Born in New Ulm, Minnesota, Wanda Gág established herself as a prominent figure in American illustration and printmaking during the early 20th century. Her artistic formation was deeply influenced by her upbringing and her early dedication to documenting her life through detailed diaries, which were later published as Growing Pains.

Gág is celebrated for her distinct, rhythmic style in both her literary and visual work. She worked primarily in lithography and illustration, often infusing her children's books with a sense of movement and folk-inspired aesthetic. Her ability to integrate text and image set a standard for the modern picture book format.

Her legacy is cemented by numerous accolades, including multiple Newbery and Caldecott Honors. Her work continues to be recognized by major institutions, including the New York Public Library, which has highlighted her contributions to children's literature as enduring classics of the genre.
