2.5x3.25 B&W vintage photograph signed on the lower margin by Harriet Adams in black ink. Excellent condition. (1892-1982) Harriet Stratemeyer Adams was an American juvenile book packager, children's novelist, and publisher who was responsible for some 200 books over her literary career. She wrote the plot outlines for many books in the Nancy Drew series, using characters invented by her father, Edward Stratemeyer. Adams also oversaw other ghostwriters who wrote for these and many other series as a part of the Stratemeyer Syndicate and rewrote many of the novels to update them starting in the late 1950s.The extremely popular Nancy Drew books were the brainchild of Adams's father, who created the characters of a sixteen-year-old sleuth, her lawyer father, and their housekeeper. Later, Nancy's age was increased to eighteen to give her more independence. Adams came up with plot ideas and hired ghostwriters to flesh them out. The best-known books were written primarily by Mildred Wirt Benson, all published under the pseudonym Carolyn Keene. Adams outlined a few in the Hardy Boys series, which were published under the pseudonym Franklin W. Dixon. Although Adams claimed to have written all the Nancy Drew books entirely by herself during her lifetime, it is well established that Wirt and 28 other authors did the actual writing, following Adams's ideas and embellishing them. Adams touched up the completed manuscripts.This lot came from the Jim Wiggins collection we purchased in July 2022.
