"Historians of medicine and alchemy have long ago demonstrated that Paracelsian medicine, although in terms of healing craft no improvement, helped to pave the way away from the humoral medicine of antiquity to modern scientific medicine and that the Paracelsian chemists laid the foundations for both chemical pharmacology and chemistry. Fludd was the leading Paracelsian physician in Britain in the first half of the seventeenth century. Fludd was also an independent co-inventor of the thermoscope the predecessor of the thermometer. Lastly Fludd was a close friend and colleague of William Harvey and was the first to accept and publicly support Harvey theory of the blood circulation. He even helped Harvey to get his De mortu cordis published by his printers in Germany."
