 Regardless of whether Hamblin independently invented the notation and its usage, he showed the merit, service, and advantage of the Reverse Polish way of writing programs for the processing on programmable computers and algorithms to make it happen.The second direct result of his work with the development of compilers was the concept of the push-pop stack (previously invented by Alan M. Turing for the ACE in 1945), which Hamblin developed independently of Friedrich Ludwig Bauer and Klaus Samelson.In the same year, 1957, Hamblin presented his stack concept at the first Australian Computer Conference.
