Book Notes

The Discovery of Insulin book cover

When I read a book I have the habit of highlighting certain passages I find interesting or useful. After I finish the book I’ll type up those passages and put them into a note on my phone. I’ll keep them to comb through every so often so that I remember what that certain book was about. That’s what these are. So if I ever end up lending you a book, these are the sections that I’ve highlighted in that book. Enjoy!

The only good use of patents I’ve seen to date – The University of Toronto patented the process of developing insulin to control the quality of insulin sold to diabetics.

Diabetes seems to be brought on by a variety of factors. It is most commonly found in people over fourty whose metabolic system has had to work hard during their lives to cope with over-nourishment leading to obesity.

The press made a mess of the discovery. Just another reminder that the media and the press can’t be trusted for reliable information. Don’t read headlines when things are happening, the journalists usually don’t have the public’s best interest top of mind. The only way to get reliable info is a look back in time after the frenzy has passed.

After the discovery, President Falconer of the university dismissed the anti-vivisectionists, surely some of history’s most misguided idealists, with the comment, “Why, these people simply don’t understand what the word humanity means.”

Banting and Best alone did not discover insulin. Their work was part of the discovery of insulin.

The other view, following Darwin’s maxim of credit going to to man who convinces the world…

Some students are simply impossible to deal with. Macleod could have done better, but only Superman could have guided Banting to insulin without major troubles.

They did not realize that those who understood history would eventually come to honor all of them.
