Einstein: His Life and Universe

Not surprisingly, Einstein found solace in his work. He admitted to Hans Albert that focusing was difficult, but the attempt provided him the means to escape the painfully personal. “As long as I am able to work, I must not and will not complain, because work is the only thing that gives substance to life.”⁴⁸

When he came to the office, he was “ashen with grief,” his collaborator Banesh Hoffmann noted, but he insisted on delving into their work each day. He needed it more than ever, he said. “At first his attempts to concentrate were pitiful,” Hoffmann recalled. “But he had known sorrow before and had learned that work was a precious antidote.”⁴⁹ Together they worked that month on two major papers: one that explored how the bending of light by the gravitational fields of galaxies could create “cosmic lenses” that would magnify distant stars, and another that explored the existence of gravitational waves.⁵⁰

Max Born learned of Elsa’s death in a letter from Einstein in which it was mentioned almost as an afterthought in explaining why he had become less social. “I live like a bear in my cave, and really feel more at home than ever before in my eventful life,” he told his old friend. “This bearlike quality has been further enhanced by the death of my woman comrade, who was better with other people than I am.” Born later marveled at “the incidental way” in which Einstein broke the news of his wife’s death. “For all his kindness, sociability and love of humanity,” commented Born, “he was nevertheless totally detached from his environment and the human beings in it.”⁵¹

That was not entirely true. For a self-styled bear in a cave, Einstein attracted a clan wherever he went. Whether it was walking home from the Institute, puttering around 112 Mercer Street, or sharing summer cottages and Manhattan weekends with the Watters or Bucky families, Einstein was rarely alone, except when he trundled up to his study. He could keep an ironic detachment and retreat into his own reveries, but he was a true loner only in his own mind.

After Elsa died, he still lived with Helen Dukas and his stepdaughter Margot, and soon thereafter his sister moved in. Maja had been living near Florence with her husband, Paul Winteler. But when Mussolini enacted laws in 1938 that withdrew resident status from all foreign Jews, Maja moved to Princeton on her own. Einstein, who loved her dearly and liked her immensely, was thrilled.

Einstein also encouraged Hans Albert, now 33, to come to America, at least for a visit. Their relationship had been rocky, but Einstein had come to admire the diligence of his son’s engineering work, especially regarding the flow of rivers, a topic he had once studied himself.⁵² He had also changed his mind and encouraged his son to have children, and he was now happy to have two young grandsons.

In October 1937, Hans Albert arrived for a three-month stay. Einstein met him at the pier, where they posed for photographs, and Hans Albert playfully lit a long Dutch pipe he had brought his father. “My father would like me to come here with my family,” he said. “You know his wife died recently and he is all alone now.”⁵³

During the visit, young and eager Peter Bucky offered to drive Hans Albert across America so that he could visit universities and seek positions as an engineering professor. The trip, which covered ten thousand miles, took them to Salt Lake City, Los Angeles, Iowa City, Knoxville, Vicksburg, Cleveland, Chicago, Detroit, and Indianapolis.⁵⁴ Einstein reported to Mileva Mari how much he had enjoyed being with their son. “He has such a great personality,” he wrote. “It is unfortunate that he has this wife, but what can you do if he’s happy?”⁵⁵

Einstein had written Frieda a few months earlier and suggested that she not accompany her husband on the trip.⁵⁶ But with his affection for Hans Albert fully restored, Einstein urged both of them to return together the following year, with their two children, and stay in America. They did. Hans Albert found a job studying soil conservation at a U.S. Department of Agriculture extension station in Clemson, South Carolina, where he became an authority on alluvial transport by rivers. Displaying his father’s taste, he built a simple wooden house, reminiscent of that in Caputh, in nearby Greenville, where he applied for American citizenship in December 1938.⁵⁷

While his father was becoming more connected to his Jewish heritage, Hans Albert became, under the influence of his wife, a Christian Scientist. The rejection of medical care, as sometimes entailed by that faith, had tragic results. A few months after their arrival, their 6-year-old son, Klaus, contracted diphtheria and died. He was buried at a tiny new cemetery in Greenville. “The deepest sorrow loving parents can experience has come upon you,” Einstein wrote in a condolence note. His relationship with his son became increasingly secure and even, at times, affectionate.

During the five years that Hans Albert lived in South Carolina, before moving to Caltech and then Berkeley, Einstein would occasionally take the train down to visit. There they would discuss engineering puzzles that reminded Einstein of his days at the Swiss patent office. In the afternoon, he would sometimes wander the roads and forests, often in dreamy thought, spawning colorful anecdotes from astonished locals who helped him find his way home.⁵⁸

Because he was a mental patient, Eduard was not allowed to immigrate to America. As his illness progressed, his face became bloated, his speech slow. Mari increasingly had trouble allowing him back home, so his stays in the institution became more prolonged. Her sister Zorka, who had come to help care for them, descended into her own hell. After their mother died, she became an alcoholic, accidentally burned all the family money, which had been hidden in an old stove, and died a recluse in 1938 on a straw-covered floor surrounded only by her cats.⁵⁹ Mari lived on, through it all, in increasing despair.

Prewar Politics

In retrospect, the rise of the Nazis created a fundamental moral challenge for America. At the time, however, this was not so clear. That was especially true in Princeton, which was a conservative town, and at its university, which harbored a surprising number of students who shared the amorphous anti-Semitic attitude found among some in their social class. A survey of incoming freshmen in 1938 produced a result that is now astonishing, and should have been back then as well: Adolf Hitler polled highest as the “greatest living person.” Albert Einstein was second.⁶⁰

“Why do They Hate the Jews?” Einstein wrote in an article for the popular weekly Collier’s that year. He used the article not just to explore anti-Semitism but also to explain how the social creed inbred in most Jews, which he personally tried to live by, was part of a long and proud tradition. “The bond that has united the Jews for thousands of years and that unites them today is, above all, the democratic ideal of social justice coupled with the ideal of mutual aid and tolerance among all men.”⁶¹

His kinship with his fellow Jews, and his horror at the plight that was befalling them, plunged him into the effort for refugee relief. It was both a public and a private endeavor. He gave dozens of speeches for the cause, was feted at even more dinners, and even gave occasional violin recitals for the American Friends Service Committee or the United Jewish Appeal. One gimmick that organizers used was to have people write their checks to Einstein himself. He would then endorse them to the charity. The donor would thus have as a keepsake a cancelled check with Einstein’s autograph.⁶² He also quietly backed scores of individuals who needed financial guarantees in order to emigrate, especially as the United States made it harder to get visas.
