Skyscraperman is a 2010 memoir of Dan Goodwin, written by Dan Goodwin and co-written / edited by D. B. Guidinger. Dan Goodwin, an American rock climber known as SpiderDan, in the 1980s donned a Spider-Man suit and successfully scaled the outside of the tallest buildings in the world, including the Sears Tower, the John Hancock Center, and the North Tower of New York's World Trade Center. According to Goodwin, the reason he climbed tall buildings was to call attention to the inability of fire departments to conduct firefighting and rescue operations in the upper floors of skyscrapers.
