Walter Isaacson - Einstein - His Life and Universe

Einstein declined all official invitations from the Bermuda gentry and socialized instead with a German cook he met at a restaurant, who invited him to come sailing on his little boat. They were away for seven hours, and Elsa feared that Nazi agents may have nabbed her husband. But she found him at the cook’s home, where he had gone to enjoy a dinner of German dishes. 37

That summer, a house down the block from the one they were renting in Princeton went on sale. A modest white clapboard structure that peeked through a little front yard onto one of the town’s pleasant tree-lined arteries, 112 Mercer Street was destined to become a world-famous landmark not because of its grandeur but because it so perfectly suited and symbolized the man who lived there. Like the public persona that he adopted in later life, the house was unassuming, sweet, charming, and unpretentious. It sat there right on a main street, highly visible yet slightly cloaked behind a veranda.

Its modest living room was a bit overwhelmed by Elsa’s heavy German furniture, which had somehow caught up with them after all their wanderings. Helen Dukas commandeered the small library on the first floor as a workroom in which she dealt with Einstein’s correspondence and took charge of the only telephone in the house (Princeton 1606 was the unlisted number).

Elsa oversaw the construction of a second-floor office for Einstein. They removed part of the back wall and installed a picture window that looked out on the long and lush backyard garden. Bookcases on both sides went up to the ceiling. A large wooden table, cluttered with papers and pipes and pencils, sat in the center with a view out of the window, and there was an easy chair where Einstein would sit for hours scribbling on a pad of paper in his lap.

The usual pictures of Faraday and Maxwell were tacked on the walls. There was also, of course, one of Newton, although after a while it fell off its hook. To that mix was added a fourth: Mahatma Gandhi, Einstein’s new hero now that his passions were as much political as they were scientific. As a small joke, the only award displayed was a framed certificate of Einstein’s membership in the Bern Scientific Society.

Besides his menagerie of women, the household was joined, over the years, by various pets. There was a parrot named Bibo, who required an unjustifiable amount of medical care; a cat named Tiger; and a white terrier named Chico that had belonged to the Bucky family. Chico was an occasional problem. “The dog is very smart,” Einstein explained. “He feels sorry for me because I receive so much mail. That’s why he tries to bite the mailman.” 38

“The professor does not drive,” Elsa often said. “It’s too complicated for him.” Instead, he loved to walk, or, more precisely, shuffle, up Mercer Street each morning to his office at the Institute. People often snapped their heads when he passed, but the sight of him walking lost in thought was soon one of the well-known attractions of the town.

On his walk back home at midday, he would often be joined by three or four professors or students. Einstein would usually walk calmly and quietly, as if in a reverie, while they pranced around him, waved their arms, and tried to make their points. When they got to the house, the others would peel off, but Einstein sometimes just stood there thinking. Every now and then, unwittingly, he even started drifting back to the Institute. Dukas, always watching from her window, would come outside, take his arm, and lead him inside for his macaroni lunch. Then he would nap, dictate some answers to his mail, and pad up to his study for another hour or two of rumination about potential unified field theories. 39

Occasionally, he would take rambling walks on his own, which could be dicey. One day someone called the Institute and asked to speak to a particular dean. When his secretary said that the dean wasn’t available, the caller hesitantly asked for Einstein’s home address. That was not possible to give out, he was informed. The caller’s voice then dropped to a whisper. “Please don’t tell anybody,” he said, “but I am Dr. Einstein, I’m on my way home, and I’ve forgotten where my house is.” 40

This incident was recounted by the son of the dean, but like many of the tales about Einstein’s distracted behavior it may have been exaggerated. The absentminded professor image fit him so nicely and naturally that it became reinforcing. It was a role that Einstein was happy to play in public and that his neighbors relished recounting. And like most assumed roles, there was a core of truth to it.

At one dinner where Einstein was being honored, for example, he got so distracted that he pulled out his notepad and began scribbling equations. When he was introduced, the crowd burst into a standing ovation, but he was still lost in thought. Dukas caught his attention and told him to get up. He did, but noticing the crowd standing and applauding, he assumed it was for someone else and heartily joined in. Dukas had to come over and inform him that the ovation was for him. 41

In addition to the tales of the dreamy Einstein, another common theme was that of the kindly Einstein helping a child, usually a little girl, with her homework. The most famous of these involved an 8-year-old neighbor on Mercer Street, Adelaide Delong, who rang his bell and asked for help with a math problem. She carried a plate of homemade fudge as a bribe. “Come in,” he said. “I’m sure we can solve it.” He helped explain the math to her, but made her do her own homework. In return for the fudge, he gave her a cookie.

After that the girl kept reappearing. When her parents found out, they apologized profusely. Einstein waved them off. “That’s quite unnecessary,” he said. “I’m learning just as much from your child as she is learning from me.” He loved to tell, with a twinkle in his eye, the tale of her visits. “She was a very naughty girl,” he would laugh. “Do you know she tried to bribe me with candy?”

A friend of Adelaide’s recalled going with her and another girl on one of these visits to Mercer Street. When they got up to his study, Einstein offered them lunch, and they accepted. “So he moved a whole bunch of papers from the table, opened four cans of beans with a can opener, and heated them on a Sterno stove one by one, stuck a spoon in each and that was our lunch,” she recalled. “He didn’t give us anything to drink.” 42

Later, Einstein famously told another girl who complained about her problems with math, “Do not worry about your difficulties in mathematics; I can assure you that mine are even greater.” But lest it be thought he helped only girls, he hosted a group of senior boys from the Princeton Country Day School who were baffled by a problem on their math final exam. 43

He also helped a 15-year-old boy at Princeton High School, Henry Rosso, who was doing poorly in a journalism course. His teacher had offered an A to anyone who scored an interview with Einstein, so Rosso showed up at Mercer Street but was rebuffed at the door. As he was slinking away, the milkman gave him a tip: Einstein could be found walking a certain route every morning at 9:30. So Rosso snuck out of school one day, positioned himself accordingly, and was able to accost Einstein as he wandered by.

Rosso was so flummoxed that he did not know what to ask, which may have been why he was doing poorly in the course. Einstein took pity on him and suggested questions. No personal topics, he insisted. Ask about math instead. Rosso was smart enough to follow his advice. “I discovered that nature was constructed in a wonderful way, and our task is to find out the mathematical structure of the nature itself,” Einstein explained of his own education at age 15. “It is a kind of faith that helped me through my whole life.”
