    Description
    Sketch of a twin elliptic pendulum harmonograph invented by Joseph Goold. This drawing instrument used pendulums to generate patterns, typically Lissajous curves.

    Figure on the reverse of a printed description headed Sound-Curve Tracings by Joseph Goold, Stratford House, Nottingham. The three-page pamphlet was collected with an envelope containing three specimens of harmonograph outputs.

    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).
