Source-derived summary

The Great Brain is a series of children's books by American author John Dennis Fitzgerald (1906–1988). Set in the small town of Adenville, Utah, between 1896 and 1898, the stories are loosely based on Fitzgerald's childhood experiences. Chronicled by the first-person voice of John Dennis Fitzgerald, the stories mainly center on the escapades of John's mischievous older brother, Tom Dennis Fitzgerald, a.k.a. "The Great Brain". The Great Brain was made into a movie released in 1978, with the main character played by Jimmy Osmond.

Mercer Mayer originally illustrated the books, except for 1995's The Great Brain Is Back (which was illustrated by Diane deGroat). Mayer did the original cover illustrations for the first seven books as well, but Carl Cassler re-did the cover illustrations for some of the reprints of the first seven books.

Background

Although John D. Fitzgerald was born in Price, Utah, several references in the stories suggest Adenville is located in Utah's "Dixie" in the southwestern corner of the state. A small village called Adenville briefly existed near Cedar City, about which little is known.

The publisher's note in The Great Brain Is Back, published after the death of the author, recounts the story of the series' origin.

Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as american series of children's books. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 22, 2026. The linked authority identifier is Q16156527. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1906, 1988, 1896 and 1898.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
