He shares that fate with a certain Mr. Seimens and the famous Oscar 
Meyer Weiner.
That must be a German->American sound shift, some kind of extension to 
Grimm's law.

There also was a Mr. Hamming, but there never was a Mr. Hanning, at 
least not
in the business of weighting contents of time series.

That guy with the window function was one Mr. Julius von Hann, an
Austrian Meteorologist. It is therefore the Hann window.
