Insulin: Boston and Toronto

Sent to and not published by Boston Globe Magazine; nor was any correction provided

No wonder Americans are so ill informed about the rest of the world.
In an article in Sunday's magazine about a young medical student, you said that he came to Boston where "insulin was introduced."
This gives the impression that Americans discovered, purified, and first treated diabetics with insulin.
Wrong!
This was the achievement of Banting, Best and Collip at the University of Toronto in Canada.
Please contribute to better informed Americans by publishing a correction next week.
Thank you.
