The Winchester Medical College (WMC) building, currently located at 302 W. Boscawen Street, Winchester, Virginia, along with all its records, equipment, museum, and library, was burned on May 16, 1862, by Union troops occupying the city. This was "retaliation for the dissection of cadavers from John Brown's Raid". More specifically, it was in retaliation for the desecration they discovered of one of those cadavers, the body of one of John Brown's sons, identified years later as Watson. The body of John Brown's son, fighting against slavery in the raid on Harpers Ferry, had been dishonored: made into an anatomical specimen in the College's museum, with the label "Thus always with Abolitionists". In addition, students at the school collected and then dissected the bodies of three other members of Brown's troop and a black boy was apparently tortured and killed there for favoring the Union.

Watson Brown was a son of the abolitionist John Brown and his second wife Mary Day Brown, born in Franklin Mills, Ohio. He was married to Isabell "Belle" Thompson Brown, and they had a son Frederick W., who died of diphtheria at age 4, and is buried at what is now the John Brown Farm State Historic Site in North Elba, New York.
