author
A writer for young readers, she is best known for a warm, observant story set on the Maine coast during World War II. Her work has been preserved by Project Gutenberg, where modern readers can still discover Over Periscope Pond.

by Marjorie Crocker, Esther Sayles Root
Marjorie Crocker was an American author whose work is now in the public domain and available through Project Gutenberg. The clearest confirmed connection I found is her authorship of Over Periscope Pond, a novel for younger readers.
That book is set in coastal Maine during World War II and blends everyday life, family feeling, and wartime tension in an accessible way. The setting and tone suggest a writer interested in how large events shape ordinary communities, especially through the eyes of children.
Reliable biographical detail about her life appears to be scarce in the sources I could confirm, so it is better to keep the focus on the work itself rather than overstate the record. For listeners who enjoy vintage children's fiction with a strong sense of place, her writing offers a small but memorable window into its era.
