REMEMBERING leftist terror-bombing at the University of Wisconsin. 40 years ago today. “The blast killed UW research assistant Robert Fassnacht, leaving a wife and three children without their father…. Years of research were destroyed in the blast. Though the bomb was aimed at the Math research Center, it takes up only three floors of the building. The physics department occupied the basement and other offices in the new wing, and the astronomy department used the top floor and roof. The explosion reduced to tiny fragments the carefully ground mirrors in the two telescopes on the roof of Sterling Hall.”
