Three Ways Canada Celebrated Insulin’s 100th Anniversary

The game-changing treatment for diabetes patients was marked with a special stamp and coin – and a Heritage Minute

A Stamp

This Canada Post stamp, unveiled in April, features an excerpt from Frederick Banting’s unpublished memoir and an original insulin bottle with its distinctive red cap. U of T researchers Scott Heximer and Patricia Brubaker worked with Canada Post and the Banting House National Historic Site to ensure the stamp’s historical accuracy and help source archival material.

A Heritage Minute

A Heritage Minute film, released in May, follows the journey of a young Leonard Thompson, who would become the first diabetes patient to be successfully treated with insulin – at Toronto General Hospital.

The decision to highlight the story of a single patient stemmed from a desire to emphasize the human element of the Nobel Prize-winning discovery, says Christopher Rutty, an adjunct professor at U of T’s Dalla Lana School of Public Health and one of three historical consultants on the team that created the 60-second clip. Alexandra Carter, science and medicine librarian at U of T’s Thomas Fisher Rare Book Library, says she was struck by the historical accuracy of the film’s visual details. “We have photos of the lab; it’s this shoddy-looking, cluttered space,” Carter says. “I love that they put that in.”

A Toonie

The Royal Canadian Mint issued a commemorative $2 coin, or “toonie,” in July. Designed by Ontario artist Jesse Koreck, the “tails” side of the coin features the laboratory tools – a vial, flask and mortar and pestle – that were used in the early formulation of insulin. The coin’s artwork also includes representations of the insulin molecule, red blood cells and glucose. A second version of the coin shows the molecule in blue – the same colour that is used to raise diabetes awareness.
