Following Robert E. Howard's death, the courts granted his estate to his father, who continued to work with Howard's literary agent Otis Adelbert Kline. Dr. Isaac Howard passed the rights on to his friend Dr. Pere Kuykendall, who passed them to his wife, Alla Ray Kuykendall, and daughter, Alla Ray Morris. Morris left the rights to the widow of her cousin, Zora Mae Bryant, who gave control to her children, Jack Baum and Terry Baum Rogers. The Baums eventually sold their rights to the Swedish (now US) company Paradox Entertainment.
