author
b. 1880
Best remembered for a charming early-1900s picture book, this little-known author and illustrator turned classic nursery-rhyme play into a world of teddy bears. The surviving record is slim, which gives the work an old-library mystery of its own.

by Frederick Leopold Cavally
Frederick Leopold Cavally is an elusive figure in the historical record, but library and archive listings identify him as born in 1880 and credit him with Mother Goose's Teddy Bears, published in 1907 by Bobbs-Merrill.
That book reimagines familiar Mother Goose material with teddy bears at the center, placing Cavally in the playful, picture-book world of early 20th-century children's publishing. Some modern reprints and catalog entries also describe him as the book's illustrator, suggesting he may have shaped both the words and the visual charm readers remember.
Beyond that, confirmed biographical details are scarce. No reliable portrait was found during this search, so the book itself remains the clearest window into his work and style.
