On the Campaign

In his Antietam after-action report, Gen Howard said:

In my brigade ... Colonel Wistar, Seventy-first Pennsylvania, with his right arm nearly useless from a former wound, had his left, disabled. He also was prompt and efficient."
He was disabled and left behind on the battlefield near the Dunker Church when the II Corps was overrun and retreated. Later in the day he got back through the Confederate lines, and got medical treatment at Keedysville.

After the war he made his fortune by financing railroad building. In 1892 he established the Wistar Institute of Anatomy and Biology in Philadelphia with gifts of $1 million.
