'the best of the chronic diseases' because it was 'clean, seldom unsightly,
not contagious, often painless and susceptible to treatment.' |

significant for the revolution in diabetes therapy that developed from it. |

of Diabetes, citing exhaustive case records of 76 of the 100 diabetes
patients he observed, becomes the director of diabetes research at the
Rockefeller Institute. |
| 1919-20 |
· Allen establishes the first treatment clinic in the
USA, the Physiatric Institute in New Jersey, to treat patients with
diabetes, high blood pressure and Bright's disease; wealthy and desperate
patients flock to it. |
| July 1, 1920 |

| October 31, 1920 |
· Dr. Banting conceives of the idea of insulin after
reading Moses Barron's 'The Relation of the Islets of Langerhans to Diabetes
with Special Reference to Cases of Pancreatic Lithiasis' in the November

the assistance of Best, Collip and Macleod, Dr. Banting continues his
research using a variety of different extracts on de-pancreatized dogs. |

with insulin. |
