Although he had been labeled as Jewish, Haber did have to option of remaining in his office, because he
was a veteran of war. This option was at first considered a great deal by Haber, because if he remained in his
position, from there he could aid those younger Jewish scientists who now found themselves in a bad
predicament.
11
Haber‟s desire to remain at this position would quickly dissipate though; as several incidents
occurred that he would consider to be the final straw.
First, on April 15
th
, Haber‟s friend and colleague, James Franck resigned from his position at the
University of Göttingen. Franck had been in the same exact predicament as Haber, yet decided he did not want
to continue at his post. In a letter he quickly wrote to Haber, Franck tried to explain to Haber his reasons for
leaving, “I can‟t just get up in front of my students and act as though all this doesn‟t matter to me. And I also
can‟t gnaw on the bone that the government tosses to Jewish war veterans. I honor and understand the position of
those who want to hold out in their positions, but there also have to be people like me. So don‟t scold your James
Franck, who loves you.”

Having his friends around him resigning would have made him realize even more
deeply how the world around him was changing.
Then, like all other civil servants, Haber was forced to fill-out a questionnaire about his ancestry. The
paper asked for his race, which he answered as “non-Aryan,” and also for a list of all his parents and
grandparents. In this section, he simply wrote “My parents and grandparents and both women to whom I‟ve been
married as well as their ancestors were all non-Aryan as defined by the law.”

Haber was incensed that he, who
had been baptized at a young age and who had also always been a loyal and devoted patriot to his country,
should be targeted by the Nazis because of his ancestry. So then, on April 30, 1933, Fritz Haber issued his
resignation. He would remain at the institute for five more months, so that a replacement could be found, but
then he would leave. Not only did he want to leave his position at this point, but he also wanted to leave
Germany.
Fritz Haber now was looking for a position outside of Germany. 1933, while corresponding with an
English chemist, discussing a fellowship at a university there, Haber described the intense remorse that he felt,
being betrayed by his country the way he had been:
I have never in my life courted any honors, and I am deeply ashamed to write this. But perhaps
you will have some understanding for the feelings of an old man who was tied to his country for
- 56 -
his whole life, but who now has the feeling that he has lost his homeland – a homeland that his
ancestors and he served to the best of their ability.

In 1933, Haber travelled to England, France, and Holland, looking for a position. He did not find any at
this time, but he did strike-up a friendship with the Zionist leader Chaim Weizmann. The two had met several
years earlier in Paris, and Weizmann had thought that Haber “was lacking in a Jewish self-respect. He had
converted to Christianity and had pulled all his family with him along the road to apostasy.”
15
At their second
meeting, however, Weizmann described Haber as “broken, muddled, moving about in a mental and moral
vacuum.” He even stated that he “made a feeble attempt to comfort him, but the truth is that I could scarcely
look him in the eyes. I was ashamed for myself, ashamed for this cruel world, which allowed such things to
happen, and ashamed for the error in which he had lived and worked throughout his life.”

Haber remained in Berlin until August 3, when he headed to Paris to visit his son, Hermann. He would
never again set foot in his once beloved fatherland. It was while he was in Paris that Haber began corresponding
with Sir William Pope, who would eventually facilitate Haber being offered a position at a university in
England. About his decision to accept this position, he told his 13-year-old son Ludwig-Fritz:
I will in all probability move to England and live at the University of Cambridge. I would like
you to go to an English boarding school. It would then be possible for you to become an English
citizen, which is the best opportunity that you could be granted in life.... As for Eva, I don‟t
know if the most important thing for her is to live with her mother, or whether you feel it is most
important for the two of you to be together…. In any case, it will be necessary in the coming
years for both of you to learn to speak English and French as well as you now speak German.
For your future lives, this is absolutely necessary in these times.

Haber did not want his children to meet the same fate that he had met. They were, or course, of Jewish
decent and he did not them to be limited by all the new laws and delegations in Germany. Outside of his once
beloved homeland, only then would they find the freedom to do as they wish. This helped him to finally decide
that he must accept the position offered to him in Cambridge.
Before relocating to Cambridge, however, Haber travelled to several locations in Europe. It was in Brig,
Switzerland where he had a serious collapse cause by what he assumed was a stroke. Shortly after regaining
