Reference excerpt

Hans Michael Mark (June 17, 1929 – December 18, 2021) was a German-born American government official who served as Secretary of the Air Force and as a Deputy Administrator of NASA. He was an expert and consultant in aerospace design and national defense policy. Mark retired from the Department of Aerospace Engineering and Engineering Mechanics at the University of Texas at Austin's Cockrell School of Engineering in July 2014.

Early life and career Mark was born in the city of Mannheim, Baden, Germany. He lived in Vienna for a time before escaping the Nazi Anschluss via Switzerland. Before the collapse of France the Mark family moved to London. Mark's father, Herman Francis Mark, a prominent polymer chemist, secured a position with a Canadian paper company and left before the family could accompany him. Finally, in late 1939, his family joined him in Hawkesbury, Ontario. About a year later the family moved to the United States, settling in the Flatbush section of Brooklyn, New York after the elder Mark accepted a professorship at the Polytechnic Institute of Brooklyn. After becoming an American citizen in 1945, he graduated from New York's selective Stuyvesant High School in 1947. He went on to receive a bachelor's degree in physics from the University of California, Berkeley (where he was a member of Sigma Pi fraternity) in 1951. He then earned a Ph.D. in physics from the Massachusetts Institute of Technology in 1954. After receiving his doctorate, Mark stayed on at MIT as a research associate and acting head of the Neutron Physics Group Laboratory for Nuclear Science. He returned to UC Berkeley in 1955 and remained there until 1958 as a research physicist at the university's Lawrence Radiation Laboratory in Livermore, California. Mark then returned to MIT as an assistant professor of physics. In 1960, he again returned to the University of California's Livermore Radiation Laboratory's Experimental Physics Division. He remained there until 1964, when he became chairman of the university's Department of Nuclear Engineering and administrator of the Berkeley Research Reactor. Mark also taught undergraduate and graduate courses in physics, engineering and management at Boston University, the University of California, Davis and Stanford University.

U.S. government In February 1969, he became director of NASA's Ames Research Center, located in Mountain View, California. In this role, he managed the center's research and applications efforts in aeronautics, space science, life science, and space technology. He subsequently served as Under Secretary of the Air Force from 1977 until July 1979, when he was promoted to Secretary of the Air Force. Concurrently, he served as Director of the then-classified National Reconnaissance Office from August 1977 to October 1979. He remained at this position until 1981, when he was appointed Deputy Administrator of NASA by President Reagan, a position he served in from July 10, 1981, to September 1, 1984. He later returned to the Pentagon in 1999–2000 to serve as Director of Defense Research and Engineering (DDR&E).

University of Texas

Upon leaving NASA in 1984, Mark served as Chancellor of the University of Texas System until 1992. He moved on to become a senior professor of aerospace engineering at the University of Texas at Austin. In July 1998, he began work at The Pentagon upon President Clinton's nomination of him as Director of Defense Research and Engineering. In 2001, he returned to the University of Texas at Austin, where he held the John J. McKetta Centennial Energy Chair in Engineering as a professor in the Department of Aerospace Engineering and Engineering Mechanics and held a research position at the University of Texas' Applied Research Laboratories. Mark retired from the faculty of the University of Texas at Austin on July 1, 2014. He was voted by the Regents of the university as a Professor Emeritus of Aerospace Engineering and Engineering Mechanics.

Honors

Mark was a member of the National Academy of Engineering, the nation's highest honor for engineering professionals. He was awarded the Robert Henry Thurston Lecture Award from the American Society of Mechanical Engineers in 1982. He was also an Honorary Fellow of the American Institute of Aeronautics and Astronautics. He received the 1999 Joe J. King Engineering Achievement Award and the 1999 George E. Haddaway Medal for Achievement in Aviation. Dr. Mark was honored for his contributions to the U.S. military space program at the 2006 annual meeting of the American Astronautical Society. He received the 2006 Military Astronautics Award on November 14, 2006, at the society's annual meeting in Pasadena, California. In 2008, the Space Foundation awarded Mark its highest honor, the General James E. Hill Lifetime Space Achievement Award. It is presented annually to recognize outstanding individuals who have distinguished themselves through lifetime contributions to the welfare or betterment of humankind through the exploration, development and use of space, or the use of space technology, information, themes or resources in academic, cultural, industrial or other pursuits of broad benefit to humanity. In 2012, the Air Force Space Command awarded him the Air Force Space and Missile Pioneers Award. The award recognizes individuals for their significant role in the history of Air Force space and missile programs.

Later life and death Mark died from progressive dementia in Austin, Texas, on December 18, 2021, at the age of 92. He is survived by his daughter, Jane Mark, his son Rufus Mark, his grandchildren, Rob and Rixana Jopson, and Phillip, Nick, and Juliette Mark, and his great-granddaughter Julianna Mark.

Publications Dr. Mark authored or edited eight books and published more than 180 technical reports. His works include:

(co-authored) Adventures in Celestial Mechanics (co-authored) Encyclopedia of Space and Technology The Space Station: A Personal Journey (Duke University Press, 1987) The Management of Research Institutions (NASA SP-481, 1984) (co-authored) Experiments in Modern Physics and Power and Security (co-authored) The Properties of Matter Under Unusual Conditions An Anxious Peace: A Cold War Memoir (Texas A&M University Press, 2019)

Worked examples

Example 1 — a first encounter with Hans Mark

Start with the simplest possible case. Write down what Hans Mark claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Hans Mark before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Hans Mark ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Hans Mark

In research
Hans Mark appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Hans Mark in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Hans Mark is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1929 births, 2021 deaths, Carter administration personnel, so understanding it makes those chapters shorter.
In everyday life
Look for Hans Mark outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
