Frederic M. Richards
Biochemist, biophysicist, crystallographer, and sailor; founder and chair of Department of Molecular Biophysics and Biochemistry at Yale University (1925-2009)

Frederic Middlebrook Richards (August 19, 1925 – January 11, 2009), commonly referred to as Fred Richards, was an American biochemist and biophysicist known for solving the pioneering crystal structure of the ribonuclease S enzyme in 1967 and for defining the concept of solvent-accessible surface. He contributed many key experimental and theoretical results and developed new methods, garnering over 20,000 journal citations in several quite distinct research areas. In addition to the protein crystallography and biochemistry of ribonuclease S, these included solvent accessibility and internal packing of proteins, the first side-chain rotamer library, high-pressure crystallography, new types of chemical tags such as biotin/avidin, the nuclear magnetic resonance (NMR) chemical shift index, and structural and biophysical characterization of the effects of mutations.
Richards spent his entire academic research career at Yale University, where he became Sterling Professor of Molecular Biophysics and Biochemistry in the department that he created and chaired, "one of the major centers in the world for the study of biophysics and structural biology". He was elected to the National Academy of Sciences USA and the American Academy of Arts and Sciences, and received many other scientific awards. He served as head of the Jane Coffin Childs Memorial Fund for Medical Research and was elected as president both of the American Society for Biochemistry and Molecular Biology (ASBMB) and of the Biophysical Society.
Personal biography
Richards was born on August 19, 1925, in New York City to George H. Richards and Marianna Middlebrook Richards. Both parents were from old New England families who had settled in Fairfield and New London, Connecticut, in the 1600s. The family usually spent summers in Connecticut, giving Richards an early affinity for the area which continued through his career at Yale University. He had two older sisters, Marianna and Sarah.
The public source identifies “Frederic M.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Frederic M. Richards”, the useful work is to connect “biochemist, biophysicist, crystallographer, and sailor; founder and chair of Department of Molecular Biophysics and Biochemistry at Yale University (1925-2009)” to the records capable of establishing context and consequence.
The record creator and administrative purpose are central evidence, because official documentation reflects both action and institutional priorities. The source revision retrieved here is dated Sep 21, 2026. The linked authority identifier is Q5497091. VIAF identifies the subject as 57911813. The Library of Congress control number is n80060301. 1 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1925, 2009 and 1967.
Later summaries often reconcile disputed chronology or motive more neatly than the contemporary record permits. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
