From a Between the Lines (Washington St. Library) Blog Post by Rand Simmons:
History Makers is a biographical database of Washington elected officials and activists from territorial times to present. Each individual’s entry includes a photograph, links, and basic biographical information, for example, occupations, offices, affiliations, birth and death dates, and marriage information. To date: Governors, Lieutenant Governors, Secretaries of States, Treasurers, U.S. Senators and U.S. Representatives are included. This resource is made possible by dedicated volunteers and will continue to be updated.
