Introduction | Agency History | Scope and Contents | Series Description | Inventory


The records of the International Association of Heat and Frost Insulators and Asbestos Workers, Local 45, Toledo, Ohio, date from 1916-1978. The history of this local labor union is reflected in the collection which consists of one linear foot of correspondence, agreements, and financial records.

The records of the Asbestos Workers, Local 45, were donated to the Center for Archival Collections in September 1980, with the cooperation of Jerry Hall, Business Agent for Local 45. Literary and property rights have been dedicated to the public and duplication is permitted for the purposes of preservation and scholarly research. The register was drafted by Jill Morse, a graduate student at Bowling Green State University, in May 1981, and edited and revised in July 1988, by Susan Hughes, a manuscript processor employed through a grant provided by the Ohio Historical Society.

Agency History

The purpose of the Asbestos Workers Union, according to the constitution is to: "defend by all legal and honorable means the rights of its membership, to advance their interests as working men, to develop opportunities for employment in the trade, and by education and cooperation to raise them to that position in society to which they are justly entitled.

Local 45 of the Asbestos Workers originated in the 1920's. Membership remained very small until after World War II when a marked increase in membership began.

The researcher may wish to contact Local 45, at its present (1997)office, 1837 West Alexis Road, Suite #2, Toledo, Ohio 43613-2302, for further information. Mr. Gerald R. Hall serves as Business Manager.

Scope and Content

The records of Asbestos Workers, Local 45 document the history of this labor union from 1916 to 1978. This collection consists primarily of correspondence, agreements, and financial records. The collection may be of marginal use for the labor historian or the genealogist, seeking simple verification of names or dates.

Individually, a study of the correspondence of this collection is not particularly revealing. It consists primarily of financial form letters from the International's Secretary-Treasurer acknowledging receipt of various financial reports. There is also some correspondence from the Toledo Central Labor Union consisting of meeting announcements, notices of upcoming events, or brief surveys of meetings. This collection does not include any union minutes; whether lost or destroyed, it is not certain.

Agreements between the Asbestos Workers and the Master Insulators Association are complete from 1968 to 1980. Financial records are relatively complete from the late 1930s to around 1950. This collection's use, however, is limited by the absence of important records.
