What artist is famous for the "Helga Pictures"?

Andrew Wyeth is the artist famous for the “Helga Pictures,” a large series of portraits and figure studies of Helga Testorf.

Wyeth began depicting Testorf in 1971 after meeting her near Kuerner Farm in Chadds Ford, Pennsylvania, where she worked as a nurse. Over roughly 15 years, he produced more than 200 works featuring her, using pencil, watercolor, drybrush, and tempera. The series explores her face, body, clothing, surroundings, and changing poses with Wyeth’s characteristic realism.

The pictures became widely known after a 1986 exhibition revealed the previously private body of work. Their discovery prompted public speculation about Wyeth’s relationship with Testorf, but the artistic significance of the series rests on its sustained study of one model and Wyeth’s process of repetition, revision, and observation.

A common mix-up is confusing the Helga Pictures with Christina’s World, Wyeth’s best-known single painting. Both are by Andrew Wyeth, but Christina’s World dates to 1948 and depicts Christina Olson, not Helga Testorf.
