The phenomenon may have first been documented at Pomona College in 1964, when Professor Donald Bentley proved that all numbers are equal to 47. Coincidentally, 47 seems to occur on or near the college campus with amazing frquency, even by enthusiast standards.

But make no mistake: 47 is everywhere and people were noticing it long before 1964. The 47 Society Web Site is the global source for 47 information.
