Named in honor of engineer H. Ralph Uhlherr, a founder of the Siemens plant in Melbourne. An indefatigable collector of tektites, Uhlherr has meticulously recorded and mapped over a thousand australites from the Port Campbell Embayment of Victoria, thereby helping to resolve the conflict between the apparent young stratigraphic age of the tektites and the middle Pleistocene ages obtained by various chronometric methods.
