His books reflect this view of stained glass as an architectural art.
"The Lost Art". 1954.
"Stained Glass", an architectural art. 1965.
"The Language of Stained Glass", 1981.
"Rethinking the Forms of Visual Expression", 1990. This last book was as much about the relationship between art and architecture as with glass.
There is a final, posthumous volume, "Image of Light" which is a selection of his wonderful black and white photographs.
Between 1979 and 1982, when he ceased designing new glass commissions, he embarked on a series of black and white abstract paintings. These in turn led to a wonderful series of paintings done between 1984 and 1988 who's subject matter broadly falls into 2 categories. The industrial landscape series exploring the deserted industrial areas of lower manhattan and brooklyn between the bridges, and the green park series which are primarily set in central park and tanglewood in the berkshires. These paintings all explore the quality of light which is the prime link to his glass work. Some of these paintings are available for purchase.
