Born in Pittsburgh in 1951, William B. (“Billy”) Harris settled in New York City upon graduation from Trinity College in Hartford, Connecticut, in 1969. A freelance performing-arts critic, he reviewed performances for numerous area newspapers collecting a file of clippings, programs, advertisements and correspondence as he did so. Upon his death in 2000, his family donated his research files to Marymount Manhattan College. Friends added to the initial deposit. The files allow us to take a time-traveling walking tour through Lower Manhattan, to join Billy Harris at memorable theatre and to watch as the increasing traffic visiting downtown for cultural events sets the stage for the revival of the area as a residential, cultural, and shopping district.
