Actually his "discoveries" didn't just claim that pi was 3.2, it claimed (sometimes implicitly) several values. The wikipedia article is more informative:
Google finds many more references of varying detail.
Most people know the approximation 22/7, and many people actually think this is the exact value. A much better approximation is 355/113, unreasonably good, as evidenced by the unusually large integer in the continued fraction expansion of pi.
