London, United KingdomLive Auction
Description: utilising 3 pendulums to create a complex geometric pattern similar to Lissajous curves, presumably by the pendules drawing light patterns onto photographic or otherwise treated paper, mounted onto board, with gift inscription on the verso dated 1956, 290 x 390 mm., a little minor wear and lifting at edges, some loss to paper backing mount, [c.1956]. Extremely similar to the 'rhythmograms' created by architectural photographer Heinrich Heidersberger (1906-2006), which innovatively utilised harmonically muffled pendulums to create traces of light on photographic material via a mechanically linked mirror and a point source of light. The inscription on the back suggests that this work was exhibited in Darmstadt in 1955/56, and mentions the pendulum system, but it is unclear whether the inscription (signed seemingly "Lewis") is from the artist or the exhibition organiser Considering Heidersberger only pioneered this form of artwork in 1955, perfecting it over subsequent years, it seems unlikely it could've been undertaken by another artist so quickly, but there is nothing to prove it is by Heidersberger.
