We take our hats off to the brilliance and playful spirit of the late IAIN ROBERTSON (1948–2021) who was a former chair of the University of Washington’s Landscape Architecture Department and an admired, internationally known academic and landscape architect. A native of Edinburgh, Scotland, Professor Robertson focused on the role of creativity in the practice of design. He was revered for his ability to inspire students, colleagues, and professionals to push beyond their preconceived boundaries to imagine the unimaginable.
