Heinrich Cornelius Agrippa von Nettesheim, 1486-1535, German mystic and alchemist.
Agrippa of Nettesheim was born of a once-noble family near Cologne, and studied both
                     medicine and law there, apparently without taking a degree. In 1503, he assumed the
                     name Cornelius Agrippa von Nettesheim, adopting the von to suggest a noble background;
                     three years later, he established a secret society in Paris devoted to astrology,
                     magic, and Kabbalah.
His career is diverse: secret agent, soldier, physician, orator, and law professor,
                     in Cologne, Paris, Dôle, London, Italy, Pavia, and Metz. In 1509, he set up a laboratory
                     in Dôle in the hopes of synthesizing gold, and for the next decade or so traveled
                     Europe, making a living as an alchemist, and conversing with such important early
                     humanist scholars as Colet and Reuchlin. In 1520, he set up a medical practice in
                     Geneva, and in 1524 became personal physician to the queen mother at the court of
                     King Francis I in Lyons. When the queen mother abandoned him, he began practicing
                     medicine in Antwerp, but was later banned for practicing without a license, and became
                     historiographer at the court of Charles V. After several stays in prison, variously
                     for debt and criminal offenses, he died in 1535.
Agrippa's wrote on a great many topics, including marriage and military engineering,
                     but his most important work is the three-volume De occulta philosophiae (written c.
                     1510, published 1531), a defense of "hidden philosophy" or magic, which draws on diverse
                     mystical traditions -- alchemy, astrology, Kabbalah. A later work, De incertitudine
                     et vanitate scientiarum (Of the Uncertainty and Vanity of the Sciences), attacks contemporary
                     scientific theory and practice.
Many of his opinions were controversial. His early lectures on theology angered the
                     Church, and his defense of a woman accused of witchcraft in 1520 led to his being
                     hounded out of Cologne Cologne by the Inquisition. In his own day, Agrippa was widely
                     attacked as a charlatan. After his death, legends about him were plentiful. Some believed
                     him to be not only an alchemist but a demonic magician, even a vampire. In one account,
                     he traveled to the New World.
In 1799, Robert Southey published an amusing ballad on this man, suggestive of his
                     later reputation as a master of black magic, as well as of his susceptibility to gothic
                     trappings. Percy Bysshe Shelley listed Agrippa and Paracelsus among his favorite writers
                     in a discussion with Godwin in 1812.
