1. Frederick Banting (1891 - 1941)

With an HPI of 66.04, Frederick Banting is the most famous Canadian Physician.  His biography has been translated into 72 different languages on wikipedia.

Sir Frederick Grant Banting (November 14, 1891 – February 21, 1941) was a Canadian pharmacologist, orthopedist, and field surgeon. For his co-discovery of insulin and its therapeutic potential, Banting was awarded the Nobel Prize in Physiology or Medicine with John Macleod. Banting and his student, Charles Best, isolated insulin at the University of Toronto in the lab of Scottish physiologist John Macleod. When he and Macleod received the 1923 Nobel Prize in Physiology or Medicine, Banting shared the honours and award money with Best. That same year, the government of Canada granted Banting a lifetime annuity to continue his work. To this day, Frederick Banting, who received the Nobel Prize at age 32, remains the youngest Nobel laureate for Physiology/Medicine.

2. Oswald Avery (1877 - 1955)

With an HPI of 62.80, Oswald Avery is the 2nd most famous Canadian Physician.  His biography has been translated into 35 different languages.

Oswald Theodore Avery Jr. (October 21, 1877 – February 20, 1955) was a Canadian-American physician and medical researcher. The major part of his career was spent at the Rockefeller Hospital in New York City. Avery was one of the first molecular biologists and a pioneer in immunochemistry, but he is best known for the experiment (published in 1944 with his co-workers Colin MacLeod and Maclyn McCarty) that isolated DNA as the material of which genes and chromosomes are made. The Nobel laureate Arne Tiselius said that Avery was the most deserving scientist not to receive the Nobel Prize for his work, though he was nominated for the award throughout the 1930s, 1940s, and 1950s. The lunar crater Avery was named in his honor.

Charles Brenton Huggins (September 22, 1901 – January 12, 1997) was a Canadian-American surgeon and physiologist known for his work on prostate function, prostate cancer, and breast cancer. Born in Halifax in 1901, Huggins moved to the United States for medical school. He was one of the founding staff members of the University of Chicago Medical School, where he remained for the duration of his professional research career. Huggins' work on how sex hormones influence prostate function ultimately led to his discovery of hormone therapies to treat prostate cancer. For this finding, he was awarded the 1966 Nobel Prize for Physiology or Medicine. In addition to his work on prostate cancer, Huggins explored the relationship between hormones and breast cancer, developed an animal model for breast cancer, and developed "chromogenic substrate"s that are widely used for biochemical analyses. Huggins continued to perform research into his 90s; he died in Chicago in 1997.

Bethune came to international prominence first for his service as a frontline trauma surgeon supporting the Republican government during the Spanish Civil War, and later supporting the Chinese Communist Party's (CCP) Eighth Route Army during the Second Sino-Japanese War. Bethune helped bring modern medicine to rural China, treating both sick villagers and wounded soldiers. Bethune was responsible for developing a mobile blood-transfusion service for frontline operations in the Spanish Civil War. He later died of blood poisoning after accidentally cutting his finger while operating on wounded Chinese soldiers. Bethune's service to the CCP earned him the respect of Mao Zedong, who wrote a eulogy dedicated to Bethune when he died in 1939. His name is honored in China to this day.

In addition to being a physician he was a bibliophile, historian, author, and renowned practical joker. He was passionate about medical libraries and medical history, having founded the History of Medicine Society (formally "section"), at the Royal Society of Medicine, London. He was also instrumental in founding the Medical Library Association of Great Britain and Ireland, and the (North American) Association of Medical Librarians (later the Medical Library Association) along with three other people, including Margaret Charlton, the medical librarian of his alma mater, McGill University.
