IMMACULATE CONCEPTION CATHEDRAL, BURLINGTON, VT 1977

When Robert Sowers could not complete the 10 half round windows, after installing the Great Cross window, David Wilson was interviewed and received the commission. These 10 windows, 5 on each side, have been referred to as the "Protractor Series". A subsequent recommendation from Edward L Barnes led to the first project, The Jupiter Island house, with Kevin Roche John Dinkeloo & Associates.
