scholars who continued to distinguish themselves in later years: James Baker, renowned astronomer and optical designer; John Bardeen, twice Nobel prize winner in physics (transistors and theory of superconductivity); James Fisk, president of Bell Telephone Laboratories; Henry Guerlac, historian of science; Paul Samuelson, Nobel prize winner in economics; Stanislaw Ulam, mathematician and coinventor of the hydrogen bomb; Robert Woodward, chemist and Nobel prize winner (synthesis of quinine); Willard Van Quine, mathematical logician; Fred Skinner, psychologist; Garrett Birkhoff, mathematician; E. Bright Wilson, chemist; and others.⁵ Dave Griggs's scientific contributions to geophysics during his tenure as a junior fellow are described in the next section-but here a few words about Dave as a person.

A single junior fellow was assigned to one of the houses where he lived with resident students and dined with distinguished faculty members who were also assigned to houses as tutors. Thus, Dave Griggs and one of the authors (I.A.G.) were assigned to Leverett House. There were four suites on each floor, and Dave and I found ourselves neighbors. While Dave's principal experimental research work was done at the Jefferson Physical Laboratory (his laboratory was flanked by Professor Bridgman's laboratory on one side and my laboratory on the other), his living room at Leverett House was always crammed with experiments: long-term deformation (creep) of rocks under applied loads, mountain-building models, and related experiments. Every opportunity that offered itself for mountain climbing (or skiing for that matter) was seized. Another resident on "our floor" was Agnew Bahnson, a well-to-do (by our standards) student who owned a Buick roadster. In the summer of 1936, Agnew and Dave set out to go mountain climbing in the Caucasus Mountains, a mountain chain linking the Caspian Sea and the Black Sea—a new range to climb and
