John Herschel, son of William Herschel, was born on March 7, 1792. He was one of the founders of the Royal Astronomical Society in Britain. Herschel was renowned for his work in astronomy, his books, his pioneering work in photography and his many contributions to science. When he died, he was given a state funeral and buried in Westminster Abbey not far from Isaac Newton.

Have you heard of blueprints? These are technical drawings and plans. We still call them blueprints even though modern ones aren't blue. However they were once blue because they were produced by a photographic process called cyanotype. It was invented by John Herschel in 1842. Here is a photograph Herschel himself took: Lady with a Harp

Astronomical photographs (and others!) used to be taken on glass. The great Palomar Sky Survey, for example, was made on glass plates. The oldest known photograph on glass still in existence was taken by John Herschel. It was a picture he took of William Herschel's famous 40-foot telescope.
