During my early years at Minnesota I conducted an evening enzyme seminar.

A painstaking course in qualitative and quantitative analysis by John Wing gave me an appreciation of the need for, and beauty of, accurate measurement.

Family trips to Yellowstone and to what are now national parks in Southern Utah, driving the primitive roads and cars of that day, were real adventures.

Mountain hikes instilled in me a life-long urge to get to the top of any inviting summit or peak.

The geographical isolation and lack of television made world happenings and problems seem remote.
