Harrie Irving Hancock (1868–1922) was an American chemist and writer who became a prominent figure in the landscape of late nineteenth and early twentieth-century popular literature. Balancing his scientific background with a prolific creative output, Hancock dedicated much of his writing career to producing engaging children's literature and juvenile fiction. His stories became staple reading for young audiences of his era, reflecting the themes and educational values of the period.
In addition to his extensive work in juvenile fiction, Hancock is remembered for his contributions to early speculative and invasion literature. He authored a notable fictional depiction of a German invasion of the United States, capturing the geopolitical anxieties of his contemporary society. Through these diverse literary endeavors, Hancock left a distinct mark as both a scientist and a storyteller before his passing in 1922.
