Dr. William Sansum in his lab where he produced insulin.

The first dose of insulin ever manufactured in the U.S. was given to Charles Cowan in Santa Barbara, administered by Dr. Sansum.

why we are celebrating:

Sansum Diabetes Research Institute’s founder, Dr. William Sansum, was the first physician in the United States to manufacture and administer insulin in the treatment of diabetes 100 years ago here in Santa Barbara on May 31, 1922. 
Dr. Sansum’s extraordinary accomplishment ensured that diabetes was no longer a death sentence and forever changed the way this disease is managed. With your support, SDRI will further our mission of providing research, education, and care to those impacted by diabetes–both locally and globally.
