Einstein (56 page)

Unfortunately, Einstein made the mistake of ending the letter by pleading with Anna to help resolve the situation so that he could marry Elsa and end the shame that their relationship was causing her daughters. “Think of the two young girls, whose prospects of getting married are being hampered,” he said. “Do put in a good word for me sometime to Miza [Mari
] and make it clear to her how unkind it is to complicate the lives of others pointlessly.”

Anna shot back that Elsa was the one being selfish. “If Elsa had not wanted to make herself so vulnerable, she should not have run after you so conspicuously.”
³⁹

In truth, Anna was quite difficult, and she soon had a falling out with Mari
as well. “She tried to meddle in my affairs in a way that reveals potential human malice,” Mari
complained to Einstein. At the very least, this helped improve relations between the Einsteins. “I see from your letter that you also have had problems with Anna Besso,” he wrote Mari
just after they had agreed to the divorce terms. “She has written me such impertinent letters that I’ve put an end to further correspondence.”

It would be a few more months before the divorce decree could become final, but now that the negotiations were complete, everyone seemed relieved that there would be closure. Mari
’s health improved enough so that the children would remain with her,
⁴¹
and the letters
back and forth from Berlin and Zurich became friendlier. “A satisfactory relationship has formed between me and my wife through the correspondence about the divorce!” he told Zangger. “A funny opportunity indeed for reconciliation.”
⁴²

This détente meant that Einstein had an option for his summer vacation of 1918: visit his children in Zurich, or have a less stressful holiday with Elsa. He chose the latter, partly because his doctor recommended against the altitude, and for seven weeks he and Elsa stayed in the Baltic Sea resort of Aarenshoop. He brought along some light beach reading, Immanuel Kant’s
Prolegomena,
spent “countless hours pondering the quantum problem,” and gloried in relaxing and recovering from his stomach ailments. “No telephones, no responsibilities, absolute tranquility,” he wrote to a friend. “I am lying on the shore like a crocodile, allowing myself to be roasted by the sun, never see a newspaper, and do not give a hoot about the so-called world.”
⁴³

From this unlikely vacation, he sought to mollify Hans Albert, who had written to say he missed his father.“Write me please why you aren’t coming, at least,” he asked.
⁴⁴
Einstein’s explanation was sad and very defensive:

You can easily imagine why I could not come. This winter I was so sick that I had to lie in bed for over two months. Every meal must be cooked separately for me. I may not make any abrupt movements. So I’d have been allowed neither to go on a walk with you nor to eat at the hotel . . . Added to this is that I had quarreled with Anna Besso, and that I did not want to become a burden to Mr. Zangger again, and finally, that I doubted whether my coming mattered much to you.
⁴⁵

His son was understanding. He wrote him letters filled with news and ideas, including a description and sketch of an idea he had for a pendulum inside a monorail that would swing and break the electric circuit whenever the train tilted too much.

Einstein had rebuked Hans Albert, unfairly, for not finding some way to visit him in Germany during the vacation. That would have required Mari
to waive the provision in their separation agreement that barred such trips, and it would also have been sadly impractical. “My coming to Germany would be almost more impossible than your coming
here,” Hans Albert wrote, “because in the end I am the only one in the family who can shop for anything.”
⁴⁶

So Einstein, yearning to be nearer to his boys, found himself briefly tempted to move back to Zurich. During his Baltic vacation that summer of 1918, he considered a combined offer from the University of Zurich and his old Zurich Polytechnic. “You can design your position here exactly as you wish,” the physicist Edgar Meyer wrote. As Einstein jokingly noted to Besso, “How happy I would have been 18 years ago with a measly assistantship.”
⁴⁷

Einstein admitted that he was tormented by the decision. Zurich was his “true home,” and Switzerland was the only country for which he felt any affinity. Plus, he would be near his sons.

But there was one rub. If he moved close to his sons he would be moving close to their mother. Even for Einstein, who was good at shielding himself from personal emotions, it would be hard to set up household with Elsa in the same town as his first wife.“My major personal difficulties would persist if I pitched my tent in Zurich again,” he told Besso, “although it does seem tempting to be close to my children.”
⁴⁸

Elsa was also adamantly opposed to the prospect, even appalled. She begged Einstein to promise it would not happen. Einstein could be quite solicitous about Elsa’s desires, and so he backed away from a full-time move to Zurich.

Instead, he did something he usually avoided: he compromised. He retained his position in Berlin but agreed to be a guest lecturer in Zurich, making month-long visits there twice a year. That, he thought, could give him the best of both worlds.

In what seemed like an excess of Swiss caution, the Zurich authorities approved the lecture contract, which paid Einstein his expenses but no fee, “by way of experiment.” They were in fact wise; Einstein’s lectures were initially very popular, but eventually attendance dwindled and they would be canceled after two years.

Which would finish first, Einstein had wondered half-jokingly to Mari
, the world war or their divorce proceedings? As it turned out,
both came to a messy resolution at the end of 1918. As the German Reich was crumbling that November, a revolt by sailors in Kiel mushroomed into a general strike and popular uprising. “Class canceled because of Revolution,” Einstein noted in his lecture diary on November 9, the day that protestors occupied the Reichstag and the kaiser abdicated. Four days later, a worker-student revolutionary council took over the University of Berlin and jailed its deans and rector.

With the outbreak of war, Einstein had become, for the first time, an outspoken public figure, advocating internationalism, European federalism, and resistance to militarism. Now, the coming of the peace turned Einstein’s political thinking toward more domestic and social issues.

From his youth as an admirer of Jost Winteler and a friend of Friedrich Adler, Einstein had been attracted to the ideal of socialism as well as that of individual freedom. The revolution in Berlin—led by a collection of socialists, workers’ councils, communists, and others on the left—caused him to confront cases when these two ideals conflicted.

For the rest of his life Einstein would expound a democratic socialism that had a liberal, anti-authoritarian underpinning. He advocated equality, social justice, and the taming of capitalism. He was a fierce defender of the underdog. But to the extent that any revolutionaries edged over toward a Bolshevik desire to impose centralized control, or to the extent that a regime such as Russia’s struck him as authoritarian, Einstein’s instinctive love of individual liberty usually provoked a disdainful reaction.
