LTC Woodward was an Army surgeon, specializing in use of the microscope [Henry pp36-41]. He was a native of Philadelphia [Henry p34]. He published an article describing the Army Medical Museum in Lippincott's Magazine in 1871 [Henry p60].
Woodward and Edward Curtis were the two physicians who performed the [head only] autopsy on President Lincoln. Woodward's report is reprinted in [Sotos].
"Back from Europe, Woodward suffered a broken legn on 1 January 1881, when his horse slipped and fell on him, but he was able to resume work at the [Army Medical] Museum in time to be one of the physician attending President James A. Garfield, when the President was shot and fatally wounded" [Henry p68]. Woodward recorded Garfield's autopsy.
Photo appears in [Henry pp15, 35].
