Description
This case was for a photograph of William Herschel's forty-foot telescope, which was the earliest known photograph on a glass negative. The image has deteriorated badly and is barely visible. Sir John Herschel (1792-1871), was an English astronomer, mathematician and chemist and son of Sir William Herschel. Herschel introduced 'hypo' (thiosulphate) as a photographic fixerative and discovered the cyanotype or blueprint process in 1842.
