One can only imagine just what Sutton could have achieved if he was less isolated, more protective of his innovations and patents, more entrepreneurial, or had the right financial backing such as that which Tesla secured with the entrepreneur George Westinghouse. Lorayne Branch’s advocacy is compelling; Henry Sutton is an unsung Australian inventor arguably on a par with Edison, Bell, Tesla and Marconi. Her extensively researched monograph goes a long way in delineating his achievements and placing them in a broader context. This is a book that would certainly inspire any young Australian inventor and it deserves a large audience.
