Sir William Jackson Hooker was an English botanist and botanical illustrator, who became the first director of Kew when in 1841 it was recommended to be placed under state ownership as a botanic garden. At Kew he founded the Herbarium and enlarged the gardens and arboretum. The standard author abbreviation Hook. is used to indicate this person as the author when citing a botanical name.

The Royal Guelphic Order, sometimes referred to as the Hanoverian Guelphic Order, is a Hanoverian order of chivalry instituted on 28 April 1815 by the Prince Regent. It takes its name from the House of Guelph, of which the Hanoverians were a branch. Since Hanover and the United Kingdom shared a monarch until 1837, the order was frequently bestowed upon British subjects.
