He was born at Parkgate, Wirral, England, the son of Rev. Algernon Sidney Grenfell, headmaster of Mostyn House School, and Jane Georgiana Hutchison and married Anne Elizabeth Caldwell MacClanahan of Chicago, Illinois, in 1909. She died in 1938. They had three children and retired to Vermont after his work in Newfoundland.
Medical education and mission work 
Grenfell moved to London in 1882. He then commenced the study of medicine at the London Hospital Medical College (now part of Barts and The London School of Medicine and Dentistry) under the tutelage of Sir Frederick Treves: he graduated in 1888.
The Royal National Mission to Deep Sea Fishermen sent Grenfell to Newfoundland in 1892 to improve the plight of coastal inhabitants and fishermen. That mission began in earnest in 1893 when he recruited two nurses and two doctors for hospitals at Indian Harbour, Newfoundland and later opened cottage hospitals along the coast of Labrador. The mission expanded greatly from its initial mandate to one of developing schools, an orphanage, cooperatives, industrial work projects, and social work. Although originally founded to serve the local fishermen the mission developed to include the aboriginal peoples and settlers along the coasts of Labrador and the eastern side of the Great Northern Peninsula of northern Newfoundland. For his years of service on behalf of the people of these communities he was later knighted. He had two sons and a daughter. Grenfell died of a coronary thrombosis at Kinloch House on 9 October 1940, and his ashes were brought to St Anthony, where they were placed inside a rock face overlooking the harbour.
Introduction of reindeer 
In 1907 Grenfell imported a group of 300 reindeer from Norway to provide food and serve as draft animals in Newfoundland. Unbeknownst to him, some of the animals carried a parasitic roundworm, Elaphostrongylus rangiferi, that then spread to native caribou herds. The reindeer herd eventually disappeared; however, the parasite took hold and causes cerebrospinal elaphostronglyosis (CSE) in caribou, a disease well known in reindeer in Scandinavia.
International Grenfell Association 
By 1914 the mission had gained international status. In order to manage its property and affairs, the International Grenfell Association, a non-profit mission society, was founded to support Grenfell's work. The Association operated, until 1981, as an NGO. It had responsibility for delivery of healthcare and social services in northern Newfoundland and Labrador. After 1981 a governmental agency, The Grenfell Regional Health Services Board, took over the operational responsibility. The International Grenfell Association, having divested itself of all properties and operational responsibility for health and social services, boarding schools, hospitals then became a supporting association making grants and funding scholarships for medical training.
Historical Society 
The Sir Wilfred Thomason Grenfell Historical Society was formed in 1978. The society purchased Grenfell's home in St. Anthony, Newfoundland and Labrador. The home has been restored as a museum and archives. The Sir Wilfred Thomason Grenfell Historical Society with the support of Provincial Government and the International Grenfell Association began construction of an interpretation centre in St. Anthony and it was opened in 1997. This facility added to the existing house and serves to promote the legacy to thousands of visitors each year. The Grenfell Interpretation Centre also is used by other organizations for meetings and events. A large interpretive display is housed there and provides historical background surrounding the work of Sir Wilfred Thomason Grenfell.
Literary inspiration 
A unique figure, Grenfell served to inspire at least two characters in Canadian literature: Dr. Luke in Norman Duncan's Doctor Luke of the Labrador (1904) and Dr. Tocsin in White Eskimo by Harold Horwood (1972).
The following statement has been widely ascribed to him, but cannot be found in any of his books: "The service we render to others is really the rent we pay for our room on this earth. It is obvious that man is himself a traveler; that the purpose of this world is not 'to have and to hold' but 'to give and serve.' There can be no other meaning."
