The Hard, Unleavened Cracker-Like Bread of the Jewish People

Thurber on 1933-vintage matzah:

During the past six months, something like five hundred and twenty million matzoth have been baked for Passover. A matzoh (unless we have it backward, that's the singular) is the hard, unleavened cracker-like bread of the Jewish people. Some of the matzoh bakers round about are interesting. The B. Manischewitz Company is the largest--in the world--with four plants, the nearest being Jersey City; that one takes care of New York business, a big proposition, for about half of the yearly output of the matzoh bakeries is consumed in this city.
