Constructing this virtual time-traveling walking tour started with reading Billy Harris’s reviews. Some of those reviews contained special surprises for Marymount Manhattan readers. The man on the left in the photo above is -time MMC adjunct professor Dan Diggles. Harris’ reviews always noted the where the performances took place, so that one may still visit the places today. The reviews’ descriptions of scripts, actors, and sets led back to Harris’ research files, and to more information about the performances and their settings. The addresses also led to New York City’s Building Information System and its Department of Finance. Both of these sites maintain data that allow one to see the change in the condition and the value of the building over time. Thus one can study the neighborhood along with the performance.
