making in an apartment. In the ensuing years they had two daughters, Judy (1940) and Jeane (1946).
Donald Berry’s professional career was devoted to education and research in traffic and transportation engineering. After spending 12 years as a transportation engineer and then director of the Traffic Division at the National Safety Council in Chicago, he embarked on a career in academia. As a professor, he helped organize graduate programs in transportation engineering at the University of California, Berkeley (seven years), Purdue University (two years), and Northwestern University (22 years). The 10 to 15 M.S. and 2 to 4 Ph.D. graduates each year from Northwestern University went on to occupy many key positions in federal, state, and local transportation agencies, on university faculties, and in consulting firms. From 1962 to 1968, Don was chairman of the Department of Civil Engineering at Northwestern. Over the years, he directed in-service training programs in traffic and transportation engineering in many parts of the United States and several foreign countries, including Venezuela, Spain, South Africa, Thailand, Israel, and the Philippines.
Even before Don Berry became a university professor, he was an educator. During World War II, he was selected by the FBI to teach courses in major cities throughout the country on controlling transportation and traffic in the event of blackouts, air raids, or wartime damage. Later he worked in Washington for the Office of Civil Defense.
Don always brought the practical world of transportation into the classroom. He was a teacher who made every academic concept real and established bridges linking research to practice. He built cooperative education programs connecting the university to key public agencies, allowing students to finance and broaden their education by working at these agencies and conducting research as a part of their work. He strongly encouraged his students to join and participate in the activities of professional societies, including attendance at meetings of the Institute of Traffic (now Transportation) Engineers (ITE) and Transportation (formerly Highway) Research Board (TRB).
Don created a family of graduate students whom he nurtured to professional maturity, setting academic, professional, and
