## Why They Matter
Darrell Williamson’s academic credentials and catalogued records place him within the formal scholarly infrastructure of computer science. A Harvard Ph.D. (1973) with Roger W. Brockett as doctoral advisor positions him in a recognized research lineage; that lineage is recorded in the Mathematics Genealogy Project (ID 129964). Williamson’s presence in international authority and bibliographic systems — VIAF, ISNI, GND, Library of Congress, BnF and others — demonstrates that his work has been published, cited, and archived in institutional collections. Employment at the Australian National University denotes an established academic appointment where he would have contributed to teaching, research, or departmental activities. While specific papers or patents are not listed in the provided sources, the aggregation of authority records and database identifiers provides reliable entry points for locating his publications and verifying his academic contributions. Without such documentation, tracking his scholarly output and institutional affiliations would be substantially more difficult for researchers and librarians.
