This person was a physical chemist whose research encompassed decomposition and combustion of hydrocarbons, electrochemistry, and free radical research.

This person was initially recognized for their work on electrochemistry and thermodynamics, which involved investigating the reaction of an alkali metal with a halogen to form an ionic compound, resulting in a method to calculate lattice energies. Another important area of this person’s research led to the development of a high pressure catalytic gas reaction that greatly impacted the manufacture of fertilizers and explosives.
