Brett L. Helquist (born in 1966) is an American illustrator best known for his work in the children's books A Series of Unfortunate Events. As such, his illustrations for that series have appeared in multiple media, including the books, the audio book covers, and the calendars.
Helquist was born in Ganado, Arizona, and grew up in Orem, Utah with his six sisters. As kids, they didn't go to many art museums. He says his love of art came from all the comic books he read. Helquist served as a Mormon missionary in Hong Kong, then earned a bachelor's degree in Fine Arts from Brigham Young University, and has lived in New York City since 1993. He has been published in the children's magazine Cricket, and the New York Times. He is represented by Steven Malk of Writers House in New York City.
Besides the thirteen A Series of Unfortunate Events books, Helquist has provided illustrations for several other children's books, including:
Helquist also wrote and illustrated Roger, the Jolly Pirate, , published in 2004.
He also produced new cover illustrations for a reprint of the 1954–1976 "Green Knowe" series by Lucy M. Boston (Harcourt, 2002; retaining the original interior illustrations by the writer's son Peter Boston):
