MACOMB/MOLINE, IL - - Former Professor of Western Illinois University Robert Wayne Jefferson, 86, of Macomb, a distinguished educator, scholar and academic leader, passed away March 25, leaving behind a legacy of more than four decades in higher education.
Born on June 5, 1939, in Davenport, IA, to Lewis and Virginia Jefferson. He grew up on a farm in Central Iowa, where he developed a strong work ethic that would guide him throughout his life. He married Sally Ann Wallace on June 11, 1961, in Reinbeck, IA. She survives.
Robert and his wife Sally Ann settled in Macomb 1960 to raise their children and embark on a long and distinguished 41 years career in university teaching, scholarship and administration, beginning in 1965 on the College of Business faculty at WIU, where he taught advertising, survey research, industrial marketing and MBA courses, earning a reputation as a dedicated professor and mentor who challenged and inspired his students.
Throughout his career at WIU, Professor Jefferson held several leadership roles, including serving as Chair of the Marketing and Finance Department, Dean of the College of Business and Associate Provost. His leadership helped shape the university's business programs and strengthen its academic reputation.
