At 12:40 am on 1 December 1928, a man aged in his 20s was found lying unconscious on a street in Perth. He had severe injuries to his head and was taken to Perth Hospital for treatment. Several days later a trepanning operation was performed and, while it was successful, it may have caused him to develop encephalitis. When the man eventually regained consciousness, he had lost all knowledge of his identity.
The operation, however, though it restored Brown to life, robbed him of some portion of his mental faculties and, from that day, he has been unable to remember any incident which took place before the operation. His life, up to that date, has been a blank to him ever since.
At the time of his admittance to hospital his address was recorded as the Horseshoe Coffee Palace in Perth. Also provided was the name of a friend who lived in Subiaco. Despite police efforts to locate the person, no one by that name was found. The man had no other relatives or friends and he remained in hospital, unidentified, for nearly a year. He was eventually dubbed, William Brown.
