Question: Who was the famous physicist in the memoir Einstein Wrote Back, who was born in Vienna in 1869?

Einstein Wrote Back is a memoir by Canadian physicist John Moffat which documents his encounters with various other famous physicists, including Niels Bohr, Albert Einstein, Erwin Schrödinger, Fred Hoyle, Wolfgang Pauli, Paul Dirac, Abdus Salam, and J. Robert Oppenheimer, as well as his work at Imperial College London, Princeton University, CERN, and the University of Toronto. <SEP> Erika Mitterer (1906–2001) was an Austrian writer.  When she was 18, in 1924, she began writing poems to Rainer Maria Rilke, who wrote back with approximately fifty poems of his own, and called her verse a "Herzlandschaft" (landscape of the heart).  She wrote about 117 poems to him in all.  This was the only time Rilke had a productive poetic collaboration throughout all his work.  She also visited Rilke.  When she was 24 her first volume of poems was published; it was well-received, and Stefan Zweig called her "a great poet".  During the time of Nazi Germany she wrote for the periodical "Das innere Reich", and also published the novel "The Prince of Darkness".  In 1950 her "Correspondence in Verse" with Rilke was published, and received much praise.  In 1992 a documentary about her, titled "Ericka Mitterer, Das Videoportrait: Dank des Lebens" was made. <SEP> Goldschmiedt was born in Triest, Austria-Hungary.  He started studying economics at the business school in Frankfurt am Main, but then started attending science lectures in other educational institutions.  In 1869, he went back to Vienna, where part of his family lived, and studied chemistry at the University of Vienna.  There he attended lectures of Josef Redtenbacher and Franz Cölestin Schneider – the most prominent chemists of the time in Vienna.  In 1871, he moved to the University of Heidelberg, Germany.  There he received his PhD for work with Robert Wilhelm Bunsen and his assistant Blum in the field of inorganic analytical chemistry of minerals.  For a postdoctoral position, he joined the laboratory of Adolf von Baeyer at the University of Straßburg.  Goldschmiedt worked in the field of organic chemistry for two years, but he also studied mineralogy and crystallography with Paul Heinrich von Groth.  During that time, Emil Fischer and Franz S. Exner also worked with Baeyer in Straßburg.  For Goldschmiedt, the time in Straßburg ended abruptly because he joined the group of Schneiders at the University of Vienna.  After his habilitation in 1875, he was sent as official observer to the world fair in Philadelphia in 1876.  After visiting California, he went back to Vienna and married in 1886.  It took until 1890 for him to become assistant professor at University of Vienna, but only one year later he became full professor.  In 1891, Goldschmiedt moved to the German Charles-Ferdinand University in Prague and worked there for 20 years.  In the meantime, he received the Lieben Prize in 1892 and became a member of the Vorstand of Deutschen Chemischen Gesellschaft in 1900 and 1901.  In 1911, Goldschmiedt succeeded Zdenko Hans Skraup at the University of Vienna and was mostly involved in administrative tasks, such as supervising the construction of the laboratory building and reorganization of the institute.  Starting from 1914, his health deteriorated slowly but steadily, resulting in his eventual death on August 6, 1915. <SEP>  Pauli's middle name was given in honor of his godfather, physicist Ernst Mach.  Pauli's paternal grandparents were from prominent Jewish families of Prague; his great-grandfather was the Jewish publisher Wolf Pascheles. Pauli was born in Vienna to a chemist Wolfgang Joseph Pauli ("né" Wolf Pascheles, 1869–1955) and his wife Bertha Camilla Schütz; his sister was Hertha Pauli, the writer and actress.  Pauli's father converted from Judaism to Roman Catholicism shortly before his marriage in 1899.  Pauli's mother, Bertha Schütz, was raised in her own mother's Roman Catholic religion; her father was Jewish writer Friedrich Schütz.  Pauli was raised as a Roman Catholic, although eventually he and his parents left the Church.  He is considered to have been a deist and a mystic.
