Columbia Administration, along with five other anti-war students (including Rudd), for demonstrating inside Low Library to protest Columbia University's institutional sponsorship of the Pentagon's Institute for Defense Analyses weapons research think-tank. To protest the Columbia Administration's repression of "The IDA Six", on April 23, 1968, Gold joined Rudd in being one of the Columbia SDS activists who helped lead the 1968 Columbia Student Revolt, in which five Columbia University buildings were seized by over 700 anti-war Columbia and Barnard students. Following his suspension for his political activity during his senior year at Columbia in May 1968, Gold enrolled in a summer teachers training course. During the 1968-69 year, he worked as both a teacher in a private school and as a New York Regional SDS organizer of anti-war radical teachers for the newly formed Teachers for A Democratic Society (TDS) group. Death In 1969, Gold joined the Weatherman faction of Columbia SDS. Gold had become more militant after a visit to Cuba, during which he and some other U.S. anti-war activists met with representatives of the Vietnamese people who were also opposed to continued U.S. military intervention in Indochina.

Kathy Boudin and Cathy Wilkerson both survived the explosion. Gold was crushed to death by the building's façade, which killed him as he returned back to the townhouse. John Jacobs, the other member of the collective, was not present and went underground after the blast. This occurred, according to Susan Braudy's book Family Circle, after Gold "had just returned to the first floor parlor after his first brief trip to the Strand Book Store". Braudy's book also revealed that "in front of the burning house, an FBI agent who had been part of the surveillance team keeping watch on the young radicals quickly snapped pictures of the house's crumbling brick Greek-revival façade" and "since the buildings on the block were of significant design interest, [the FBI agent] had been posing as an architectural historian". After the 1970 bombing, many members of the Weathermen were on the
