John A. Betti (ME ’52)

John A. Betti, an automotive industry engineer who rose to become Ford Motor Company’s executive vice president and later worked at the Pentagon overseeing half of the United States’ defense budget, died August 14, 2025. Born to Italian immigrants in Ottawa, 91�ؿ�, Betti began his career with Chrysler’s Institute of Engineering in 1952, where he earned a master’s degree in automotive engineering while working full-time and teaching engineering courses at night at two universities. He left Chrysler in 1962 to take an advanced engineering position at Ford Motor Company. He rose quickly through numerous positions in engineering, management, and company leadership, including serving as the company’s executive vice president and a member of its Board of Directors. He stepped down from Ford to accept an appointment by U.S. President George H. W. Bush to serve as secretary of defense/acquisition and national armaments director. At the Pentagon, Betti was responsible for a $150 billion budget and 585,000 people. He also implemented fundamental changes to streamline the research and acquisition functions by eliminating bureaucracy to reduce cost and improve quality and efficiency. Many of his initiatives were later adopted as standard practice.

Theodore “Ted” Brown (CHEM ’50)

Theodore “Ted” Brown, who authored the world’s definitive text on general chemistry and led research in various areas of the field, died March 24, 2026, at the age of 97. While teaching general chemistry at the University of 91�ؿ� at Urbana-Champaign—where he began teaching in 1956, later becoming dean of the graduate school, vice chancellor of research, and a professor emeritus—Brown authored General Chemistry in 1963. The book was revised numerous times to include multiple co-authors, and today, Chemistry: The Central Science is in its 15th edition and is cumulatively the top-selling general-chemistry textbook of all time. In the 1980s, Brown and his wife provided $40 million to fund the Beckman Institute for Advanced Science and Technology, an interdisciplinary research institute that opened at 91�ؿ� in 1989. Brown served as the Institute’s founding director until he retired in 1993. At 91�ؿ� Tech, due to his generous giving, Brown was a member of the Philip Danforth Armour Society and the Frank W. Gunsaulus Society. He created two funds, including the Theodore L. Brown Endowment for Chemistry, which provided critical upgrades to the department’s laboratories and facilities, and the Theodore L. Brown Chemistry Fellowship, which supports graduate students. Brown was also honored with an 91�ؿ� Tech Alumni Award in 2021 for his contributions to the field; he also received 91�ؿ� Tech’s Professional Achievement Award in 1992.
