendonck, a renowned fruit and flower painter in France of the early 19th century. In 1840 Lesourd-Beauregard became Professor of Botanical Drawing at the Musée d'Histoire Naturelle, replacing well-known artist and teacher, Pierre-Joseph Redouté.
Les Eglantines reveals the strong influence of Gerard van Spaendonk. As one of the few flower painters proficient in oil during this period, Lesourd-Beauregard's analytical approach to this painting and his superb eye for refined detail produced a lovely and exacting study.
Les Eglantines was originally part of a large French estate, from which two other Lesourd-Beauregard paintings were recently sold at auction. The Sotheby's sale, entitled "Revolution in Art" (January 2002) included two Lesourd-Beauregard oils of similar size, which sold for $16,800 and $21,450 respectively.
