Burchard Kranich

Burchard Kranich (c. 1515–1578) (also known as Doctor Burcot) was a mining engineer and physician who came to England from Germany. He was involved in mining ventures in Derbyshire and Cornwall, and in assaying the black ore, thought to be gold-bearing, brought back to England from Baffin Island by Martin Frobisher. He later practised as a physician in London, where he enjoyed a mixed reputation, and is said to have attended Elizabeth I when she contracted smallpox. He is alluded to in several literary works published during the reigns of Elizabeth I and James I.
