The DIRECTORY OF AMERICAN TOOLMAKERS, also known as The DAT, is the product of a major project undertaken by the membership of the Early American Industries Association – the compilation of a comprehensive guide to commercial toolmakers in North America, including the United States and Canada, before 1900.
Utilizing markings from tools, primary source materials such as period directories and advertisements as well as secondary sources supportive of historical research, more than 250 volunteers sifted and compiled the data to produce the list of approximately 14,000 toolmakers. In addition to the primary list, the DIRECTORY OF AMERICAN TOOLMAKERS also includes a list of those toolmakers who did not meet all of the criteria of the main list as well as any related patents and patent holders.
Included on the CD are:
- The DIRECTORY OF AMERICAN TOOLMAKERS in fully searchable PDF format
- An Index and Introduction linked to the PDF for ease of navigation
- Three sample articles from The Chronicle of the Early American Industries Association
