Who was the smartest man in the world?

With only a small amount of college, Langan has held a variety of labor-intensive jobs including construction worker, cowboy, firefighter, farmhand, and perhaps most famously, bar bouncer. Accordingly, he has sometimes been stereotyped as the sort of individual who combines an extremely high IQ with little or no official recognition in the academic "real world" of intellectual commerce . Langan currently owns and operates a horse ranch in northern Missouri.
