A man in San Antonio looks up at an agave flower, 1889. I love so many things about this, especially the man's dapper hat, the bonnet on the woman in the background, and that great agave. Agaves are my spirit plant. From the Austin History Center via the Portal to Texas History.
This is James Harrison.
When he was 18, he learned that his blood contained an antibody that could treat a rare blood disease in infants. He donated blood every week for the next 60 years.
By the time he was done, he'd saved more than 2.4 million lives.
