Alexander J. Dessler

Alexander J. Dessler (October 21, 1928 – April 9, 2023) was an American 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.

Dessler was 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.

In 1993, Dessler became senior research scientist at the Lunar and Planetary Laboratory, University of Arizona, until 2007. He was retired and an adjunct professor of Space Physics at Texas A & M University.

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 and death 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.

Dessler died in Bryan, Texas on April 9, 2023, at the age of 94.

This also was the occasion of being named Fellow of the American Geophysical Union 1984 - Soviet Geophysical Committee, Medal for Contributions to International Geophysics 1988 - Rotary National, Stellar Award for Academic Development 1993 - American Geophysical Union, John Adam Fleming Medal Winner 1996 - Royal Swedish Academy of Sciences, Foreign Member 2003 - American Geophysical Union, William Kaula Award 2015 - National Academy of Sciences, Arctowski Medal
