Devices that produce curves by the rotation of circles (or gears) about one another constitute one class of harmonographs. In the simplest case, a point on one of the circles will trace a cycloidal curve. A number of devices of varying degrees of complexity and which make use of gears or pulleys in their operation have been invented over the years to draw various curves. This paper offers a survey of some of these.

Ibbetson wrote several books on “circular turning.” See National Union Catalog Pre-1965 Imprints (Mansell, Chicago, 1973), Vol. 263, p. 110.
I have not seen either reference. Proctor (Ref. 4, p. 194) refers to both of these in a long quote about the “geometric chuck” written by Henry Perigal, who had constructed a similar device by means of which several of the illustrations were made for Proctor’s book. L. W. Boord also drew several illustrations for this book using a device similar to Perigal’s.
Drach had referred to Perigal some years before. He wrote of curves shown in a demonstration “… by Mr. Perigal at Lord Northampton’s scientific soirée in March 1846. The Royal Society, Astronomical Society and Royal Institution, possess three volumes of various singular epicyclical curves executed by Mr. Perigal’s machinery, some of which are highly ornamental,… .”

(June, 1849
);the quotation appears on p. 448. De Morgan referred to diagrams of trochoidal curves that had been drawn by Perigal for the Penny Cyclopaedia; he also noted that Northampton (Spencer Joshua Alwyne Compton, second Marquis of Northampton) was president of the Royal Society from 1838 to 1849. Augustus De Morgan, A Budget of Paradoxes, edited by David Eugene Smith (Open Court, Chicago, 1915; Books for Libraries Press, Freeport, NY, 1969), Vol. 2, 2nd ed., pp. 19–20.
A brief obituary of Perigal may be found in “Obituary: Mr. Henry Perigal,” The Times (London), 9 June 1898, p. 6. In spite of these references to Perigal’s “machine” I have been unable to find further description of it.
Proctor also referred to Perigal’s invention of “… an ingenious instrument, called the kinescope (sold by Messrs. R. & J. Beck, of Cornhill), by which all forms of epicyclics can be ocularly illustrated. A bright bead is set revolving with great rapidity about a centre, itself revolving rapidly about a fixed centre,… and thus any epicyclic traced out.
The motions are so rapid that, owing to the persistence of luminous images on the retina, the whole curve is visible as if formed of bright wire.” Reference 4, pp. 194–195.
This description is virtually identical to an apparatus attributed to Charles Wheatstone and described (and illustrated) by Ganot who called it “Wheatstone’s photometer.” Elementary Treatise on Physics, Experimental and Applied, translated and edited from Ganot’s Éléments de Physique by E. Atkinson (William Wood, New York, 1899), 15th ed., p. 516.
Its description is sufficiently different from the one described by Wheatstone on 8 March 1833 before the Royal Institution, which also made use of luminous points carried by a wheel moved by a train of gears. See The Athenæum, 170–171 (16 March 1833).
Wade noted that this 1833 experiment had not seemed to have been published, nor does he mention the “photometer.” Nicholas J. Wade, Brewster and Wheatstone on Vision (Academic, London and New York, 1983), p. 313.
Frick described the “reflection photometer” (Reflexphotometer), a nearly identical apparatus, which he attributed to Wollaston.
See Joseph Frick, Dr. J. Fricks Physikalische Technik;…, Zweiter Band, Zweite Abteilung (Friedrich Bieweg und Sohn, Braunschweig, 1909), 7th ed., p. 1759. I have been unable to find original references to either of these devices.
Wheatstone’s interest in acoustical phenomenon also led to his construction of machines to demonstrate wave motion. A discussion of this appears in Howard A. L. Dawes, “Wheatstone’s wave machine: A physical model of light,” in Making Instruments Count: Essays on Historical Scientific Instruments presented to Gerard L’Estrange Turner, edited by R. G. W. Anderson, J. A. Bennett, and W. F. Ryan (Variorum, Aldershot, Hampshire, UK and Brookfield, VT, 1993), pp. 127–138.

