Michael Gary Turnbull (born April 13, 1949) is a Canadian-born American architect who has spent much of his career in the public sector as a custodian of major public buildings, notably the U.S. Capitol in Washington, D.C., as the assistant to the Architect of the Capitol[1] and as the Director of Design and Construction at the Art Institute of Chicago.
In recognition of his achievements in architecture and his dedication in maintaining these national treasures, the American Institute of Architects elected him to its College of Fellows in 2005.
While a resident of the Chicago Metropolitan Area, Turnbull served as a member of the board of governors of the Illinois St. Andrew Society.
The Supreme Court project was the most comprehensive Turnbull was responsible for, working closely with Justices Sandra Day O'Connor, Anthony Kennedy, and David Souter.
For his service to the Supreme Court of the United States, both Justices O'Connor and Kennedy recommended Turnbull for his Fellowship in the American Institute of Architects.
