1865–1919
A Danish-born mystic and astrologer, he became best known for shaping Rosicrucian ideas into books that reached a wide English-speaking audience. His work helped establish the Rosicrucian Fellowship in California in the early 20th century.
Born Carl Louis von Grasshoff in Aarhus, Denmark, Max Heindel later settled in the United States and became known as a writer, astrologer, and teacher of esoteric Christianity. He is most closely associated with the Rosicrucian Fellowship, a movement he founded to share what he called the Western Wisdom Teachings.
His best-known book, The Rosicrucian Cosmo-Conception (1909), brought together his ideas on spirituality, cosmology, and human development. Heindel wrote for readers who wanted religion, mysticism, and occult philosophy presented as a connected system, and his books remained influential in Rosicrucian and metaphysical circles after his death.
He died in Oceanside, California, on January 6, 1919. Though some details of his life are presented differently across sources, he is consistently remembered as an important early 20th-century popularizer of Rosicrucian and esoteric thought in America.
