Biography
Biography
His work was regularly exhibited at the American Art-Union from 1846 to 1852. An 1848 distribution record shows that five of his paintings had been distributed by the American Art-Union by 1848, a high proportion compared to other artists. The artist appears to have lived in New York all his life. His name is recorded in connection with the Broadway Tabernacle Church in 1844. New York city directories and censuses show that Leonori lived in various locations in the city from 1871 to 1891. Robert Leonori's wife, née Margaret S. Hatfield, was a descendant of the Hatfield Family of Elizabeth, New Jersey. The couple married in Essex, New York, on 8 May 1841 with the marriage register showing that the artist was a New York resident in that year. Robert Leonori died in 1905 in New York City. Leonori's works have rarely appeared at auctions. In 2000, his Seascape - Bull's Creek, New Jersey, fetched $6,325 with Buyer's Premium, at Christies NY, while a view of Niagara Falls, fetched $3,000 (Lot 188) on 14 December 2005 at Sotheby's New York. A descendant of Robert G. Leonori, Barbara Peterson (second time great granddaughter) donated works by the artist in 2014 to the Mountainside Restoration Committee responsible for Deacon Andrew Hetfield House, Union County, New Jersey.
