horace greeley robinson also known as hyman rabinowitz conducted a lecture and exhibition of wireless telegraphy at glen's concert hall, collins st., melbourne in august and september 1906. in his stated role as marconi representative in australia was providing, upon request, demonstrations of marconi wireless telegraphy equipment at the premises of the company munroe and munroe, 318 collins st., melbourne during august and september 1906. similar lectures and demonstrations were also offered at centenary hall, york st., sydney. but in an interesting twist, it emerged that the demonstrations had been made to lure investors into purchase of shares in the marconi company. large sums were paid but few investors ever saw their shares. robinson / rabinowitz was arrested in new york and charged with larceny under false pretences in relation the shares. while it was little publicised at the time, robinson / rabinowitz was the recipient of the first experimental licence issued by the department and was no doubt utilised by him to give an air of legitimacy to his scam.
