In Memoriam: Donald L. Schilling: June 11, 1935–November 30, 2022

The communications engineering community was saddened in late November, 2022 by the death of one of the great contributors to 20th century (and 21st century) communications technology. Don Schilling, a leading educator, ComSoc volunteer including serving as President, adviser to U.S. government, and entrepreneur as well as researcher, significantly advanced spread spectrum techniques and applications. He graduated many students who became important contributors themselves. In addition to his technical contributions, Don was a dedicated husband and father, and a warm and generous friend to his students and to many of us who were his colleagues.
