Publications of the United States National Museum

The scholarly publications of the United States National Museum include two series, Proceedings of the United States National Museum and United States National Museum Bulletin.

In these series are published original articles and monographs dealing with the collections and work of the Museum and setting forth newly acquired facts in the fields of anthropology, biology, geology, history, and technology. Copies of each publication are distributed to libraries and scientific organizations and to specialists and others interested in the various subjects.

The Proceedings, begun in 1878, are intended for the publication, in separate form, of shorter papers. These are gathered in volumes, octavo in size, with the publication date of each paper recorded in the table of contents of the volume.

In the Bulletin series, the first of which was issued in 1875, appear longer, separate publications consisting of monographs (occasionally in several parts) and volumes in which are collected works on related subjects. Bulletins are either octavo or quarto in size, depending on the needs of the presentation. Since 1902 papers relating to the botanical collections of the Museum have been published in the Bulletin series under the heading Contributions from the United States National Herbarium.

Acknowledgments

The writer wishes to acknowledge his great indebtedness to the various compilations relating to clockmakers and instruments which have been consulted in the preparation of this work, and which have provided an invaluable basis for it.

He is especially grateful for the generous and interested assistance of the many who have cooperated in making this work possible. Particular credit must be given to Mrs. H. Ropes Cabot of the Bostonian Society; Mrs. Mary W. Phillips of the Department of Science and Technology of the U.S. National Museum; Prof. Derek J. de Solla Price, Avalon Professor of the History of Science at Yale University; Mr. Stephen T. Riley, Director of the Massachusetts Historical Society; and Mr. Charles E. Smart of Troy, New York.

Preface

Within recent years fairly exhaustive studies have been made on many aspects of American science and technology. For example, there have been numerous works relating to clocks and clockmakers, so that the collector and horological student have a number of useful sources on which to rely. More recently there has been a series of publications on the development of American tools and their makers. Until now, however, no systematic study has been attempted of the scientific instruments used in the United States from its colonial beginnings. While several useful regional lists of instrument makers in early America have been compiled from advertisements in contemporary newspapers and published as short articles, these, however, are fragmentary, and are inadequate to the need for documentation in this field.

With the rapidly growing interest in the history of science, it becomes necessary to have a more complete background for the student and the historian alike. It is desirable to have a more comprehensive picture of the work of the scientific practitioners of the earlier periods of American scientific development, and of their tools. At the same time it is essential to have a history of the development and distribution and use of scientific instruments by others than the practitioners and teachers. The role of the instrument maker in the American Colonies was an important one--as it was in each epoch of the history of science in Europe--and it deserves to be reported.

To make a comprehensive study of American scientific instruments and instrument makers in the American Colonies is no simple matter, partly because of an indifference to the subject in the past, and partly because of the great volume of sources that must be sifted to accomplish it. Such a project would require an organized search of all published reference works relating to the field and associated topics, of all contemporary newspapers for advertisements and notices, of civil records filed in state and community archives, of business account-books and records that have been preserved, and of business directories of the period under consideration. In addition, such a study would require the compilation of an inventory of all surviving instruments in private and public collections, and a correlation of all the data that could be assembled from these sources.

The present study attempts only in part to accomplish this aim, being no more than a preliminary compilation of the scientific instruments known to have been used during the first two centuries of American colonial existence. It merely attempts to assemble all the data that is presently available in scattered sources, and to organize it in a usable form for the student and historian of American science. A supplement relating to 19th-century instruments and instrument makers is in progress.

The most that is hoped for the present work is that it will be of temporary assistance, serving to bring forth additional information on the subject from sources not previously available or known.

EARLY AMERICAN SCIENTIFIC INSTRUMENTS

and Their Makers

The Tools of Science

Philosophical and Practical Instruments

Development of the sciences in the American Colonies was critically dependent upon the available tools--scientific instruments--and the men who made and used them. These tools may be separated into two groups. The first group consists of philosophical instruments and scientific teaching apparatus produced and employed for experimentation and teaching in educational institutions. The second includes the so-called "mathematical instruments" of practical use, which were employed by mathematical practitioners and laymen alike for the mensural and nautical needs of the Colonies. It is particularly with this second group that the present study is concerned.

It has been generally assumed that scientific instruments, as well as the instrument makers, of the first two centuries of American colonization were imported from England, and that the movement declined by the beginning of the 19th century with the development of skilled native craftsmen. This assumption is basically true for those instruments grouped under philosophical and scientific apparatus for experimentation and teaching. Almost all of these items were in fact imported from England and France until well into the 19th century.

Likewise, the very earliest examples of mathematical instruments for surveying and navigation in the Colonies were imported with the settlers from England. It was not long after the establishment of the first settlements, however, that the settlers, and later the first generation of native Americans, began to produce their own instruments. Records derived from historical archives and from the instruments themselves reveal that a considerable number of the instruments available and used in the Colonies before 1800 were of native production. Apparently, relatively few instrument makers immigrated to the American continent before the end of the Revolutionary War. Later, with the beginning of the 19th century, makers of and dealers in instruments in England and France became aware of the growing new market, and emigrated in numbers to establish shops in the major cities of commerce in the United States.

Quite possibly the few instrument makers trained in England who immigrated to the Colonies in the early epoch of Colonial development may have in turn trained others in their communities, although no evidence has yet been found. Perhaps more data on this aspect of the subject will eventually come to light.

There is reason to believe that a few mathematical practitioners and instrument makers lived and worked in the New England colonies as early as the first century of colonization.
