Which of these scientists was an advisor to Queen Elizabeth I?

John Dee (13 July 1527 – 1608 or 1609) was an Anglo-Welsh mathematician, astronomer, astrologer and occult philosopher, and an advisor to Queen Elizabeth I. He spent much time on alchemy, divination, and Hermetic philosophy. He also advocated turning England's imperial expansion into a "British Empire", a term he is generally credited with coining.

To 21st-century eyes, Dee's activities straddle the worlds of magic and modern science, but the distinction would have meant nothing to him. He was invited to lecture on Euclidean geometry at the University of Paris while still in his early twenties. He was an ardent promoter of mathematics, a respected astronomer and a leading expert in navigation, who trained many who would conduct England's voyages of discovery.