Machines designed to demonstrate wave motion are related to, but not the same as, harmonographs. I have made no attempt to survey the literature of this extensive class of apparatus. However, Barus gives a detailed discussion of a complex apparatus of his design in

Thomas B. Greenslade, Jr. has kindly provided the following biographical note on Pickering:
—A prominent example [of an important figure in 19th century American science] is Edward Charles Pickering (1846–1919), who spent the last forty two years of his life as the Director of the Harvard Observatory. He prepared for college at the Boston Latin School, and was awarded his S. B. degree from Harvard’s Lawrence Scientific School at the age of nineteen. After a year of teaching mathematics at Lawrence Scientific School, he crossed the Charles River in 1866 to join the faculty of the new Massachusetts Institute of Technology, which at that time was on the south side of the river in Boston. For one year he was an assistant instructor of mathematics, and from 1868 to 1877 he was the Thayer professor of physics at M.I.T.

Donkin

It is now constructed by Messrs. Tisley and Spiller.” John Tyndall, Sound (Appleton, New York and London, 1903), 3rd ed., p. 422. Further discussion may be found in W. F. Donkin, Acoustics (Clarendon, Oxford, 1884), 2nd ed., pp. 50–56.

E. W.
Blake
, “A machine for drawing compound harmonic curves
,” Am. J. Otology
1
, 81
–86
(plus plates) (April, 1879
).Blake noted that Donkin’s apparatus could draw the combination of only two curves; his could draw the combination of three. A biography of W[illiam] F[ishburn] Donkin, who was Savilian professor of astronomy at Oxford, may be found in William Jerome Harrison, “Donkin, William Fishburn,” Dictionary of National Biography (Oxford U.P., London), Vol. V, p. 1125.

Rigge’s account of the campylograph is based on his correspondence with Dechevrens. He noted that he had not had access to the articles cited above, even though he had heard of them. Dechevrens was known principally as a meteorologist and as an authority on the theory of cyclones, for which he is still cited. See: Gisela Kutzbach, The Thermal Theory of Cyclones: A History of Meteorological Thought in the Nineteenth Century (American Meteorological Society, Boston, 1979), pp. 137–138;
the National Union Catalog Pre-1965 Imprints (Mansell, Chicago, 1973), Vol. 136, p. 247 provides a suggestive list of his work. He was born 26 July 1845 and died 6 December 1923; he had worked at the St. Louis Observatory in Jersey, Channel Islands from 1887 until his death.

All references here are to the first design, which has greater versatility for the purposes described. A later version came with a curved triangular wheel for tracing different curves. General Mills Fun Group, Inc., Cincinnati, OH, copyright, 1972.
This wheel is known as a “Reuleaux triangle.” Its properties have recently been described in

The earlier versions came with pins to fasten the wheels to cardboard, which, in the wisdom of hindsight, are not now considered appropriate for young children to use. The later versions do not use pins.The term, “Spirograph,” was introduced in an entirely different context in 1890. It was: “An instrument which provides a continuous tracing of the movements of the lungs during respiration.” The Oxford English Dictionary (Clarendon, Oxford, 1989), Vol. XVI, 2nd ed., p. 262.

For most of his professional life he contributed extensively to professional and popular journals, writing on astronomy, physics, mathematics, and the history of astronomy. This writer is currently compiling a bibliography of his writings and intends to write a more detailed account of his machine, based on actual examination of it.

While dated, Ronald Pearsall, Collecting and Restoring Scientific Instruments (Arco, New York, 1974) is useful. The author provides an extensive glossary of the names of different instruments; strangely, no form of harmonograph is among them.
This should be supplemented by Gerard L’E. Turner, Antique Scientific Instruments (Blandford, Poole, Dorset, UK, 1980);
Nineteenth-Century Scientific Instruments (Southby Publications, University of California Press, Berkeley, 1983). Both are illustrated with a number of colored plates of apparatus.

As noted above, Lawrence and Lockwood make the distinction. Sharp, in his useful discussion of these curves encountered in the gears of a bicycle, makes the same distinction.
