Victoria Holt
Eleanor Alice Burford was a prolific British author who wrote approximately 200 historical novels under multiple pen names, most famously Jean Plaidy, Victoria Holt, and Philippa Carr.
Her books sold millions of copies, with the Victoria Holt pseudonym alone achieving 56 million sales and Jean Plaidy selling 14 million by her death.
She adopted different names to distinguish between varying subject matters in her work.
Lesser-known pseudonyms included Eleanor Burford (her maiden name), Elbur Ford, Kathleen Kellow, and Ellalice Tate.
Many readers remained unaware that their favorite authors under different names were actually the same person, demonstrating her versatility across genres and styles.
