Chris Raetz, scientist and enduring friend

When Chris Raetz died of cancer on August 16, 2011, the scientific world lost a polymath, and we lost a cherished friend. Chris was born in East Berlin in 1946. At age 5, his family emigrated to Ohio, where his parents worked for Olin Chemicals. Chris attended Hopkins School in New Haven, Connecticut, and then Yale University, where he majored in chemistry. Bill Wickner, a fellow chemistry major, recalls leaving campus early one weekend, relying on Chris to take notes in their Friday chemistry course. Chris's notes were elegant and clear, except for the derivation of the Grabowski equation. Chris admitted he had not quite understood it, and therefore Bill asked the professor to explain it again in Monday's class. The professor looked puzzled and then, amused, realizing how thoroughly Chris had bamboozled Bill about an imaginary equation. A lifelong friendship was born.
