Last name origin & meaning:
German and Jewish (Ashkenazic): from Middle High German
biber ‘beaver’, German Biber, or Yiddish biber, hence a nickname, possibly a
nickname for a hard worker, or from some other fancied resemblance to the
animal.
In some cases the surname may be habitational, from a house or some
other place named with this word. As a Jewish name it is largely ornamental.
