Edwin Armstrong, the man who invented FM Radio, had a penchant for climbing radio towers. Sometimes he would climb to the top and hang from his heels when he got to the apex.
Armstrong once climbed RCA’s 115-foot north tower on the roof of the 21-story Aeolian Hall located in Manhattan. After sending a copy to David Sarnoff, the head of RCA, Sarnoff had him banned from the RCA building.
Oddly, Armstrong also sent a duplicate copy to Sarnoff’s secretary, Marion MacInnis, and she wound up marrying him.
