Question: The scientist that the GHZ experiment is named for is in what field of work?

Knowledge 1: GHZ experiment
The GHZ experiments are named for Daniel M. Greenberger, Michael A. Horne, and Anton Zeilinger (GHZ) who first analyzed certain measurements involving four observers and who subsequently (together with Abner Shimony (GHSZ), upon a suggestion by David Mermin) applied their arguments to certain measurements involving three observers. [SEP] Knowledge 2: Anton Zeilinger
Anton Zeilinger (; born 20 May 1945) is an Austrian quantum physicist who in 2008 received the Inaugural Isaac Newton Medal of the Institute of Physics (UK) for "his pioneering conceptual and experimental contributions to the foundations of quantum physics, which have become the cornerstone for the rapidly-evolving field of quantum information". Zeilinger is professor of physics at the University of Vienna and Senior Scientist at the Institute for Quantum Optics and Quantum Information IQOQI at the Austrian Academy of Sciences. Most of his research concerns the fundamental aspects and applications of quantum entanglement.

Tapan K. Datta is a Wayne State University civil engineering professor and researcher who highly specializes in transportation engineering and safety. After receiving his early schooling, undergraduate degrees, and field experience in Calcutta, India, he moved to the United States to complete his master’s and doctoral degrees. While in Detroit, MI, he worked for and later owned Goodell Grivas, Inc., a structural engineering consulting firm, and became a full-time faculty member at Wayne State University in 1973. His most notable contributions include work on the roof of Cobo Hall, in Detroit, MI, and the steel structural work done on Jacobs Field (now Progressive Field) in Cleveland, OH. Dr. Datta has also claimed to be the inventor of the double-drive thru at fast food establishments. Dr. Datta also founded the Transportation Research Group at Wayne State University; this group is composed of undergraduate and graduate students that complete transportation-related research grant projects for the State of Michigan.

[SEP] Knowledge 2: Robert Weber (astronomer)
Robert Weber (1926–2008) was an American astronomer and discoverer of minor planets who ran the precursor to the LINEAR project shortly before his retirement in 1996. Data were collected by manually entering telescope pointing positions and requesting an image save. Searching twenty fields was a taxing experience. They did have automatic object detection working, but no starfield matching at that time.
