In 1912, when he died in Heidelberg, Germany, D.H. Burnham and Co. was the world's largest architectural firm. Even legendary architect Frank Lloyd Wright, although strongly critical of Burnham's Beaux Arts European influences still admired him as a man, eulogized: "(Burnham) made masterful use of the methods and men of his time... (as) an enthusiastic promoter of great construction enterprises... his powerful personality was supreme." The successor firm to Burnham's practice was Graham, Anderson, Probst & White, which continued in some form until 2006.
