Charles Alden Seltzer (August 15, 1875 - February 9, 1942) was an American writer. He was a prolific author of western novels, had writing credits for more than a dozen film titles, and authored numerous stories published in magazines, most prominently in Argosy. Seltzer was born in Janesville, Wisconsin. Before becoming a successful writer, he was variously a newsboy, telegraph messenger, painter, carpenter and manager of the circulation of a newspaper, building inspector, editor of a small newspaper, and an appraiser.

Frank Hamilton Spearman (September 6, 1859 - December 29, 1937) was an American author. Spearman was known for his books in the Western fiction genre and especially for his fiction and non-fiction works on the topic of railroads. Although he wrote prolifically about railroads, his actual career was that of a bank president in McCook, Nebraska, and did not himself work for a railroad. Spearman was also a devout Roman Catholic convert and held political views best described as proto-Libertarian, both of which beliefs are also reflected in his novels.
