James Fenimore Cooper (1789 – 1851) was a prolific and popular American writer of the early 19th century. His historical romances of frontier and Indian life in the early American days created a unique form of American literature. Before embarking on his career as a writer he served in the U.S. Navy as a Midshipman, which greatly influenced many of his novels and other writings. The novel that launched his career was "The Spy", set during the Revolutionary War and published in 1821. He also wrote numerous sea stories and his best-known works are five historical novels known as the "Leatherstocking Tales". Though some scholars have hesitated to classify Cooper as a strict Romantic, Victor Hugo pronounced him greater than the great master of modern romance. This verdict was echoed by a multitude of less famous readers, such as Balzac and Rudolf Drescher of Germany, who were satisfied with no title for their favourite less than that of the "American Scott." The modern mass-market romance genre was born in America 1972 with Avon's publication of Kathleen Woodiwiss's historical romance "The Flame and the Flower". Set around 1900. it is the first romance novel "to [follow] the principals into the bedroom." Aside from its content, the book was revolutionary in that it was one of the first single-title romance novels to be published as an original paperback, rather than being first published in hardcover, and, like the category romances, was distributed in drug stores and other mass-market merchandising outlets. The novel went on to sell 2.35 million copies. Avon followed its release with the 1974 publication of Woodiwiss's second novel, "The Wolf and the Dove" and two novels by newcomer Rosemary Rogers. One of Rogers's novels, "Dark Fires" sold two million copies in its first three months of release, and, by 1975, "Publishers Weekly" had reported that the "Avon originals" had sold a combined 8 million copies.
