The “bomb guru” for the terrorist group the Weather Underground never served a day in jail — but he did spend decades teaching in New York City classrooms, a new book reveals.
Ronald Fliegelman built explosives for the Weather Underground, a far-left group that launched a domestic bombing campaign in the 1960s and ’70s, including one explosion inside NYPD headquarters.
But when the group dissolved, Fliegelman managed to safely fade away into the square life. For 25 years, he worked as a public special-education teacher, retiring to a quiet life in Park Slope, Brooklyn, according to “Days of Rage: America’s Radical Underground, the FBI, and the Forgotten Age of Revolutionary Violence” (Penguin Press).
