Heinrich Khunrath (c. 1560 – 9 September 1605), or Dr. Henricus Khunrath as he was also called, was a German physician, hermetic philosopher, and alchemist. Frances Yates considered him to be a link between the philosophy of John Dee and Rosicrucianism. His name, in the spelling "Henricus Künraht" was used as a pseudonym for the 1670 publisher of the Tractatus Theologico-Politicus of Baruch Spinoza.
