I. INTRODUCTION II. EARLY YEARS 2 Recently, one of Henry’s sons told me that Henry loved me. This is no great distinction as Henry thought positively of everyone. However, perhaps he loved some people more than others. He was a very warm and generous person. My parents were nervous when they were to meet such an eminent person. He immediately put them at ease. In any case, my truthful reply to his son was that I loved him. Henry treated me as an honorary son. The two scientists of whom I am most fond, Henry Eyring and John Barker, both treated me as a honorary family member. For this I am deeply grateful. Henry Eyring was grandson of Henry Eyring and Mary Brommeli, who came to America from Germany and Switzerland, respectively. His grandparents met as they travelled across the plains to Utah in 1860. They settled first in St. George in southern Utah and later were sent to northern Mexico to help establish a Mormon settlement. His grandfather was widely respected for his integrity. His grandmother spent some time in Berlin where she spent a brief period in jail because she refused to compromise her religious beliefs. His parents The author was pleased and honored to have a part in a symposium honoring Eyring that was part of an American Chemical Society Meeting in Salt Lake City in March, 2009. This article is based on the author’s talk in this symposium. A portion of this article together with two additional figures will appear in the Bulletin for the History of Chemistry , hereinafter referred to as the Bulletin article. Earlier reminiscences and biographies, including one by Henry Eyring, the scientist, and one by his grandson, Henry J. Eyring, have been published earlier 1 − $^{6}$. Jan Hayes, the organizer of the symposium and this issue, has pointed out to me that I am a coauthor of the last of Henry’s publications. This is somewhat accidental as my book with him was the second edition of Statistical Mechanics and Dynamics , the first edition appearing nearly twenty years earlier. Additionally, the publisher wanted camera ready copy for the second edition and since my employer at the time, IBM, could hardly be expected to have me devote all my time to the preparation of the manuscript for this book, the production of the camera ready copy took five years. Had the preparation proceeded more quickly, I would not have occupied this position.
