Walter Isaacson Great Innovators e-book boxed set

by Walter Isaacson

  At that point, it was Einstein’s turn to lose his composure. “I vehemently denied we had been living in sin,” he reported to Mari, “and scolded her roundly.”

  Just as he was about to storm out, a friend of his mother’s came in, “a small, vivacious lady, an old hen of the most pleasant variety.” They promptly segued into the requisite small talk: about the weather, the new guests at the spa, the ill-mannered children. Then they went off to eat and play music.

  Such periods of storm and calm alternated throughout the vacation. Every now and then, just when Einstein thought that the crisis had receded, his mother would revisit the topic.“Like you, she’s a book, but you ought to have a wife,” she scolded at one point. Another time she brought up the fact that Mari was 24 and he was then only 21. “By the time you’re 30, she’ll be an old witch.”

  Einstein’s father, still working back in Milan, weighed in with “a moralistic letter.” The thrust of his parents’ views—at least when applied to the situation of Mileva Mari rather than Marie Winteler—was that a wife was “a luxury” affordable only when a man was making a comfortable living. “I have a low opinion of that view of a relationship between a man and wife,” he told Mari,“because it makes the wife and the prostitute distinguishable only insofar as the former is able to secure a lifelong contract.”2

  Over the ensuing months, there would be times when it seemed as if his parents had decided to accept their relationship. “Mama is slowly resigning herself,” Einstein wrote Mari in August. Likewise in September: “They seem to have reconciled themselves to the inevitable. I think they will both come to like you very much once they get to know you.” And once again in October: “My parents have retreated, grudgingly and with hesitation, from the battle of Dollie—now that they have seen that they’ll lose it.”3

  But repeatedly, after each period of acceptance, their resistance would flare up anew, randomly leaping into a higher state of frenzy. “Mama often cries bitterly and I don’t have a single moment of peace,” he wrote at the end of August. “My parents weep for me almost as if I had died. Again and again they complain that I have brought misfortune upon myself by my devotion to you. They think you are not healthy.”4

  His parents’ dismay had little to do with the fact that Mari was not Jewish, for neither was Marie Winteler, nor that she was Serbian, although that certainly didn’t help her cause. Primarily, it seems, they considered her an unsuitable wife for many of the reasons that some of Einstein’s friends did: she was older, somewhat sickly, had a limp, was plain looking, and was an intense but not a star intellectual.

  All of this emotional pressure stoked Einstein’s rebellious instincts and his passion for his “wild street urchin,” as he called her. “Only now do I see how madly in love with you I am!”The relationship, as expressed in their letters, remained equal parts intellectual and emotional, but the emotional part was now filled with a fire unexpected from a self-proclaimed loner. “I just realized that I haven’t been able to kiss you for an entire month, and I long for you so terribly much,” he wrote at one point.

  During a quick trip to Zurich in August to check on his job prospects, he found himself walking around in a daze. “Without you, I lack self-confidence, pleasure in my work, pleasure in life—in short, without you my life is not life.” He even tried his hand at a poem for her, which began: “Oh my! That Johnnie boy! / So crazy with desire / While thinking of his Dollie / His pillow catches fire.”5

  Their passion, however, was an elevated one, at least in their minds. With the lonely elitism of young German coffeehouse denizens who have read the philosophy of Schopenhauer once too often, they un-abashedly articulated the mystical distinction between their own rarefied spirits and the baser instincts and urges of the masses. “In the case of my parents, as with most people, the senses exercise a direct control over the emotions,” he wrote her amid the family wars of August. “With us, thanks to the fortunate circumstances in which we live, the enjoyment of life is vastly broadened.”

  To his credit, Einstein reminded Mari (and himself) that “we mustn’t forget that many existences like my parents’ make our existence possible.” The simple and honest instincts of people like his parents had ensured the progress of civilization. “Thus I am trying to protect my parents without compromising anything that is important to me—and that means you, sweetheart!”

  In his attempt to please his mother, Einstein became a charming son at their grand hotel in Melchtal. He found the endless meals excessive and the “overdressed” patrons to be “indolent and pampered,” but he dutifully played his violin for his mother’s friends, made polite conversation, and feigned a cheerful mood. It worked. “My popularity among the guests here and my music successes act as a balm on my mother’s heart.”6

  As for his father, Einstein decided that the best way to assuage him, as well as to draw off some of the emotional charge generated by his relationship with Mari, was to visit him back in Milan, tour some of his new power plants, and learn about the family firm “so I can take Papa’s place in an emergency.” Hermann Einstein seemed so pleased that he promised to take his son to Venice after the inspection tour. “I’m leaving for Italy on Saturday to partake of the ‘holy sacraments’ administered by my father, but the valiant Swabian* is not afraid.”

