Ernst Kunibert Zinner (30 January 1937 – 30 July 2015) was an Austrian astrophysicist, known for his pioneering work in the analysis of stardust in the laboratory. He came to the United States in the 1960s for graduate work, earning his doctorate at Washington University in St. Louis. He conducted much of his academic and research career in European universities, in addition to American institutions.
Personal life
Zinner was born on 30 January 1937[citation needed] at Sankt Peter in der Au, Austria,[1] a small town about 100 miles west of Vienna. Although his father, Kunibert Zinner, was a renowned sculptor, Ernst was more interested as a boy in nature and science.[1] Zinner had four younger siblings, and relatives in Austria.
He married Brigitte Wopenka and they had a son, Max Giacobini Zinner. The son now lives in New York City.[2]
Education and career
Zinner obtained an undergraduate degree in physics from the Vienna University of Technology and started working. In the mid-1960s, he moved to St. Louis to attend Washington University for graduate work. He earned his Ph.D. there in 1972 in high energy physics.[2][3][4]
He then held positions at:
- Max Planck Institute for Nuclear Physics (1980)[4]
- Vienna University of Technology (1980–82)[4]
- University of Pavia (1989)[4]
- University of Bern (1994)[4]
- Australian National University (1995)[4]
- Max Planck Institute for Chemistry (2001, 03, 04)[4]
- National Museum of Natural History (France) (2006)[4]
- Carnegie Institution for Science (2010)[4]
- University of Perugia (2011)[4]
- University of Granada (2013)[4]
Zinner subsequently joined the Laboratory for Space Sciences, part of the McDonnell Center for Space Sciences at Washington University in St. Louis in 2014. He continued to work there for the rest of his career, becoming a Research Professor of Physics and Earth and Planetary Sciences. Zinner retired early in 2015.[2][3]
Zinner was a member of the American Association for the Advancement of Science, the American Geophysical Union, and Sigma Xi. He was also a fellow of the American Physical Society, the Meteoritical Society, the Geochemical Society, and the European Association of Geochemistry.[3]
Zinner had Mantle Cell Lymphoma for the last 19 years of his life. He died on 30 July 2015 at the age of 78.[2]
Legacy and honors
After his death, friends and colleagues established an "Ernst Zinner Scholarship Fund" to support cello students at Webster University.[2]
Research
Zinner's PhD research was in high energy physics. He subsequently studied the effects that the environment within our solar system would have on the moon and the parent bodies of meteors, using nuclear particle tracks, micrometeoid craters, and elements in the solar wind. His later research was focused on the information contained in presolar grains carried by early meteorites. These grains were formed in atmospheres and explosions of stars outside of earth's solar system. They can provide information about the history of stellar nucleosynthesis and the formation of the solar system.[3]
Zinner was instrumental in identifying, for the first time, material in meteorites that pre-dated the formation of the solar system 4.6 billion years ago.[5][6] Zinner and his colleagues found minute amounts of stardust - diamond and silicon carbide - that originated outside the solar system.
Identification of these grains involved a measurement technique called secondary ion mass spectrometry (SIMS). Zinner was widely considered one of the leading authorities on the instrument,[1] and he trained scientists worldwide in its use. The work led to the emergence of a new field of study, the laboratory analysis of stardust,[7] which opened up new insights into the evolution of stars and nucleosynthesis of the elements.
Since 1974, Zinner's research has involved Ion microprobe analysis. He has worked with the Cameca IMS 3f instrument since 1982, and the Cameca NanoSIMS instrument since 2000.[3] He led the Long Duration Exposure Facility.[3]
