This excellent portrait, from a steel plate engraving, is of Connecticut-born physician Charles Squire Wood, who was Assistant Surgeon of the 66th New York Infantry and treated wounded soldiers on the field after Antietam in September 1862.

This copy is from the Images from the History of Medicine (IHM) collection at the National Library of Medicine. There’s one for sale on eBay, if you hurry.
