Gerlach Fiedler (1924-2010) dubbed Cookie Monster (Krümelmonster) into German for Sesamstrasse, from 1973 to 1974.

Fiedler was replaced by actor Alexander Welbat, then Edgar Ott took over the role. Following Ott's death in 1994, Welbat's son Douglas Welbat took over the character, and still performs the voice today.
