Jean Antoine Auguste CHARNAL is an architect also known for his drawings and paintings. He is primarily active in the Rhône-Alpes region (formerly the historical and cultural province of Dauphiné). Jean Antoine Auguste was born in Lyon on March 2, 1803. He was the son of Jean-Pierre CHARNAL (1774-1836) and Antoinette MAILLON. The family lives in Sainte-Foy-lès-Lyon, a commune now included in the Lyon metropolitan area, where the maternal family comes from (the paternal family comes from the Jura). He entered the École des Beaux-Arts de Lyon on November 13, 1827, where he won several prizes. In 1844, he placed second in the competition organized by the Academic Society of Architecture for a project to beautify Place Bellecour in Lyon. Admitted as an architect on July 6, 1844, he worked as an archivist for this society from 1851 to 1862. Initially a professor of linear drawing at the Society for Elementary Instruction of the Rhone in 1847, he became its director in 1855, a position he held until his retirement in 1863. He died in 1871. On July 6, 1839, in Lyon, he married Pierrette Caroline GENOULAT (1816-1884), known as Lina, daughter of Jean-Pierre GENOULAT and Marie-Pierrette MARECHAL. It is very likely that Lina collaborated with her husband. Several drawings are known and bear the abbreviated name "Auguste CHARNAL, Architect." On the other hand, no work signed LINA CHARNAL is known, apart from a mention "Ve L. CHARNAL, rue de Lancry, 39" in Paris in the first edition of the Beaux-Arts directory, published in 1879. At that time, having become a widow, she lived with her son Jean Clément Raphael, who since his marriage in 1876 to his wife Marie GOUYON had lived at this address. On her death certificate, which occurred on June 15, 1884 in Nogent-sur-Marne, she is indicated to have been a painter.
