Day 7 of our chemistry advent timeline looks at three scientists from the mid-1800s.
Germain Hess is familiar to chemistry students through Hess’s Law, which allows unknown reaction enthalpy changes to be calculated. There’s more on Hess’s Law here.
Norbert Rillieux was one of the first chemical engineers. He revolutionised sugar processing, allowing the production of better sugar at much lower cost. He also had to contend with racism when trying to patent his inventions, as this profile from the American Chemical Society describes.
Louis Pasteur is well known for his contributions to germ theory, but he also made some key contributions to chemistry. Chief amongst these was his discovery of molecular chirality and optical isomers.
