(1911–97). English architectural and garden and architectural historian. A prolific writer and distinguished scholar, he made a major contribution over many years to several aspects of garden and architectural history, but his greatest achievement by far was his magisterial English Mediaeval Architects: A Biographical Dictionary down to 1550, first published in 1954, and subsequently revised. Based on documentary sources, it illumines the English medieval architectural world with gracefully presented facts.
