William Edward Trevithick

William Edward Trevithick (1899 Kells, County Meath - 1958) was an Irish botanical illustrator who contributed some 60 botanical plates to Curtis’s Botanical Magazine. Belvoir Castle Trevithick was born while his father, William Edward Roberts Trevithick (1858–1929), was a gardener to Lord Headfort in his great estate near Kells. W. E. R. Trevithick was head gardener from 1912 to 1929 and established Headfort's arboretum. The younger William Edward Trevithick was a gardener at Headfort House from the age of 13, followed by employment at Belvoir Castle, next at the National Botanic Gardens, Glasnevin, and finally (beginning in 1920) at Kew, where he worked in the herbarium. He eventually left his position at Kew and became a commercial artist.

Trevithick produced illustrations for Flora of West Tropical Africa by John Hutchinson and John McEwen Dalziel, Flora Malesiana, and Curtis's Botanical Magazine.
