Got me going as well....Apparently from all the information we have over here, we only have his
first innitial "S". It is possible that for some reason, he did not want
his first name published. Someone that I work with, told me that he heard
that his first name may be "Sam". but don't quote this to be accurate. I
am
still digging in to this, because I am now curious.

Butterworth crossover A type of crossover circuit utilizing low-pass filter
design characterized by having a maximally flat magnitude response, i.e., no
amplitude ripple in the passband. This circuit is based upon Butterworth
functions (or Butterworth polynomials). [For the mathematically inclined,
these polynomials represent a specialized solution to a general MacLaurin
series based upon a Taylor series expansion. Named after S. Butterworth, a
British engineer who first described this response in his paper "On the
Theory of Filter Amplifiers," Wireless Engineer, vol. 7, 1930, pp. 536-541.
Eleven years later, V.D. Landon coined the phrase maximally flat in his
paper "Cascade Amplifiers with Maximal Flatness," RCA Review, vol. 5, 1941,
pp. 347-362.]

Does anyone happen to know the first name of the inventor of the
Butterworth filter? Or anything else about him? Or whether
Butterworth actually invented it? I can't find anything online...
You are missing the key ingrediant: It is his wife, known only as Mrs."Butterworth" is a type of polynomial resulting in a transfer function which
is implemented by a Low Pass, High Pass, Band Pass or Band Reject passive
or active circuit. The roots of this polynomial fall on a unit circle.

Google says not....You are missing the key ingrediant: It is his wife, known only as Mrs.
Butterworth, who is the more famous family member. She was an employee of
a
large, multi-national food conglomerant in the 1930s. While working as a
nutritionist, she invented a way to manufacture pancake syrup from cow
mesenteries, and offered her likeness as a sales gimmick for the
commercial
produce. It is still offered for sale in the USA. Obviously, her
contributions to the general health and welfare far outweighed those of
her
husband, and she is, therefore, much more widely known.
Or...maybe not.
Oh.Or...maybe not.
Google says not....

The award of an OBE made me look at the London Gazette at
http://www.gazettes-online.co.uk/archiveSearch.asp?WebType=0&Referer=WW2
where I found the following in the Birthday Honours for 1942:
