SIR DAVID BRUCE (1855-1931) SIGNED QUOTE, “Yours truly, David Bruce, Madeira, 15th Feb. 1923”, on a card 4.25 x 3.5, by the Australian-born British pathologist and microbiologist who led the Malta fever commission that identified the organism that caused the fever. He was also on in South Africa investigating the outbreak of cattle disease which the natives called nagana, and in 1903 he identified the causative protozoan, and tsetse fly vector, African trypanosomiasis (“sleeping sickness”). He was a member of the Army Medical Services and eventually served as Commander of the Royal Medical College (1914-19) and retired as a Major-General. He published more than 97 technical articles, often co-authored by his microbiologist wife, Mary Elizabeth Bruce. The handwritten letter/quote, in full: “Dear Sir: If a Scotchman has any sentiment he carefully conceals it.” The card is in fine condition, with minor age toning.
