Feinler joined SRI International in 1960, marking her transition from biochemistry into the emerging field of information science.
In 1960, Elizabeth Feinler joined SRI International (then known as Stanford Research Institute), an independent nonprofit research institute in Menlo Park, California. This marked a pivotal career shift away from her academic training in biochemistry toward the nascent field of information science and computing.
At the time, SRI was becoming a hub for cutting-edge technological research, including work that would eventually contribute to the development of the ARPANET, the precursor to the modern internet. Feinler's background in chemistry and her skills in organizing and classifying complex scientific literature made her uniquely suited to information science work, which was just beginning to formalize as computers started handling ever-larger datasets.
Her early years at SRI involved work on information retrieval systems, chemical literature indexing, and documentation projects, which built the foundation of skills she would later apply to organizing the ARPANET's growing network of connected computers and users. This period represents the quiet beginning of a career that would eventually place her at the center of the internet's foundational infrastructure.
Though the exact month and day of her joining SRI are not documented in available sources, 1960 marks the beginning of a professional relationship that would span nearly three decades and result in her most historically significant contributions to computer networking, including her later leadership of the Network Information Center.
