About the author

Born in Plainfield, New Jersey, in 1903, Albert Capwell Wyckoff later lived in Elizabeth and attended the Pingry School. After his father died while he was still in school, he had to leave before graduating and went to work, first for Standard Oil and later as a switchboard operator at the Federal Reserve Bank of New York.

While working nights, he taught himself to type and began writing. That effort grew into a substantial career in juvenile fiction, especially the Mercer Boys series and the Mystery Hunter series. He also wrote Christian books and drew on his own experiences for nonfiction, including The Challenge of the Hills, a book connected to his missionary work in the Ozarks.

Wyckoff was also an ordained minister in the Presbyterian Church and spent years in missionary and church work in Arkansas and Kentucky. His life joined practical hardship, religious service, and popular storytelling, helping explain why his books often feel both adventurous and grounded.
