The Wisconsin Historical Society writes that this day in 1970 marks the anniversary of a 1970 bombing:
1970 – Sterling Hall Bombing on UW-Madison Campus
On this date a car bomb exploded outside Sterling Hall, killing research scientist Richard Fassnacht. Sterling Hall was targeted for housing the Army Mathematics Research Center and was bombed in protest of the war in Vietnam. The homemade bomb (2,000 pounds of ammonium nitrate soaked in aviation fuel) was detonated by the New Year’s Gang, aka Vanguard of the Revolution, who demanded that a Milwaukee Black Panther official be released from police custody, ROTC be expelled from the UW campus, and “women’s hours” be abolished on campus. The entire New Year’s Gang fled to Canada the evening of the explosion. Four men were charged with this crime: Karleton Armstrong, David Fine, Dwight Armstrong, and Leo Burt. All but Burt were captured and served time for their participation. Leo Burt remains at large.[Source: On Wisconsin (online PDF) Summer 2005]
