PREFACE

This history of the Harvard College Observatory reviews the story from the mid-seventeenth century, when the first astronomical observations were made at Harvard; describes in detail the developments from the founding of the Observatory in 1839 through the first four administrations ; and ends with the death of the fourth director, Edward Pickering, in 1919. Of the several other accounts that have appeared in print, three deserve special mention. T h e earliest, which dealt with the period from about 1815, when the Harvard Corporation took its first official step toward the establishment of an Observatory, to the year 1855, was written by the first director, William Cranch Bond, and appeared in volume 1 of the Annals of the Harvard College Observatory. T h e next account, written by Professor Arthur Searle, covered the years 18551876 and appeared in volume 8 of the Annals. T h e third, written by Professor Solon I. Bailey and published in 1931 as Harvard College Observatory Monograph No. 4, recapitulated the events of the earlier periods and brought the narrative up to the year 1927. Unlike the previous histories, which were largely impersonal, the present volume proposes to give more than the bare statistics of physical growth, endowment, instrumentation, and research projects. By liberal quotation from correspondence, both personal and scientific in nature, we attempt also to portray something of the human qualities of the men and women who were closely involved with the Observatory. In addition to Observatory publications such as the Annals, the Annual Reports,

ν

Preface and the Circulars, we have drawn on hitherto unexplored primary material, the letters and documents relating to the Observatory that are preserved in the Archives of Harvard University. Although this book does not purport to be a history of American astronomy, preparing the work has entailed much supplementary reading to provide the necessary background. T h e sources used, other than the Archives, are cited in the notes to the individual chapters. T h e idea of preparing a new history was conceived by Professor Donald H. Menzel, the sixth director of the Observatory. T o make the book possible, he secured a grant from the National Science Foundation and, when that had expired, ensured the completion of the work by use of a gift from the late Richard Perkin of New Canaan, Connecticut. W e acknowledge a special debt to Dr. Menzel, who has generously and patiently advised, criticized, encouraged, and given invaluable help at every stage of the project, especially with reference to the scientific background. Our thanks go also to Mr. Douglas W. Bryant, University Librarian, for providing working facilities in the early months of this project; to Mr. Kimball C. Elkins of the Harvard University Archives, Mrs. Thomasine C. Brooks of the Phillips Library of the Observatory, and Miss Carolyn E. Jakeman of the Houghton Library for their aid in locating elusive material; to Miss Margaret Harwood and Mr. Leon Campbell for furnishing unpublished documents, rare photographs, and personal reminiscences; to Professor Owen J . Gingerich and Dr. Jesse L. Greenstein for reading parts of the manuscript and making helpful suggestions; to Mr. Roger Lowell Putnam, Mrs. Wayland S. Bailey, Dr. I. John Danziger, Miss Eleanor S. Upton, Mrs. Martha H. Liller, and Sr. Fernando L. de Romaña for supplying certain data and photographs; to Professor I. Bernard Cohen for obtaining the photograph of the Hancock telescope ; to Mrs. Catherine Coté and Mr. James K . Ufford of the Fogg Art Museum for help in assembling pictures from the Harvard University Portrait Collection, especially Figures 2, 3, 4, 8, 11, 12, 14, 15, 19, 21, 23, and 4 5 ; to Mr. Eugen E. Franck of the Observatory's photographic laboratory for securing usable prints of early astronomical photographs; and to Mrs. Abbie McLaughlin, Mrs. Linda McDermott, Miss Olga Choruzi, and Miss Joan Drees, who cheerfully typed a large part of the manuscript.

FOREWORD

Although Harvard College Observatory was not the first astronomical observatory in the United States, it has been the center of a large number of pioneer projects in astronomy. Many of the great figures in that science—European as well as American—have had more than casual contact with the Harvard Observatory. In the absence of a history of American astronomy, the story of scientific developments within one leading institution helps fill that gap. Harvard astronomers were among the first to recognize the potential of photography for astronomical research. T h e Harvard collection of more than half a million photographic plates provides a unique record of what has been happening in the sky over the past 90 years. Astronomers come to Harvard from all over the world just to consult this record, to see what this particular star or celestial object was doing in the distant past, changing brightness or drifting across the sky. Such studies have contributed materially to the understanding of such unusual objects as the recently discovered quasars. Space exploration, a field in which both the Harvard College Observatory and the Smithsonian Astrophysical Observatory have played major roles, has a link to the past as well as to the future. For, as orbiting astronomical telescopes reveal the existence of certain celestial objects with unusual or abnormal characteristics, records of the past will often provide important data for understanding or interpreting these mysteries. T h e history of past science is the paved road along which present-day science must travel into the future. I can only hope that this volume will inspire other historians to write a more detailed, full-scale history of American astronomy. I wish to thank personally the authors and the many other people and organizations that made this volume possible. DONALD H .

THE HARVARD COLLEGE OBSERVATORY

BEFORE THE OBSERVATORY 1642-1839

I Until the third decade of the last century it was still true that an American observatory was little more than a "tube with an eye at one end and a star at the other." 1 Astronomy at Harvard, however, did not wait upon the possession of tubes, much less upon an observatory building. As early as 1642 the "Laws, Liberties and Orders of Harvard College" listed astronomy as one of the subjects in the curriculum. Students heard lectures in their third (then senior) year; after Harvard added the fourth year in 1652, "Junior" and "Senior sophisters" studied from special texts, supplemented by disputations once a week on "phylosophical and astronomical questions." At what point Copernicus displaced Ptolemy in the curriculum is not exactly clear, but Samuel Eliot Morison concludes from his great study of the question that the "Copernican system was well established at Harvard before the 'New England Almanac for 1659' appeared." 2 These almanacs, prepared by tutors who were usually candidates for the ministry and chosen for the task by the President, were printed annually on a small press in the College Yard. That for 1659, produced by Zechariah Brigden, included an exposition of the Copernican system in an essay Morison regards as "the earliest extant . . . by a Harvard graduate," perhaps even the "first in popular science published in the English colonies" (Fig. 1). In another almanac following shortly on this example one author wrote gaily that the planets "dance 'illipticall Sallyes, Ebbs and flowes,' by reason of 'Magneticall Charmes' emanating from the Sun." (This description contains more truth than the writer could have known at the time, for although there is no connection with plane1
