George Mercer Dawson CMG FRS FRSC (August 1, 1849 – March 2, 1901) was a Canadian geologist and surveyor. He was born in Pictou, Nova Scotia, the eldest son of Sir John William Dawson, Principal of McGill University and a noted geologist, and his wife, Lady Margaret Dawson. By age 11, he was afflicted with tuberculosis of the spine (Pott's disease) that resulted in a deformed back and stunted growth. Physical limitations, however, did not deter Dawson from becoming one of Canada's greatest scientists.
