Wild at Zimmerwald. Totziens, the Dutch word for "goodbye", accompanies the discoverer's best wishes for the future of research on minor planets in general and the fate of this body in particular. Likely to be chronologically the last of his discoveries, it was found shortly after the IAU General Assembly in the Dutch capital.
