author
Best known for writing a short, lively biography of missionary Mary Slessor, this author appears in mid-20th-century Christian publishing with books aimed at general and younger readers. The surviving record is sparse, but the work that remains suggests a straightforward, accessible storytelling style.

by A. J. Bueltmann
A. J. Bueltmann is a little-documented author whose name survives mainly through a handful of older Christian books. Reliable catalog and bookseller records consistently connect the name with White Queen of the Cannibals: The Story of Mary Slessor of Calabar, a popular retelling of the life of missionary Mary Slessor, and with Take the High Road, published by Concordia Press in 1967.
Library and reader databases also point to several other titles under the same name, including books written for younger audiences. Because clear biographical sources about the author are hard to confirm, it is safest to say that Bueltmann seems to have written in a practical, readable style for faith-based and family readerships rather than to make stronger claims about personal background.
For modern listeners, Bueltmann is chiefly remembered for preserving an energetic missionary story in a compact, approachable form. Even with few personal details available, the author’s work has continued to circulate through reprints, library catalogs, and public-domain archives.
