author
Best known for co-creating gentle early-20th-century children's stories, this writer helped bring Charlie's everyday adventures—and a memorable ship's cat named Galley Jack—to young readers. Her books have a warm, old-fashioned charm centered on animals, friendship, and childhood curiosity.

by Helen Hill, Violet Maxwell
Violet Maxwell is credited as the co-author, and in some editions co-illustrator, of several children's books with Helen Hill. Confirmed titles include Charlie and His Puppy Bingo (published in 1923 by The Macmillan Company), The Adventures of Galley Jack, Ship's Cat to the "Susan P. Meservey" (1929), and Little Tonino.
The surviving catalog and book records suggest that her work was aimed at young readers and often built around animals and adventure. Charlie and His Puppy Bingo follows a small child's delight in getting a puppy, while Galley Jack shifts to a more nautical setting with a ship's cat at the center.
Reliable biographical details about Maxwell herself appear to be scarce in the sources I could confirm. I was able to verify her authorship through library, catalog, and public-domain book records, but I could not confidently confirm fuller personal details such as birth dates, places, or a portrait image.
