By April 1901, Einstein was reduced to buying a pile of postcards with postage-paid reply attachments in the forlorn hope that he would, at least, get an answer. In the two cases where these postcard pleas have survived, they have become, rather amusingly, prized collectors’ items. One of them, to a Dutch professor, is now on display in the Leiden Museum for the History of Science. In both cases, the return-reply attachment was not used; Einstein did not even get the courtesy of a rejection. “I leave no stone unturned and do not give up my sense of humor,” he wrote his friend Marcel Grossmann. “God created the donkey and gave him a thick skin.”23
Among the great scientists Einstein wrote was Wilhelm Ostwald, professor of chemistry in Leipzig, whose contributions to the theory of dilution were to earn him a Nobel Prize. “Your work on general chemistry inspired me to write the enclosed article,” Einstein said. Then flattery turned to plaintiveness as he asked “whether you might have use for a mathematical physicist.” Einstein concluded by pleading: “I am without money, and only a position of this kind would enable me to continue my studies.” He got no answer. Einstein wrote again two weeks later using the pretext “I am not sure whether I included my address” in the earlier letter. “Your judgment of my paper matters very much to me.” There was still no answer.24
Einstein’s father, with whom he was living in Milan, quietly shared his son’s anguish and tried, in a painfully sweet manner, to help. When no answer came after the second letter to Ostwald, Hermann Einstein took it upon himself, without his son’s knowledge, to make an unusual and awkward effort, suffused with heart-wrenching emotion, to prevail upon Ostwald himself:
Please forgive a father who is so bold as to turn to you, esteemed Herr Professor, in the interest of his son. Albert is 22 years old, he studied at the Zurich Polytechnic for four years, and he passed his exam with flying colors last summer. Since then he has been trying unsuccessfully to get a position as a teaching assistant, which would enable him to continue his education in physics. All those in a position to judge praise his talents; I can assure you that he is extraordinarily studious and diligent and clings with great love to his science. He therefore feels profoundly unhappy about his current lack of a job, and he becomes more and more convinced that he has gone off the tracks with his career. In addition, he is oppressed by the thought that he is a burden on us, people of modest means. Since it is you whom my son seems to admire and esteem more than any other scholar in physics, it is you to whom I have taken the liberty of turning with the humble request to read his paper and to write to him, if possible, a few words of encouragement, so that he might recover his joy in living and working. If, in addition, you could secure him an assistant’s position, my gratitude would know no bounds. I beg you to forgive me for my impudence in writing you, and my son does not know anything about my unusual step.25
Ostwald still did not answer. However, in one of history’s nice ironies, he would become, nine years later, the first person to nominate Einstein for the Nobel Prize.
Einstein was convinced that his nemesis at the Zurich Polytechnic, physics professor Heinrich Weber, was behind the difficulties. Having hired two engineers rather than Einstein as his own assistant, he was apparently now giving him unfavorable references. After applying for a job with Göttingen professor Eduard Riecke, Einstein despaired to Mari: “I have more or less given up the position as lost. I cannot believe that Weber would let such a good opportunity pass without doing some mischief.” Mari advised him to write Weber, confronting him directly, and Einstein reported back that he had. “He should at least know that he cannot do these things behind my back. I wrote to him that I know that my appointment now depends on his report alone.”
It didn’t work. Einstein again got turned down. “Riecke’s rejection hasn’t surprised me,” he wrote Mari. “I’m completely convinced that Weber is to blame.” He became so discouraged that, at least for the moment, he felt it futile to continue his search. “Under these circumstances it no longer makes sense to write further to professors, since, should things get far enough along, it is certain they would all enquire with Weber, and he would again give a poor reference.” To Grossmann he lamented, “I could have found a job long ago had it not been for Weber’s underhandedness.”26
To what extent did anti-Semitism play a role? Einstein came to believe that it was a factor, which led him to seek work in Italy, where he felt it was not so pronounced. “One of the main obstacles in getting a position is absent here, namely anti-Semitism, which in German-speaking countries is as unpleasant as it is a hindrance,” he wrote Mari. She, in turn, lamented to her friend about her lover’s difficulties. “You know my sweetheart has a sharp tongue and moreover he is a Jew.”27
In his effort to find work in Italy, Einstein enlisted one of the friends he had made while studying in Zurich, an engineer named Michele Angelo Besso. Like Einstein, Besso was from a middle-class Jewish family that had wandered around Europe and eventually settled in Italy. He was six years older than Einstein, and by the time they met he had already graduated from the Polytechnic and was working for an engineering firm. He and Einstein forged a close friendship that would last for the rest of their lives (they died within weeks of each other in 1955).
Over the years, Besso and Einstein would share both the most intimate personal confidences and the loftiest scientific notions. As Einstein wrote in one of the 229 extant letters they exchanged, “Nobody else is so close to me, nobody knows me so well, nobody is so kindly disposed to me as you are.”28
Besso had a delightful intellect, but he lacked focus, drive, and diligence. Like Einstein, he had once been asked to leave high school because of his insubordinate attitude (he sent a petition complaining about a math teacher). Einstein called Besso “an awful weakling . . . who cannot rouse himself to any action in life or scientific creation, but who has an extraordinarily fine mind whose working, though disorderly, I watch with great delight.”
