Jacques-Louis Soret (30 June 1827 – 13 May 1890) was a Swiss chemist who in 1878, along with Marc Delafontaine, first observed holmium spectroscopically.[1][2] Independently, Per Teodor Cleve separated it chemically from thulium and erbium in 1879.[3][4] The three are given credit for the element's discovery.

Soret was also responsible for correctly working out the chemical composition of ozone as being three oxygen atoms bound together.[5][6][7]

The Soret peak, a strong absorption band of hemoglobin is also named after him.[8]

His son was Charles Soret, a recognized physicist and chemist in his own right.
