Mary Karadja, Swedish writer, spiritualist and princess (born 1868)

Marie Louise "Mary" Karadja was a Swedish writer, spiritual medium and aristocrat, a central figure in Western esotericism during the Belle Époque. Born in Stockholm to the business magnate Lars Olsson Smith, she married prince Jean Karadja Pasha, an Ottoman diplomat, with whom she had a son, the Romanian diplomat and scholar Constantin Karadja. She lived in various European countries, and published works in several languages—beginning with aphorisms in French. Her involvement with Kardecist spiritism dates to 1899, and was prompted by the deaths of an infant son and of her husband the prince. Under the influence of spiritism, Theosophy and neo-gnosticism, the princess produced spirit drawings and writings that she stated were inspired and dictated to her spiritually. She was a literary celebrity in her native country for a while, and corresponded with August Strindberg; she was also heavily criticized for her claims by investigators such as Henry Morselli and Joseph McCabe, and was a regular target of Birger Sjöberg's satirical articles.
