The Lemniscate of Gerono is a special case of the Lissajous curves. The dates for the two mathematicians are fairly close: Gerono (1799-1891) and Lissajous (1822-1880). Historically who has priority for the lemniscate? Was Lissajous aware of Gerono's work when he introduced his curves?

  • $\begingroup$ According to French wikipedia "Gerono's lemniscate is a plane curve studied by Grégoire de Saint-Vincent in 1647, next by Gabriel Cramer en 1750". Perhaps the question is when or why did it get this name. Lissajous' work is online (35p.), no mention. $\endgroup$ – sand1 Jun 15 '18 at 15:14
  • $\begingroup$ Gerono may not have been aware of these eariler sources. My question concerns the (possible) relation between Gerono and Lissajous as far as these curves are concerned. $\endgroup$ – Mikhail Katz Jun 17 '18 at 7:59
