I've been photographing and studying photographs since I was an undergraduate in the late 1960's. I am retired from Georgetown University where I was associate dean of the Graduate School and taught courses in the history of photography. 

My favorite photographic subject is the urban landscape. 

My favorite quotation about photography was not written with photography in mind at all: "In its countless alveoli space contains compressed time.  That is what space is for."  From The Poetics of Space  by Gaston Bachelard
