Morgan Stanley had offices located on 24 floors across buildings 2 and 5 of the World Trade Center in New York City. These offices had been inherited from Dean Witter which had occupied the space since the mid-1980s. The firm lost 13 employees during the September 11 attacks in 2001 (Thomas F. Swift, Wesley Mercer, Jennifer de Jesus, Joseph DiPilato, Nolbert Salomon, Godwin Forde, Steve R. Strauss, Lindsay C. Herkness, Albert Joseph, Jorge Velazquez, Titus Davidson, Charles Laurencin and Security Director Rick Rescorla) in the towers, while 2,687 were successfully evacuated by Rick Rescorla. The surviving employees moved to temporary headquarters in the vicinity. In 2005 Morgan Stanley moved 2,300 of its employees back to lower Manhattan, at that time the largest such move.
