As well as astronomy, Herschel also made great advances in the field of photography. He developed a fixative for use with silver-based photographs, techniques for making photographs in colour and on glass plates, and was also the first person to use the terms 'positive', 'negative', 'snapshot' and 'photographer'.
In 1850, Herschel became Master of the Royal Mint, a position which he held until 1855, and in that time he oversaw a major reform of the Mint.
John Herschel died in 1871, and was buried in Westminster Abbey, next to Sir Isaac Newton. |
