Alexander Dessler

Alexander J. Dessler (born October 21, 1928) is a space scientist known for conceiving the term heliosphere and for founding the first Space Science Department in the United States.

Early life and education

Dessler was born on October 21, 1928, in San Francisco, California and received a B.S. in physics from the California Institute of Technology in 1952 and a Ph.D in Physics from Duke University in 1956. His PhD thesis was "The amplitude dependence of the velocity of second sound" under William M. Fairbank.

Career

Dessler began his career at Lockheed Missiles and Space Company. In 1963, while at the Southwest Center for Advanced Studies, now University of Texas at Dallas, he was recruited by Rice University president Kenneth S. Pitzer to found the world's first university "Space Science" department, as a response to President John F. Kennedy's Moon Speech, delivered at Rice on September 12, 1962. The Department was the first truly multidisciplinary department in the University, bringing together Astronomy, Atmospheric Science Space Physics, Planetary Science, Atomic and Molecular Physics.

He is emeritus professor of Space Physics and Astronomy at Rice University, active from 1963 to 1992. His research subject areas are magnetospheric physics, planetary magnetospheres, primarily of Jupiter and planetary science. He was founding chair of the Department of Space Science at Rice University, later known as the Department of Space Physics and Astronomy.
Dessler served three terms as chair of the department and retired in 1992. During that interval, from 1982 to 1986 he was Director of the Space Science Laboratory at NASA's Marshall Space Flight Center.

His educational innovations include the use of Keller-method inquiry-based self-paced instruction starting in 1970 and was instrumental in encouraging women and minorities in science.

In 1993, Dessler became Senior Research Scientist at the Lunar and Planetary Laboratory, University of Arizona, until 2007. He is retired and an adjunct professor of Space Physics at Texas A & M University.

At the ''Possible Relationships Between Solar Activity and Meteorological Phenomena'' symposium, Goddard Space Flight Center, November 7–8, 1973, Charles Greely Abbot's lifelong work on solar activity provided the foundation for research as a possible driver for Earth weather. In addressing the topic, A. J. Dessler commented that any increased energy received in Earth's troposphere due to increased solar activity is negligible, and that correlations alone do not establish causation. The challenges facing scientists with complex systems like the planet's weather require finding a coupling mechanism. He suggested to continue seeking physical mechanisms.

In 2004, Dessler refuted the proposition put forth by retired NASA scientist Addison Bain concerning the causes and combustion of the Hindenburg disaster. Dessler described Bain's incendiary paint theory as flawed science based on the stoichiometry of the coating's composition, the very slow burn rate of the metallic coating of the airship, and the lack of a high enough energy source to ignite the coating.

Personal life

Dessler and his wife, Lorraine, were married for almost 70 years before her death in November 2021. They had four children, including Texas A & M atmospheric scientist Andrew Dessler.
