TITLE: Who is Mrs. Gerber?
QUESTION [22 upvotes]: This question on a theorem in information theory called Mrs. Gerber's lemma piqued my curiosity. Who is this individual, and why the "mrs." ?  A quick Google search was not informative, although it did produce a Mr. Gerber's lemma (arXiv:1802.05861) -- can someone enlighten me?

REPLY [28 votes]: Check out the original reference "A theorem on the entropy of certain binary sequences and applications - I" by Wyner and Ziv: http://doi.org/10.1109/TIT.1973.1055107. Footnote 2 on page one explains

This result is known as “Mrs. Gerber’s Lemma” in honor of a certain lady whose presence was keenly felt by the authors at the time this research was done.

I'm not sure you're going to get more of an explanation than that.
