Bessemer's assertion that he had approached "within measurable distance" of anticipating the Siemens-Martin process, made in a paper presented at a meeting of the American Society of Mechanical Engineers (Transactions of the American Society of Mechanical Engineers, 1897, vol. 28, p. 459), evoked strong criticism of Bessemer's lack of generosity (ibid., p. 482). One commentator, friendly to Bessemer, put it that "Bessemer's relation to the open-hearth process was very much like Kelly's to the Bessemer process.... Although he was measurably near to the open-hearth process, he did not follow it up and make it a commercial success...." (ibid., p. 491)
