Otto Grande was a Czechoslovakian-born hotel steward at Perth, Australia who was charged and convicted in June 1956 for an assault that he claimed to have done while in a fugue state. While at trial, Grande was described in press accounts as a refugee and inventor who had drafted a perpetual motion design but had not built a model at that time.

'I am satisfied my invention is an accomplished fact,' he said. 'I never made any model but drew up plans and designs. I discussed my invention with a number of people, but they all laughed at me and said it was impossible.'"
