This negative was part of William Henry Fox Talbot's archive, which included photographs, correspondence, manuscripts and research notes. It was left to his son Charles Henry, who on his death, left its contents to his niece, Miss Matilda Gilchrist-Clark (1871-1958). In the 1934, she gave a large portion of this material to the then Science Museum and now the National Media Museum.
