author
Known for the children’s novel Pearl and Periwinkle, this early 20th-century writer is remembered today mainly through public-domain editions that have kept the book in circulation. Her work centers on orphaned siblings, family ties, and gentle domestic adventure.

by Anna Graetz
Very little biographical information about Anna Graetz could be confirmed from reliable sources available during this search. She is clearly credited as the author of Pearl and Periwinkle, a children’s novel that was published in 1917 and is now available through Project Gutenberg.
The novel follows two orphaned siblings sent to live with their aunt, blending everyday family life with warmth, mischief, and reconciliation. That surviving work suggests a writer interested in childhood, home, and the emotional turns of ordinary life.
Because dependable personal records were not easy to verify, it is best to treat Anna Graetz as an obscure author whose legacy rests chiefly on this one preserved book rather than on a well-documented public biography.
