Claire Kelly Schultz (November 17, 1924 - May 28, 2015) was a leading figure in the early development of automated information retrieval systems and information science. A "documentalist", she was particularly known for her work in thesaurus construction and machine-aided indexing, innovating techniques for punch card information retrieval. While working as a librarian at the Merck, Sharp and Dohme chemical company she "developed a machine-sorted card system that employed Boolean retrieval logic. Her first use of punched cards in 1949 used the Mooers Zator system." This has been seen as a "transitional role of such punched-card systems toward later use of computers for information retrieval".
