Norman Hackerman (1912–2007): The Architect of Corrosion Science and Academic Excellence
Norman Hackerman was a rare breed of scholar: a world-class physical chemist who possessed the administrative acumen to reshape the landscape of American higher education. Over a career spanning seven decades, Hackerman redefined our understanding of how metals interact with their environments while simultaneously guiding two of Texas’s premier institutions—the University of Texas at Austin and Rice University—into the top tier of global research universities.
1. Biography: From Baltimore to the Lone Star State
Born on March 2, 1912, in Baltimore, Maryland, Norman Hackerman was the son of Jewish immigrants. He remained in his hometown for his education, attending Johns Hopkins University, where he earned his B.A. in 1932 and his Ph.D. in chemistry in 1935.
His early career was a mosaic of industrial and academic roles. He taught at Loyola College and worked for the U.S. Coast Guard as an assistant chemist. During World War II, his expertise in surface chemistry led him to the Manhattan Project. Working with the Kellex Corporation, he contributed to the development of the gaseous diffusion process used to separate uranium isotopes—a task that required a deep understanding of how gases interact with solid barriers.
In 1945, Hackerman joined the faculty of the University of Texas at Austin (UT). His ascent was meteoric: he became a full professor in 1950, Chairman of the Chemistry Department in 1952, and eventually served as the President of UT Austin from 1967 to 1970. In 1970, he was recruited to become the President of Rice University, a position he held until 1985. Even after "retiring," he remained an active researcher and served as the Chairman of the Scientific Advisory Board of the Robert A. Welch Foundation until his death in 2007.
2. Major Contributions: The Science of "Passivity"
Hackerman’s scientific legacy is rooted in electrochemistry and surface chemistry, specifically the study of corrosion. Before Hackerman, corrosion was often treated as an inevitable engineering nuisance. He transformed it into a rigorous molecular science.
- Corrosion Inhibition: Hackerman was a pioneer in understanding how organic molecules could be used to prevent the oxidation of metals. He developed the theory that certain molecules form a "monomolecular layer" (a coating one molecule thick) on a metal surface, effectively blocking the electrochemical reactions that cause rust and decay.
- The Concept of Passivity: He performed foundational work on "passivity"—the state in which a metal becomes resistant to corrosion due to the formation of a thin, protective oxide film. His research helped define the conditions under which this film remains stable.
- Electrochemical Kinetics: He refined the methodologies for measuring the rate of electron transfer between a metal surface and an electrolyte, which is the fundamental process driving both batteries and corrosion.
3. Notable Publications
Hackerman authored or co-authored over 200 archival publications. His work was characterized by a focus on the interface between the solid metal and the liquid environment.
- "The Adsorption of Aliphatic Amines on Iron" (1955): A seminal paper in the Journal of the Physical Chemistry that detailed how amines (nitrogen-containing compounds) stick to iron surfaces to inhibit acid corrosion.
- "Passivity of Metals" (1962): Published in the Journal of the Electrochemical Society, this work remains a cornerstone for understanding the protective layers on stainless steel and other alloys.
- "Effect of Anions on the Kinetics of Iron Corrosion" (1970): This research explored how different ions in water (like chlorides) accelerate or decelerate the breakdown of metals.
4. Awards & Recognition
Hackerman’s contributions to science and policy earned him the highest honors available to an American scientist:
- National Medal of Science (1993): Awarded by President Bill Clinton for his "vital contributions to the understanding of corrosion and for his visionary leadership in science policy."
- Vannevar Bush Award (1984): The National Science Board’s highest honor for contributions to the nation through public service.
- The Edward Goodrich Acheson Award (1984): From the Electrochemical Society.
- The Palladium Medal (1965): One of the most prestigious awards in electrochemistry.
- Honorary Doctorates: He received numerous honorary degrees, including ones from Johns Hopkins, TCU, and St. Edward’s University.
5. Impact & Legacy: Building the "Research Triangle" of Texas
While his chemistry was influential, Hackerman’s legacy as an administrator is arguably more profound.
- Institutional Growth: At UT Austin, he navigated the turbulent student protests of the late 1960s while maintaining a focus on faculty excellence. At Rice, he is credited with transitioning the university from a respected regional college into a world-class research institution, overseeing the founding of the Jones Graduate School of Business and the expansion of the humanities and sciences.
- The Welch Foundation: As chair of the Welch Foundation’s advisory board for 25 years, he directed hundreds of millions of dollars in grants to chemistry researchers across Texas. This funding is largely responsible for making Texas a global hub for chemical research.
- National Science Policy: Hackerman served two terms on the National Science Board (the governing body of the NSF), including a stint as chairman (1974–1980), where he was a fierce advocate for federal funding of basic, "blue-sky" research.
6. Collaborations & Mentorship
Hackerman was known for his "Hackerman Group" at UT, which produced several generations of electrochemists.
- Key Colleagues: He worked closely with R.J. Speer and A.C. Makrides in his early years to establish the mechanisms of adsorption.
- Mentorship: He supervised over 60 Ph.D. students and dozens of post-doctoral fellows. His students often remarked on his "Socratic" style of leadership—he rarely gave answers, instead asking the right questions to lead the student to the solution.
7. Lesser-Known Facts
- The Fencing Master: Hackerman was an elite fencer. He was the captain of the Johns Hopkins fencing team and later coached the fencing team at the University of Texas while serving as a professor. He often applied the logic of the sport—precision, timing, and strategy—to his administrative work.
- A "Working" Retirement: Hackerman famously never stopped working. Even in his 90s, he maintained an office at UT Austin and went in daily. He was known for his "open-door policy," where a freshman student could walk in and debate science with him just as easily as a dean.
- The Hackerman Building: In 2010, UT Austin dedicated the Norman Hackerman Building (NHB), a $185 million experimental science facility. It stands as a literal and figurative monument to his belief that the future of science lies in interdisciplinary collaboration.
Norman Hackerman’s life was a testament to the idea that the "ivory tower" and the "laboratory bench" are not mutually exclusive. He protected the infrastructure of the world from corrosion while building the academic infrastructure that would train the scientists of the next century.
