Question: Which of the following, Albert Einstein or Pete Dexter, was a theoretical physicist from Germany?
Context: Albert Einstein (14 March 1879 – 18 April 1955) was a German-born theoretical physicist.  Einstein developed the theory of relativity, one of the two pillars of modern physics (alongside quantum mechanics).  Einstein's work is also known for its influence on the philosophy of science.  Einstein is best known by the general public for his mass–energy equivalence formula "E" = "mc" (which has been dubbed "the world's most famous equation").  He received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect", a pivotal step in the evolution of quantum theory. Helen Dukas (17 October 1896 – 10 February 1982) was Albert Einstein's secretary.  She also co-authored "" and co-edited "Albert Einstein: The Human Side" with Dr. Banesh Hoffmann.  Dukas was one of two trustees chosen by Einstein, according to his Last Will and Testament, to hold the literary rights to all of his manuscripts, copyrights, publication rights, royalties, and royalty agreements.  The other trustee was the economist Dr. Otto Nathan.  In short, Dukas and Dr. Nathan were the "executors of his literary heritage."  They collaborated on the compilation of "The Collected Papers of Albert Einstein," using documents that were subsequently donated to the Hebrew University of Jerusalem. The Albert Einstein Science Park is located on the hill Telegrafenberg in Potsdam, Germany.  The park was named after the physicist Albert Einstein.  The best known buildings in the park are the Einstein Tower, an astrophysical observatory that was built to perform checks of Einstein's theory of General Relativity; and the Great Refractor of Potsdam, which today belong to the Astrophysical Institute Potsdam.  These buildings, along with various astronomical, meteorological, and geophysical observatories were integrated into an English country garden. Illana Katz (born 1948) is an author, lecturer, and founder of Real Life Storybooks, a publisher of special needs storybooks for children.  Motivated by the late 1980s news that her son Seth had autism, Katz began to educate herself about autism, including researching into the life of theoretical physicist Albert Einstein.  After writing "Joey and Sam: A Heartwarming Storybook About Autism, a Family, and a Brother's Love" in 1993, circumstances led Katz to write "Sarah", a 1994 book about child molestation.  By 1995 Katz and her collaborator, UCLA professor Dr. Edward Ritvo, had gathered enough material to write their 1995 book, "In a World of His Own: A Storybook About Albert Einstein", in which they concluded that Einstein did have autism.  Katz continues to work in the special needs profession. The "Albert Einstein" ATV, or Automated Transfer Vehicle 004 (ATV-004), was a European unmanned cargo resupply spacecraft, named after the German-born physicist Albert Einstein.  It was built to supply the International Space Station (ISS) with propellant, water, air, and dry cargo, and also to reboost the station's altitude with its thrusters.  It was the fourth and penultimate ATV to be built, following the "Edoardo Amaldi", which was launched in March 2012.  "Albert Einstein"<nowiki>'</nowiki>s components were constructed in Turin, Italy, and Bremen, Germany, and underwent final assembly and testing in Bremen in 2012.  The spacecraft left Bremen for Kourou on 31 August 2012 to begin launch preparations. The Albert Einstein Peace Prize is/was a peace prize awarded annually since 1980 by the Albert Einstein Peace Prize Foundation.  The Foundation dates from 1979, the centenary of the birth of Albert Einstein, and evokes the Russell–Einstein Manifesto which urges nuclear disarmament.  It was established, with the sponsorship of the trustees of Einstein's estate, by William M. Swartz (1912–87) a wealthy businessman and the grandfather of activist Aaron Swartz.  William M. Swartz was involved in the Pugwash Conferences on Science and World Affairs and established the Foundation in part to support Pugwash.  Prize winners, mainly active in nuclear disarmament, receive(d) $50,000. This award should not be confused with many others named after the famous physicist, such as the Albert Einstein World Award of Science given by the World Cultural Council (since 1984), the Albert Einstein Medal given by the Albert Einstein Society (since 1979), nor with the Hans Albert Einstein Award, named after his son and given by the American Society of Civil Engineers (since 1988).  It was established much earlier than these, when Einstein was still alive and was a professor at the Institute for Advanced Study.  It has been called "the highest of its kind in the United States" by "The New York Times".  Some considered it as "the prestigious equivalent of a Nobel Prize". Pete Dexter (born July 22, 1943) is an American novelist. Albert Einstein Square (Kikar Albert Einstein) is a public square in Jerusalem, Israel, named for the physicist Albert Einstein.  It is located in the Kiryat Shmuel neighborhood, on the grounds of the Council for Higher Education in Israel, Israel Academy of Sciences and Humanities, and Van Leer Jerusalem Institute. Ilse Rosenthal-Schneider (April 25, 1891 – February 6, 1990) was a German-Australian physicist and philosopher.  She is best known for her collaboration and correspondence with physicists Albert Einstein, Max von Laue, and Max Planck.  Rosenthal-Schneider earned a PhD in philosophy in 1920 at the University of Berlin, where she first met Albert Einstein.  After leaving Nazi Germany and emigrating to Australia in 1938, she became a tutor in the German department at the University of Sydney in 1945 and taught history and philosophy of science.  In the 1940s and 1950s, she exchanged a series of letters with Albert Einstein about philosophical aspects of physics, such as theory of relativity, fundamental constants and physical reality.  She remained in contact with Einstein through correspondence until the death of Einstein in 1955.
