User: Who was Alexander Greek Thomson
Assistant: Alexander Greek Thomson (9 April 1817 – 22 March 1875) was an eminent Scottish architect and architectural theorist who was a pioneer in sustainable building. Although his work was published in the architectural press of his day, it was little appreciated outside Glasgow during his lifetime. It has only been since the 1950s and 1960s that his critical reputation has revived—not least of all in connection with his probable influence on Frank Lloyd Wright.

Henry-Russell Hitchcock wrote of Thomson in 1966: "Glasgow in the last 150 years has had two of the greatest architects of the Western world. C. R. Mackintosh was not highly productive but his influence in central Europe was comparable to such American architects as Louis Sullivan and Frank Lloyd Wright. An even greater and happily more productive architect, though one whose influence can only occasionally be traced in America in Milwaukee and in New York City and not at all as far as I know in Europe, was Alexander Thomson".