  Einstein’s visit with his father went well, for the most part. A distant yet dutiful son, he had fretted mightily about each family financial crisis, perhaps even more than his father did. But business was good for the moment, and that lifted Hermann Einstein’s spirits. “My father is a completely different man now that he has no more financial worries,” Einstein wrote Mari. Only once did the “Dollie affair” intrude enough to make him consider cutting short his visit, but this threat so alarmed his father that Einstein stuck to the original plans. He seemed flattered that his father appreciated both his company and his willingness to pay attention to the family business.7

  Even though Einstein occasionally denigrated the idea of being an engineer, it was possible that he could have followed that course at the end of the summer of 1900—especially if, on their trip to Venice, his father had asked him to, or if fate intervened so that he was needed to take his father’s place. He was, after all, a low-ranked graduate of a teaching college without a teaching job, without any research accomplishments, and certainly without academic patrons.

  Had he made such a choice in 1900, Einstein would have likely become a good enough engineer, but probably not a great one. Over the ensuing years he would dabble with inventions as a hobby and come up with some good concepts for devices ranging from noiseless refrigerators to a machine that measured very low voltage electricity. But none resulted in a significant engineering breakthrough or marketplace success. Though he would have been a more brilliant engineer than his father or uncle, it is not clear that he would have been any more financially successful.

  Among the many surprising things about the life of Albert Einstein was the trouble he had getting an academic job. Indeed, it would be an astonishing nine years after his graduation from the Zurich Polytechnic in 1900—and four years after the miracle year in which he not only upended physics but also finally got a doctoral dissertation accepted—before he would be offered a job as a junior professor.

  The delay was not due to a lack of desire on his part. In the middle of August 1900, between his family vacation in Melchtal and his visit to his father in Milan, Einstein stopped back in Zurich to see about getting a post as an assistant to a professor at the Polytechnic. It was typical that each graduate would find, if he wanted, some such role, and Einstein was confident it would happen. In the meantime, he rejected a friend’s offer to help him get a job at an insurance company, dismissing it as “an eight hour day of mindless drudgery.” As he told Mari, “One must avoid stultifying affairs.”8

  The problem was that the two physics professors at the Polytechnic were acutely aware of his impudence but not of his genius. Getting a job with Professor Pernet, who
had reprimanded him, was not even a consideration. As for Professor Weber, he had developed such an allergy to Einstein that, when no other graduates of the physics and math department were available to become his assistant, he instead hired two students from the engineering division.

  That left math professor Adolf Hurwitz. When one of Hurwitz’s assistants got a job teaching at a high school, Einstein exulted to Mari: “This means I will become Hurwitz’s servant, God willing.” Unfortunately, he had skipped most of Hurwitz’s classes, a slight that apparently had not been forgotten.9

  By late September, Einstein was still staying with his parents in Milan and had not received an offer. “I plan on going to Zurich on October 1 to talk with Hurwitz personally about the position,” he said. “It’s certainly better than writing.”

  While there, he also planned to look for possible tutoring jobs that could tide them over while Mari prepared to retake her final exams. “No matter what happens, we’ll have the most wonderful life in the world. Pleasant work and being together—and what’s more, we now answer to no one, can stand on our own two feet, and enjoy our youth to the utmost. Who could have it any better? When we have scraped together enough money, we can buy bicycles and take a bike tour every couple of weeks.”10

  Einstein ended up deciding to write Hurwitz instead of visiting him, which was probably a mistake. His two letters do not stand as models for future generations seeking to learn how to write a job application. He readily conceded that he did not show up at Hurwitz’s calculus classes and was more interested in physics than math. “Since lack of time prevented me from taking part in the mathematics seminar,” he rather lamely said, “there is nothing in my favor except the fact that I attended most of the lectures offered.” Rather presumptuously, he said he was eager for an answer because “the granting of citizenship in Zurich, for which I have applied, has been made conditional upon my proving that I have a permanent job.”11

  Einstein’s impatience was matched by his confidence. “Hurwitz still hasn’t written me more,” he said only three days after sending his letter, “but I have hardly any doubt that I will get the position.” He did not. Indeed, he managed to become the only person graduating in his section of the Polytechnic who was not offered a job. “I was suddenly abandoned by everyone,” he later recalled.12

  By the end of October 1900 he and Mari were both back in Zurich, where he spent most of his days hanging out at her apartment, reading and writing. On his citizenship application that month, he wrote “none” on the question asking his religion, and for his occupation he wrote, “I am giving private lessons in mathematics until I get a permanent position.”

  Throughout that fall, he was able to find only eight sporadic tutoring jobs, and his relatives had ended their financial support. But Einstein put up an optimistic front. “We support ourselves by private lessons, if we can ever pick up some, which is still very doubtful,” he wrote a friend of Mari’s. “Isn’t this a journeyman’s or even a gypsy’s life? But I believe that we will remain cheerful in it as ever.”13 What kept him happy, in addition to Mari’s presence, were the theoretical papers he was writing on his own.

  Einstein’s First Published Paper

  The first of these papers was on a topic familiar to most school kids: the capillary effect that, among other things, causes water to cling to the side of a straw and curve upward. Although he later called this essay “worthless,” it is interesting from a biographical perspective. Not only is it Einstein’s first published paper, but it shows him heartily embracing an important premise—one not yet fully accepted—that would be at the core of much of his work over the next five years: that molecules (and their constituent atoms) actually exist, and that many natural phenomena can be explained by analyzing how these particles interact with one another.

