6° OF SEPARATION, ARCHITECTURE STYLE: MARTY MCFLY → CHRISTOPHER WREN

In celebration of Back to the Future Day—October 21, 2015—and the 378th birthday of the great English architect Christopher Wren—October 20th, 1632—a six-step link between the two:

1. In Back to the Future, Doc lives in the famous Gamble house by architects Greene & Greene

2. Henry Greene apprenticed at Shepley, Rutan + Coolidge

3. Shepley, Rutan and Coolidge all worked for Henry Hobson Richardson, the first of America's so-called "trinity" of great architects, who bequeathed his firm to the three while on his deathbed.

4. Richardson designed the famous Trinity Church in Boston

5. The windows in Richardson's Trinity Church were done by renowned designer William Morris

6. William Morris also decorated the state apartments at St. James Place, which were designed by Christopher Wren.  

If Wren were alive today, he'd be 383 years young.  His most famous work, St. Paul's Cathedral in London,  is only slightly less old at 342.  Here's to hoping that big dome graces London's skyline for another 342....at which point it may look something like this
