I never met a genius until i went to college at MIT in the late 1970s. I met a bunch of them in college and i have felt since then that genius and insanity sit right next to each other in the mind.
I was reminded of that the other night when i went to see a movie called My Architect.
My wife Joanne, the Gotham Gal, has a good review of the film on her blog.
Lou Kahn was a genius, but he was also a lunatic. If you are interested in archicture or genius of any kind, i think you'll find this movie fascinating.
