## Why They Matter
Lyle H. Ungar’s significance in computer science is anchored in his role as an academic researcher and doctoral advisor whose mentorship contributed to the training of researchers who became influential in the field. By supervising doctoral students such as Charles Ling and David C. Parkes, Ungar helped transmit expertise and methods that those students carried into their own research and academic careers. His publications and research outputs are discoverable across multiple, widely used scholarly indices (dblp, Google Scholar, Semantic Scholar, Scopus, Math Reviews, zbMATH), ensuring that his work is accessible, citable, and woven into the scholarly record. The presence of authoritative identifiers (ISNI, VIAF, GND, Library of Congress) further stabilizes the bibliographic trail of his contributions. Without such mentoring and scholarly production, the academic lineage and some lines of research that his students pursued would have been different; his role has therefore contributed to the propagation and continuity of research in computer science through both publications and trained researchers.
