n.

“craftsman who makes wooden vessels,” attested from late 12c. as a surname, either from old english (unattested) or from a low german source akin to middle dutch cuper, east frisian kuper, from low german kupe (german kufe) “cask,” cognate with medieval latin cupa (see coop (n.)).

a dry cooper makes casks, etc., to hold dry goods, a wet cooper those to contain liquids, a white cooper pails, tubs, and the like for domestic or dairy use. [oed]

the surname cowper (pr-nounced “cooper”) preserves a 15c. spelling.
