    Description
    Lissajous curve made by a twin elliptic pendulum harmonograph, a mechanical device invented by Joseph Goold.

    Figure accompanying a printed description headed Sound-Curve Tracings by Joseph Goold, Stratford House, Nottingham. This three-page pamphlet was collected with an envelope containing three specimens of harmonograph outputs, of which this is one.

    Joseph Goold was not a Fellow of the Royal Society. He contributed to the book Harmonic vibration and vibration figures by Joseph Goold, Charles E Benham, Richard Kerr and L R Wilberforce (1909) and was noticed in Annie Besant’s Thought-forms (1901).
