Pierre Flandin (1778-1863), was born in Lyons, Rhône, Rhône-Alpes, France, son of Noel Flandin and Suzanne Mathevot.
In 1812, he married Marie-Charlotte Fortunee de Sèze (1795-1867), daughter of Madame de Sèze. They had seven children : two sons J. Eugene Flandin (1820-1870), who in 1858, married Louise Cruger (1835-1876), daughter of Major William E. Cruger; and five daughters, and also Henri Flandin (1824-) : Mathilde Flandin (1813-1908); Clara Flandin (1815-1908), who married Adele Lachathon de la Forest (1794-1869); Marie-Louise Flandin (1817-1894), who married George Pearce; Albertine A. Eveline de Seze Flandin (1821-1855), who married Charles Alphonse Lachathon de la Forest (1812-1884), Consul of France, and an officer who was awarded the Légion d'honneur; Fortunee de Seze Flandin (d. 1855), and Marie Adele Flandin (1830-1907), who, in 1862, married John Howland.
Flandin, a wealthy dealer, had three maids born in Ireland to manage his residence.
In 1823, he was a partner with Peter L. Van DerVoort, merchants, selling "Fancy & Staple Goods", in the firm of Vandervoort & Flandin, which was dissolved on March 22, 1823.
Flandin became a renowned New York City coin and art dealer. He was the art agent for John Trumbull, and John Lewis Krimmel.
Goldstein informs us : "Flandin's chief claim to fame was that one of his customers was Robert Gilmor, Jr., a Baltimore financier and the enthusiastic collector of not only old master paintings but also works by modern English and American artists. However, not all the pictures Flandin sold Gilmor had the pedigree that the dealer claimed for them. A "Holbein" for instance, eventually proved to be the work of Cornelius de Lyons, and a "Raphael" which Gilmor questioned even as he paid for it, the work of Jan Grossart." 
From 1833-1835, he was the treasurer of the American Academy of Fine Arts (founded in 1820).
He was an importer of art and antiques with a gallery on Broadway, New York City, New York. His residence was at 20 East 18th Street.
In June 1840, Flandin sued artist Mr. Baker, for a scandalous caricature drawn of the French Consul of New York engaging in a suggestive way with his two daughters, one married the Consul the following year.
In 1841, he was a founding member of the Brooklyn Institute and was a member of the Board of Directors. He donated paintings to their annual exhibition.
On March 21, 1855, his daughter Fortunee de Seze Flandin died.
On June 6, 1855, he sold his coin collection at Bangs, Brother & Company.
