English: Provenance of the painting: The author William Henry Jackson (1843-1942) painted a painting (today known as Muddy Pond) in May-June, 1861, some weeks after Abraham Lincoln’s inauguration, and published the paining (showed to public generally) the same year. The author William Henry Jackson owned and kept the painting till his death on June 30, 1942. The author William Henry Jackson bequeathed the painting to his son-in-law Myron A. Pattison of Chevy Chase, Maryland; who granted the painting to Jackson’s daughters Harriet J. Pattison and Louise J. McLeod; who granted the painting to Jackson’s son Clarence S. Jackson in about September 1942; who sold the painting. It is not known where the painting was till August 1981; when likely Beatrice A. Grant (1924-2000) of Newton Massachusetts bought it and; in May 1999, she sold it as a painting of unknown author to Boris Karpachev of Newton Massachusetts; who discovered by March 2002 that some Jackson, the author of the painting, was actually William Henry Jackson (1843-1942); by 2005 Karpachev recognized the place (N 43º 37.769’; W 73º 00.171’), outlet of water from Muddy Pond of Rutland, Vermont, where 18-year old William Henry Jackson painted the painting from life; and by 2006 Karpachev restored the provenance of the painting as written above. Boris Karpachev is the current owner of the painting today-known as Muddy Pond and was the owner of the common-law copyright, if any, for the image of the painting. Boris Karpachev (user BCarpaccio) transferred his common-law copyright, if any, for the image of the painting to the public domain on February 14, 2006 by the fact of publishing the image of the painting Muddy Pond in English Wikipedia; because on September 24, 1941, Elwood P. Bonney had written about William Henry Jackson’s wish “to keep Clarence in bounds – to keep him under control”, and further: ”He seems to feel that Clarence will undoubtedly dispose of for cash everything he can get hold of without regard of his father’s wishes, particularly as to preservation of certain items by their disposition to proper Public Libraries, Historical Societies etc where they will be properly protected and of the value they will be in the future to students of history. He said his family never took any interest in his work from the historical view-point – or if there was any such interest it was very little.” (William Henry Jackson, Colorado History, Number 4, ISSN 1091-7438, Colorado Historical Society, 2000; p.139.)
