A prolific early 20th-century American writer, she is best remembered for the Letty Grey books and other stories for young readers. Her work grew out of a literary life shaped by family history in Des Moines, Iowa, and by a long, steady writing career.

by Helen Sherman Griffith
Helen Sherman Griffith (1873–1961) was an American author from Des Moines, Iowa. She was the daughter of Hoyt Sherman and Sara Sherman, and sources about her life connect her closely with Hoyt Sherman Place, where she was born and raised.
She is best known as the prolific author of the Letty Grey series, published by Penn Publishing Company of Philadelphia. In addition to children's fiction, records of her work show that she also wrote plays and other books, suggesting a career that ranged beyond a single series.
Though she is not as widely read today as some of her contemporaries, Griffith's books remain part of the long tradition of American girls' fiction from the early 1900s. Her writing still attracts interest from readers and libraries interested in classic juvenile literature.
