Herman Spöring Sr.

Herman Diedrich Spöring Sr. was a professor of medicine at the Royal Academy of Turku in Turku, Finland, and an amateur naturalist. One of his students was the Finnish scientist and priest Pehr Kalm. Spöring was one of the earliest scientists to propose, in 1747 shortly before his death, of the link between fish and tapeworms.
His son Herman Diedrich Spöring Jr., a Finnish explorer and botanist, was one of the scientific personnel who accompanied James Cook on the 1768-71 HM Bark Endeavour expedition to the Pacific.
