14. According to James Glaisher, who doesn't mention Schilt, the main calculating machines shown at the exhibition were those of Staffel (which could compute square roots) and Thomas. It is easy to guess that Schilt's machine received little attention. J. Glaisher, "On Philosophical instruments and processes, as represented in the great Exhibition," Lectures on the results of the Great Exhibition of 1851 delivered before the Society of Arts, Manufactures, and Commerce, at the suggestion of H.R.H.

15. Schilt was born in Grenchen, near Solothurn in Switzerland, and went to work in Strasbourg in Schwilgué's workshop, where he was mainly busy working on tower clocks. When he returned to Switzerland, he built many tower clocks around Solothurn. (Information on Schilt from P. Kidwell, Smithsonian Institution.)
