|Known for||Jip and Janneke|
Sophia Maria "Fiep" Westendorp (17 December 1916 – 3 February 2004) was a Dutch illustrator who became popular due to her long collaboration with writer Annie M.G. Schmidt with their creation of Jip and Janneke.
Three generations of Dutch people have grown up with her illustrations. The drawings she made for Jip en Janneke, a series of stories which ran in Dutch newspaper Het Parool from 1953 to 1957, now adorn a variety of items sold by Dutch department store HEMA. Since the regular Dutch awards for illustrations always eluded her, she was given a unique award for her entire oeuvre in 1997. Westendorp also drew a text comic based on the Annie M.G. Schmidt story Tante Patent in the 1950s.
