William Thomas Stearn (; 16 April 1911 – 9 May 2001) was a British botanist. Born in Cambridge in 1911, he was largely self-educated and developed an early interest in books and natural history. His initial work experience was at a Cambridge bookshop, but he also had a position as an assistant in the university botany department. At the age of 29 he married Eldwyth Ruth Alford, who later became his collaborator, and he died in London in 2001. While at the bookshop, he was offered a position as a librarian at the Royal Horticultural Society in London (1933–1952). From there he moved to the Natural History Museum as a scientific officer in the botany department (1952–1976). After his retirement, he continued working there, writing, and serving on a number of professional bodies related to his work, including the Linnean Society, of which he became president. He also taught botany at Cambridge University as a visiting professor (1977–1983). Stearn is known for his work in botanical taxonomy and botanical history, particularly classical botanical literature, botanical illustration and for his studies of the Swedish scientist Carl Linnaeus. His best known books are his Dictionary of Plant Names for Gardeners, a popular guide to the scientific names of plants, and his Botanical Latin for scientists. Stearn received many honours for his work, at home and abroad, and was made a Commander of the Order of the British Empire (CBE) in 1997. Considered one of the most eminent British botanists of his time, he is remembered by an essay prize in his name from the Society for the History of Natural History, and a named cultivar of Epimedium, one of many genera he produced monographs on. He is the botanical authority for over 400 plants that he named and described. Life Childhood William Thomas Stearn was born at 37 Springfield Road, Chesterton, Cambridge, England, on 16 April 1911, the eldest of four sons, to Thomas Stearn (1871 or 1872–1922) and Ellen ("Nellie") Kiddy (1886–1986) of West Suffolk. His father worked as a coachman to a Cambridge doctor. Chesterton was then a village on the north bank of the River Cam, about two miles north of Cambridge's city centre, where Springfield Road ran parallel to Milton Road to the west. William Stearn's early education was at the nearby Milton Road Junior Council School (see image). Despite not having any family background in science (though
