<biogHist>
<abstract>C. L. Hamblin's proposed computer in about 1960 led to the idea of the 'recursive stack', based on the Reverse Polish notation of Lukasiewicz (1920) and first implemented on the UTECOM as the GEORGE programming system. This was taken up by the English Electric Company in its multi-programmed KDF9 system, which was given two hardware register stacks.</abstract>
