Bobbsey Twins
Bobbsey Twins, fictional characters, two sets of fraternal twinsâthe older pair named Bert and Nan, the younger Freddie and Flossieâwho are featured in an extended series of childrenâs books by American author Laura Lee Hope (a collective pseudonym for many writers, including Harriet S. Adams). The characters made their first appearance in The Bobbsey Twins; or, Merry Days Indoors and Out (1904). Many of the early books from the original series (which eventually ran to more than 85) were revised in the 1950s and â60s, and many were reprinted. A second seriesâthe New Bobbsey Twinsâwas published from 1987 to 1992.
With Nancy Drew and the Hardy Boys, the Bobbsey Twins were among the most popular characters created by the Stratemeyer Literary Syndicate.
