his major subject and physics as a secondary subject. After Einstein arrived in
Prague, he took Nohel as his assistant upon Lampa's recommendation. There is
no record of Nohel's subsequent research. 'The many hours Einstein and my
father spent together in Einstein's study, his world view and character left a lasting
impression on my father. ... He was fond of Einstein's first wife and regretted
their separation.' Nohel got his PhD in 1912 or 1913. After Einstein's return to
Zurich, Nohel became a mathematics teacher at the Handelsakademie in Vienna,
a post he retained until the Anschluss of 1938. From 1938 to 1940 he was first a
teacher, then the principal of the Ghayes Gymnasium, the only remaining sec-
ondary school which Jewish children could attend in Vienna. In 1942 he was
interned in Theresienstadt (Teresin). He is mentioned in studies of life in the
camp as being active in educational work. After the rest of his family died in
Teresin, he voluntarily joined his sister upon deportation to the extermination
camps. Letters by Nohel to his son were deposited in the Yad va-Shem Memorial
Archives in Jerusalem. Einstein attempted to help Nohel but without success
[E12].
- Otto Stern, b. 1888, Sohrau, upper Silesia, (now Zory in Poland). PhD in
1912 in physical chemistry with Otto Sackur in Breslau. Stern came to Prague
with his own independent means to join Einstein and accompanied him to Zurich
when Einstein took up his position at the ETH. Einstein and Stern wrote a joint
paper dealing with an attempt (unsuccessful) to interpret anomalies in the specific
heats of gases at low temperatures [E13]. Helped by Einstein's advocacy, Stern
became Privatdozent in Zurich in 1913. The next year he moved to Frankfurt,
where the Stern-Gerlach experiments were performed in 1920-2. His discovery
of the anomalous magnetic moment of the proton was made in Hamburg in 1933.
Stern left Germany after the Nazis came to power, to become research professor
of physics at the Carnegie Institute of Technology (now Carnegie-Mellon Uni-
versity) in Pittsburgh. In 1944 he received the 1943 Nobel prize in physics 'for
his contributions to the molecular ray method and the discovery of the magnetic
moment of the proton.' After his retirement in 1946, he divided his time between
Berkeley and Zurich. When Jost and I visited him in Berkeley in the early 1960s,
he told us with tears in his eyes of the beautiful days with Einstein in Prague.*
d. 1969, Berkeley.
- Marcel Grossmann. b. 1878, Budapest. Fellow student of Einstein at the
ETH, 1896-1900. PhD in 1902 with Fiedler in Zurich. Grossmann and his
father were instrumental in getting Einstein appointed to the patent office in Bern.
In 1905 Einstein dedicated his PhD thesis to the younger Grossmann. The Ein-
stein-Grossmann collaboration is discussed at length in Chapter 12. d. 1936,
Zurich. Einstein remembered Grossmann with gratitude in his last autobiograph-
ical sketch [E14].**
