Michael Devonshire, Principal and Director of Conservation, Jan Hird Pokorny Associates (JHPA), will describe the history of windows, the social and artistic perception of windows, and examine how windows have functioned in history.
Mr. Devonshire will review the historic, stylistic and technological changes to the window as an architectural element, as it evolved from rudimentary hand-made components to machine-made. He will detail how windows are essential and character-defining components of historic buildings.
