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.

"It was high noon in the desert, but there was no dazzling sunlight. Over the earth hung a twilight, a yellow-pink softness that flushed across the sky like the approach of a shadow, covering everything yet concealing nothing, creeping steadily onward, yet seemingly still, until, pressing low over the earth, it took on changing color, from pink to gray, from gray to black-gloom that precedes tropical showers. Then the wind came-a breeze rising as it were from the hot earth-forcing the Spanish dagger to dipping acknowledgment, sending dust-devils swirling across the slow curves of the desert-and then the storm burst in all its might. For this was a storm-a sand-storm of the Southwest."
