Walter Isaacson - Einstein - His Life and Universe

Elsa and her daughters came out that afternoon for a small, private celebration. She was dismayed to find him in his oldest suit, which she had hidden. “How did you manage to find it?” she asked.

“Ah,” he replied, “I know all about those hiding places.” 1

The New York Times, as intrepid as ever, was the only paper that managed to track him down. A family member later recalled that Einstein’s angry look drove the reporter away. That was not true. The reporter was smart and Einstein, despite his feigned fury, was as accommodating as usual. “Einstein Is Found Hiding on His Birthday” was the paper’s headline. He showed the reporter a microscope he had been given as a gift, and the paper reported that he was like a “delighted boy” with a new toy. 2

From around the world came other gifts and greetings. The ones that moved him the most were from ordinary people. A seamstress had sent him a poem, and an unemployed man had saved a few coins to get him a small packet of tobacco. The latter gift brought tears to his eyes and was the first for which he wrote a thank-you letter. 3

Another birthday gift caused more problems. The city of Berlin, at the suggestion of the ever-meddling Dr. Plesch, decided to honor its most famous citizen by giving him lifelong rights to live in a country house that was part of a large lakeside estate that the city had acquired. There he would be able to escape, sail his wooden boat, and scribble his equations in serenity.

It was a generous and gracious gesture. It was also a welcome one. Einstein loved sailing and solitude and simplicity, but he owned no weekend retreat and had to store his sailboat with friends. He was thrilled to accept.

The house, in a classical style, was nestled in a park near the village of Cladow on a lake of the Havel River. Pictures of it appeared in the papers, and a relative called it “the ideal residence for a person of creative intellect and a man fond of sailing.” But when Elsa went to inspect it, she found still living there the aristocratic couple who sold the estate to the city. They claimed that they had retained the right to live on the property. A study of the documents proved them right, and they could not be evicted.

So the city decided to give the Einsteins another part of the estate on which they could build their own home. But that, too, violated the city’s purchase agreement. Pressure and publicity only hardened the resolve of the original family to block the Einsteins from building on the land, and it became an embarrassing front-page fiasco, especially after a third suggested alternative also proved unsuitable.

Finally it was decided that the Einsteins should simply find their own piece of land, and the city would buy it. So Einstein picked out a parcel, owned by some friends, farther out of town near a village just south of Potsdam called Caputh. It was in a sylvan spot between the Havel and a dense forest, and Einstein loved it. The mayor accordingly asked the assembly of city deputies to approve spending 20,000 marks to buy the property as the fiftieth birthday gift to Einstein.

A young architect drew up plans, and Einstein bought a small garden plot nearby. Then politics intervened. In the assembly, the right-wing German Nationalists objected, delayed the vote, and insisted that the proposal be put on a future agenda for a full debate. It became clear that Einstein personally would become the focus of that debate.

So he wrote a letter, tinged with amusement, declining the gift. “Life is very short,” he told the mayor, “while the authorities work slowly. My birthday is already past, and I decline the gift.” The headline the next day in the Berliner Tageblatt newspaper read, “Public Disgrace Complete / Einstein Declines.” 4

By this point, the Einsteins had fallen in love with the plot of land in Caputh, negotiated its purchase, and had a design for a house to build upon it. So they went ahead and bought it with their own money. “We have spent most of our savings,” Elsa complained, “but we have our land.”

The house they built was simple, with polished wood panels inside and unvarnished planks showing to the outside. Through a large picture window was a serene view of the Havel. Marcel Breuer, the famed Bauhaus furniture designer, had offered to do the interior design, but Einstein was a man of conservative tastes. “I am not going to sit on furniture that continually reminds me of a machine shop or a hospital operating room,” he said. Some leftover heavy pieces from the Berlin apartment were used instead.

Einstein’s room on the ground floor had a spartan wooden table, a bed, and a small portrait of Isaac Newton. Elsa’s room was also downstairs, with a shared bathroom between them. Upstairs were small rooms with sleeping niches for her two daughters and their maid. “I like living in the new little wooden house enormously, even though I am broke as a result,” he wrote his sister shortly after moving in. “The sailboat, the sweeping view, the solitary fall walks, the relative quiet—it is a paradise.” 5

There he sailed the new twenty-three-foot boat his friends had given him for his birthday, the Tümmler, or Dolphin, which was built fat and solid to his specifications. He liked to go out on the water alone, even though he didn’t swim. “He was absurdly happy as soon as he reached the water,” recalled a visitor. 6For hours he would let the boat drift and glide aimlessly as he gently toyed with the rudder. “His scientific thinking, which never leaves him even on the water, takes on the nature of a daydream,” according to one relative. “Theoretical thinking is rich in imagination.” 7

Companions

Throughout Einstein’s life, his relationships with women seemed subject to untamed forces. His magnetic appeal and soulful manner repeatedly attracted women. And even though he usually shielded himself from entangling commitments, he occasionally found himself caught in the swirl of a passionate attraction, just as he had been with Mileva Mari and even Elsa.

In 1923, after marrying Elsa, he had fallen in love with his secretary, Betty Neumann. Their romance was serious and passionate, according to newly revealed letters. That fall, while on a visit to Leiden, he wrote to suggest that he might take a job in New York, and she could come as his secretary. She would live there with him and Elsa, he fantasized. “I will convince my wife to allow this,” he said. “We could live together forever. We could get a large house outside New York.”

She replied by ridiculing both him and the idea, which prompted him to concede how much of a “crazy ass” he had been. “You have more respect for the difficulties of triangular geometry than I, old mathematicus, have.” 8

He finally terminated their romance with the lament that he “must seek in the stars” the true love that was denied to him on earth. “Dear Betty, laugh at me, the old donkey, and find somebody who is ten years younger than me and loves you just as much as I do.” 9

But the relationship lingered. The following summer, Einstein went to see his sons in southern Germany, and from there he wrote to his wife that he could not visit her and her daughters, who were at a resort nearby, because that would be “too much of a good thing.” At the same time, he was writing Betty Neumann saying that he was going secretly to Berlin, but she should not tell anyone because if Elsa found out she “will fly back.” 10

After he built the house in Caputh, a succession of women friends visited him there, with Elsa’s grudging acquiescence. Toni Mendel, a wealthy widow with an estate on the Wannsee, sometimes came sailing with him in Caputh, or he would pilot his boat up to her villa and stay late into the night playing the piano. They even went to the theater together in Berlin occasionally. Once when she picked Einstein up in her chauffeured limousine, Elsa got into a furious fight with him and would not give him any pocket money.
