Jacques-Louis Soret
Encyclopedia
Jacques-Louis Soret was a Swiss
chemist
who in 1878, along with Marc Delafontaine
, first observed holmium
spectroscopically. Independently, Per Teodor Cleve
separated it chemically from thulium
and erbium
in 1879. 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.
The Soret peak
, a strong absorption band of hemoglobin
is also named after him.
His son was Charles Soret
, a recognized physicist and chemist in his own right.

Chemist
A chemist is a scientist trained in the study of chemistry. Chemists study the composition of matter and its properties such as density and acidity. Chemists carefully describe the properties they study in terms of quantities, with detail on the level of molecules and their component atoms...
