Sandra Wallus Sammons moved from Pennsylvania to Florida and became an elementary school librarian in Lake County. Learning of the dearth of books on Florida history aimed at fourth graders, she began writing biographies of Floridians who lived fascinating, inspirational lives. She wrote Marjory Stoneman Douglas and the Florida Everglades, Marjorie Kinnan Rawlings and the Florida Crackers, The Two Henrys: Henry Plant and Henry Flagler and Their Railroads, and Henry Flagler, Builder of Florida.
