9. Around 1950, Alonzo Church discovered in Marquand’s papers at Princeton a fairly elaborate circuit diagram for a logic machine, thus establishing that Peirce’s recommendation had been acted on. It is not known whether an electrical logic machine was built. Ken Ketner has argued that Peirce himself drew the wiring diagram, probably in 1887. See Ketner’s article, with Arthur F. Stewart: “The Early History of Computer Design: Charles Sanders Peirce and Marquands Logical Machines,” The Princeton University Library Chronicle, Vol. 45, 1984, pp. 187–211. Alice and Arthur Burks discuss the Marquand diagram in Appendix A of The First Electronic Computer: The Atanasojf Story (University of Michigan Press, 1989), pp. 339–48, and conclude that it marks a significant advance in computing engineering theory—or would have had it become known. Although they do not believe that Peirce drew the elaborate circuit diagram, they do argue that it is plausible to credit Peirce with being the first to have conceived of an electrical general-purpose programmable computer, but they find no clear evidence that Peirce’s or Marquand’s ideas had any influence in the development of electronic computing.

24. The article in Journal fur die reine und angewandte Mathematik—referred to by Peirce as Crelle’s Journal—has not been identified. It is clear, from Risteen’s 4 Aug. 1887 letter, that Peirce had recommended a “demonstration,” probably in an 1887 issue, in connection with the study of curves.

44. In his definition of “gravity” for the Century Dictionary, Peirce wrote: “The words gravity and gravitation have been more or less confounded; but the most careful writers use gravitation for the attracting force, and gravity for the terrestrial phenomenon of weight or downward acceleration which has for its two components the gravitation and the centrifugal force.”
