A leading geochemist who became well known for creating the first high-precision mass spectrometer, called Lunatic I, that measured isotope ratios in lunar samples from the Apollo missions.

A view of a bridge, with the New Orleans skyline visible in the distance between the bridge and the water. A purple tint, a teal curved line representing a river, and the text “#AGU25 coverage from Eos” overlie the photo.
