Dr. David Graham Hall was born in 1858 in New Hampshire. Hall obtained a Harvard education and became a doctor, eventually setting up a practice in Dallas. This medical practice attracted attention that was controversial to say the least. Hall earned the nickname “Shooting Doctor” due to the large hypodermic needles he used. Additionally, there were incidents with an experimental typhoid vaccine that would turn the skin of patients blue. But it is not the medical practices of Dr. Hall that should be remembered, it is his charitable work.
