Comedy legend Lucille Ball had a long, successful career in entertainment. She was wildly popular for decades—performing on stage, in movies, and on television—but she is also remembered as a leading Hollywood producer in a time when few women held that role. Diana, Princess of Wales, was often called the “People’s Princess.” Raised by nobility, Diana married Charles, the Prince of Wales, but in time she became better known for her charitable efforts around the world. Biographies of these two, and many other influential women of the past century, are sure to fascinate readers of all ages.