  During his vacation in the summer of 1900, Einstein had been reading the work of Ludwig Boltzmann, who had developed a theory of gases based on the behavior of countless molecules bouncing around. “The Boltzmann is absolutely magnificent,” he enthused to Mari in September. “I am firmly convinced of the correctness of the principles of his theory, i.e., I am convinced that in the case of gases we are really dealing with discrete particles of definite finite size which move according to certain conditions.”14

  To understand capillarity, however, required looking at the forces acting between molecules in a liquid, not a gas. Such molecules attract one another, which accounts for the surface tension of a liquid, or the fact that drops hold together, as well as for the capillary effect. Einstein’s idea was that these forces might be analogous to Newton’s gravitational forces, in which two objects are attracted to each other in proportion to their mass and in inverse proportion to their distance from one another.

  Einstein looked at whether the capillary effect showed such a relationship to the atomic weight of various liquid substances. He was encouraged, so he decided to see if he could find some experimental data to test the theory further. “The results on capillarity I recently obtained in Zurich seem to be entirely new despite their simplicity,” he wrote Mari. “When we’re back in Zurich we’ll try to get some empirical data on this subject . . . If this yields a law of nature, we’ll send the results to the Annalen.”15

  He did end up sending the paper in December 1900 to the Annalen der Physik, Europe’s leading physics journal, which published it the following March. Written without the elegance or verve of his later papers, it conveyed what is at best a tenuous conclusion. “I started from the simple idea of attractive forces among the molecules, and I tested the consequences experimentally,” he wrote. “I took gravitational forces as an analogy.” At the end of the paper, he declares limply, “The question of whether and how our forces are related to gravitational forces must therefore be left completely open for the time being.”16

  The paper elicited no comments and contributed nothing to the history of physics. Its basic conjecture was wrong, as the distance dependence is not the same for differing pairs of molecules.17 But it did get him published for the first time. That meant that he now had a printed article to attach to the job-seeking letters with which he was beginning to spam professors all over Europe.

  In his letter to Mari, Einstein had used the term “we” when discussing plans to publish the paper. In two letters written the month after it appeared, Einstein referred to “our theory of molecular forces” and “our investigation.”Thus was launched a historical debate over how much credit Mari deserves for helping Einstein devise his theories.

  In this case, she mainly seemed to be involved in looking up some data for him to use. His letters conveyed his latest thoughts on molecular forces, but hers contained no substantive science. And in a letter to her best friend, Mari sounded as if she had settled into the role of supportive lover rather than scientific partner. “Albert has written a paper in physics that will probably be published very soon in the Annalen der Physik,” she wrote. “You can imagine how very proud I am of my darling. This is not just an everyday paper, but a very significant one. It deals with the theory of liquids.”18

  Jobless Anguish

  It had been almost four years since Einstein had renounced his German citizenship, and ever since then he had been stateless. Each month, he put aside some money toward the fee he would need to pay to become a Swiss citizen, a status he deeply desired. One reason was that he admired the Swiss system, its democracy, and its gentle respect for individuals and their privacy. “I like the Swiss because, by and large, they are more humane than the other people among whom I have lived,” he later said.19 There were also practical reasons; in order to work as a civil servant or a teacher in a state school, he would have to be a Swiss citizen.

  The Zurich authorities examined him rather thoroughly, and they even sent to Milan for a report on his parents. By February 1901, they were satisfied, and he was made a citizen. He would retain that designation his entire life, even as he accepted citizenships in Germany (again), Austria, and the United
States. Indeed, he was so eager to be a Swiss citizen that he put aside his antimilitary sentiments and presented himself, as required, for military service. He was rejected for having sweaty feet (“hyperidrosis ped”), flat feet (“pes planus”), and varicose veins (“varicosis”). The Swiss Army was, apparently, quite discriminating, and so his military service book was stamped “unfit.”20

  A few weeks after he got his citizenship, however, his parents insisted that he come back to Milan and live with them. They had decreed, at the end of 1900, that he could not stay in Zurich past Easter unless he got a job there. When Easter came, he was still unemployed.

  Mari, not unreasonably, assumed that his summons to Milan was due to his parents’ antipathy toward her. “What utterly depressed me was the fact that our separation had to come about in such an unnatural way, on account of slanders and intrigues,” she wrote her friend. With an absentmindedness he was later to make iconic, Einstein left behind in Zurich his nightshirt, toothbrush, comb, hairbrush (back then he used one), and other toiletries. “Send everything along to my sister,” he instructed Mari, “so she can bring them home with her.” Four days later, he added, “Hold on to my umbrella for the time being. We’ll figure out something to do with it later.”21

  Both in Zurich and then in Milan, Einstein churned out job-seeking letters, ever more pleading, to professors around Europe. They were accompanied by his paper on the capillary effect, which proved not particularly impressive; he rarely even received the courtesy of a response. “I will soon have graced every physicist from the North Sea to the southern tip of Italy with my offer,” he wrote Mari.22
