A pioneer of professional lighting design, Richard Kelly (1919-1977), laid the philosophical foundations for 'perception-orientated' architectural lighting in the 1950's, defining three varieties of light: ambient luminescence, focal glow and play of brilliants. His theories were put into practice in a series of spectacular projects such as at the Seagram Building in New York, designed by Ludwig Mies van der Rohe and Philip Johnson.

ERCO and ELDA+ proudly presents this touring exhibition which, drawing on the Richard Kelly archive, explores both the philosophy and the practice of this famous American lighting designer and architect and his visionary approach to architectural lighting, daylight usage and luminaire design.
