hand, “became a convinced pacifist and internationalist and,
in diluted form, a socialist.”

In support of the war and opposing Allied accusations of German atrocities in Belgium, Haber, his friend
Richard Willstätter, and 91 others signed the “Manifesto of the 93”. The document denied that Germany had
committed atrocities and also asserted that Germany was blameless for starting the war; Germany‟s culture and
military tradition were emphasized as being “one and the same.”
8
Responding to this proclamation, Einstein co-
wrote the “Manifesto of the Europeans” with Georg Nicolai; this opposed the first manifesto. It was distributed
among the scientists in Berlin, but only two others, Wilhelm Forster and Otto Bück, signed.
9
Throughout much of the war, Haber continued to believe in “Germany‟s ultimate victory” while Einstein
believed that the war was “a kind of suicidal drama in Europe‟s history, an eruption of insanity.”
10
Additionally,
Einstein joined a peace group named the Federation of the Germans, founded in November 1914, which wanted
the war to end quickly and peacefully as well as to prevent future wars from occurring. While abroad, he often
made remarks expressing his disapproving and opposing thoughts on the war and since he was still a state
official in Prussia, these remarks “bordered on high treason.”
11
Surprisingly, despite Haber‟s fervent patriotism and Einstein‟s great pacifism, which Haber could have
considered a deal-breaker, so to speak, they remained friends; Haber did not permit the political actions of his
friend to alter his high estimation of Einstein both as person and also as a scientist. Einstein even tutored the then
thirteen-year-old Hermann Haber in mathematics during the beginning of 1915 because the child was “quite sick
and couldn‟t go to school.”
12
Haber also continued to rally for Einstein‟s cause at the Institute by helping to
found the Kaiser Wilhelm Society‟s Institute for Physics in the fall of 1917; he sat on its board of directors
together with Einstein.
13
By 1917, Haber had lost his faith that Germany would win the war. Einstein described his thoughts on
the horrific war by stating that, “Our entire much-praised technological progress, and civilization generally could
be compared to an ax in the hand of a pathological criminal.”
14
Thus, with the armistice of November 11, in
1918, Einstein was overjoyed that the war was to end. Haber, however, had poured his soul into the German war
effort and now had to deal with the great loss and well as any repercussions his actions may have caused
amongst his friends.
In January 1918, Einstein was trying to help one of his fellow physicists travel to neutral Holland, and
- 38 -
Haber took the liberty of taking a request for this action to the very top of the military ranks. Einstein apparently
rebuked Haber‟s attempt to help and Haber tried to explain his actions to his friend in a letter
15
:
Nothing was further removed from my mind… than [to feel] pleasure at your unfamiliarity
with military custom… It is not only in the field of mathematical physics that life depends on
the knowledge of and acceptance of certain formal connections and not only in the field in
which you work miracles is it usually impossible to achieve success without the formal laws.
For myself I merely ask that you believe that I am pleased and happy to be useful to you, that I
have too much respect for your person and achievement to ever make fun about something you
do and that I personally am extremely fond of you [ich Sie persönlich lieb habe].
16
Haber clearly did not intend to embarrass his friend, but it does seem that he was very proud that he was
able to take the request to the highest military authorities. He reveled in his ranking and the power it allotted
him, yet with the end of the war he was forced to integrate himself back into civilian life. This was only made
harder when he was listed among the war criminals to be tried for their actions during the war. He was forced to
flee to Switzerland but was eventually able to return to Germany when the charges were dropped.
During these difficult times for Haber, Einstein was celebrating the changes occurring in Germany, for
he had detested the old regime. His theory of relativity was also gaining more acclaim, being called “one of the
greatest- perhaps the greatest of achievements in the history of human thought.”
17
Einstein was joining Haber
among the elite of German scientists, as well as German society. Yet his actions promoting Zionism sometimes
caused his friend to question whether or not Einstein was patriotic and supportive of Germany at all.
Einstein planned to travel to the United States in the spring of 1921 with Chaim Weizmann, a leading
Zionist and a distinguished chemist at Manchester University. The pair planned to raise funds for a Hebrew
University in Jerusalem. This trip reflected Einstein‟s deep connection with his Jewish heritage and brought to
the light the great divide between himself and Haber over this issue. Einstein had, in fact, even refused an
important invitation, in May 1918, from the Imperial Academy of Sciences to travel to St. Petersburg stating that
“I find it repugnant to travel without necessity to a country in which my tribesmen are so brutally persecuted.”
18
Having much earlier converted from Judaism, Haber commented little on his friend‟s outspoken ethnic views,
yet he did not wish for his friend to travel to the United States in 1921. He did not believe that Einstein should
