Moina Mathers, born as Mina Bergson (28 February 1865 – 25 July 1928), was an artist and occultist at the turn of the 20th century. She was the sister of French philosopher Henri Bergson, the first man of Jewish descent to be awarded the Nobel Prize for Literature in 1927. She is, however, more known for her marriage to the English occultist, Samuel Liddell MacGregor Mathers, one of the founders of the organization Hermetic Order of the Golden Dawn and, after his death in 1918, for being the head of a successor organization, called the Rosicrucian Order of the Alpha et Omega.
Moina, then named Mina, or Minna, was born in Geneva, Switzerland, to a talented and influential Jewish family of Polish from father's and English and Irish from mother's sides, moving to Paris, when she was but two years of age. Her father, Michel Bergson, achieved some musical success in composing the operas Louisa de Montfort and Salvator Rosa, he was a native of Warsaw and member of the influential Bereksohn family. Moina Mathers' grandfather, Jacob Levison (born c. 1799) was a surgeon and a dentist. Her grandmother was Katherine Levison, born in London in c. 1800. Her maternal aunt was Minna Preuss, born in Hull, Yorkshire, in 1835, and her mother, Kate, née Levison, was also born in Yorkshire. Her eldest brother, Henri Bergson, 1859–1941, joined the faculty of the College of France and is best known for authoring the philosophical work Creative Evolution. He was also the president of the British Society for Psychical Research.
Moina was a talented artist and joined the Slade School of Art, at the age of fifteen. The Slade was known for encouraging young women in the Arts, at the turn of the nineteenth century. Moina was awarded a scholarship and four merit certificates for drawing at the School. She became friended with Beatrice Offor, with whome she shared a studio. It was also at the Slade in 1882, that Moina met her future friend Annie Horniman, who would become the major financial sponsor for the Matherses, as struggling artists and occultists, in backing the Hermetic Order of the Golden Dawn.
Moina met her husband, Samuel Liddell MacGregor Mathers, in 1887, while studying at the British Museum, where Samuel was a frequent patron. A year later, her future husband founded the Hermetic Order of the Golden Dawn, one of the most influential organizations in the Western Mystery Tradition. Moina was the first initiate of this Order in March, 1888. Her chosen motto in the Golden Dawn was ‘’Vestigia Nulla Retrorsum’’, meaning “Prudence never retraces its steps.” A year later in 1890, she married S.L. Mathers and Mina Bergson became Moina Mathers. In their occult partnership, her husband was described as the "evoker of spirits" and Moina as the clairvoyant "seeress", who often illustrated, as an artist, what her husband “evoked”. In March 1899, they performed the rites of the Egyptian goddess Isis, on the stage of the Theatre Bodiniere in Paris.