Einstein had introduced Besso to Anna Winteler of Aarau, Marie’s sister, whom he ended up marrying. By 1901 he had moved to Trieste with her. When Einstein caught up with him, he found Besso as smart, as funny, and as maddeningly unfocused as ever. He had recently been asked by his boss to inspect a power station, and he decided to leave the night before to make sure that he arrived on time. But he missed his train, then failed to get there the next day, and finally arrived on the third day—“but to his horror realizes that he has forgotten what he’s supposed to do.” So he sent a postcard back to the office asking them to resend his instructions. It was the boss’s assessment that Besso was “completely useless and almost unbalanced.”
Einstein’s assessment of Besso was more loving. “Michele is an awful schlemiel,” he reported to Mari, using the Yiddish word for a hapless bumbler. One evening, Besso and Einstein spent almost four hours talking about science, including the properties of the mysterious ether and “the definition of absolute rest.”These ideas would burst into bloom four years later, in the relativity theory that he would devise with Besso as his sounding board. “He’s interested in our research,” Einstein wrote Mari, “though he often misses the big picture by worrying about petty considerations.”
Besso had some connections that could, Einstein hoped, be useful. His uncle was a mathematics professor at the polytechnic in Milan, and Einstein’s plan was to have Besso provide an introduction: “I’ll grab him by the collar and drag him to his uncle, where I’ll do the talking myself.” Besso was able to persuade his uncle to write letters on Einstein’s behalf, but nothing came of the effort. Instead, Einstein spent most of 1901 juggling temporary teaching assignments and some tutoring.29
It was Einstein’s other close friend from Zurich, his classmate and math note-taker Marcel Grossmann, who ended up finally getting Einstein a job, though not one that would have been expected. Just when Einstein was beginning to despair, Grossmann wrote that there was likely to be an opening for an examiner at the Swiss Patent Office, located in Bern. Grossmann’s father knew the di
rector and was willing to recommend Einstein.
“I was deeply moved by your devotion and compassion, which did not let you forget your luckless friend,” Einstein replied. “I would be delighted to get such a nice job and that I would spare no effort to live up to your recommendation.” To Mari he exulted: “Just think what a wonderful job this would be for me! I’ll be mad with joy if something should come of that.”
It would take months, he knew, before the patent-office job would materialize, assuming that it ever did. So he accepted a temporary post at a technical school in Winterthur for two months, filling in for a teacher on military leave. The hours would be long and, worse yet, he would have to teach descriptive geometry, neither then nor later his strongest field. “But the valiant Swabian is not afraid,” he proclaimed, repeating one of his favorite poetic phrases.30
In the meantime, he and Mari would have the chance to take a romantic vacation together, one that would have fateful consequences.
Lake Como, May 1901
“You absolutely must come see me in Como, you little witch,” Einstein wrote Mari at the end of April 1901. “You’ll see for yourself how bright and cheerful I’ve become and how all my brow-knitting is gone.”
The family disputes and frustrating job search had caused him to be snappish, but he promised that was now over. “It was only out of nervousness that I was mean to you,” he apologized. To make it up to her, he proposed that they should have a romantic and sensuous tryst in one of the world’s most romantic and sensuous places: Lake Como, the grandest of the jewel-like Alpine finger lakes high on the border of Italy and Switzerland, where in early May the lush foliage bursts forth under majestic snow-capped peaks.
“Bring my blue dressing-gown so we can wrap ourselves up in it,” he said. “I promise you an outing the likes of which you’ve never seen.”31
Mari quickly accepted, but then changed her mind; she had received a letter from her family in Novi Sad “that robs me of all desire, not only for having fun, but for life itself.” He should make the trip on his own, she sulked.“It seems I can have nothing without being punished.” But the next day she changed her mind again. “I wrote you a little card yesterday while in the worst of moods because of a letter I received. But when I read your letter today I became a bit more cheerful, since I see how much you love me, so I think we’ll take that trip after all.”32
And thus it was that early on the morning of Sunday, May 5, 1901, Albert Einstein was waiting for Mileva Mari at the train station in the village of Como, Italy, “with open arms and a pounding heart.” They spent the day there, admiring its gothic cathedral and walled old town, then took one of the stately white steamers that hop from village to village along the banks of the lake.
They stopped to visit Villa Carlotta, the most luscious of all the famous mansions that dot the shore, with its frescoed ceilings, a version of Antonio Canova’s erotic sculpture Cupid and Psyche, and five hundred species of plants. Mari later wrote a friend how much she admired “the splendid garden, which I preserved in my heart, the more so because we were not allowed to swipe a single flower.”
After spending the night in an inn, they decided to hike through the mountain pass to Switzerland, but found it still covered with up to twenty feet of snow. So they hired a small sleigh,“the kind they use that has just enough room for two people in love with each other, and a coachman stands on a little plank in the rear and prattles all the time and calls you ‘signora,’ ” Mari wrote. “Could you think of anything more beautiful?”
The snow was falling merrily, as far as the eye could see, “so that this cold, white infinity gave me the shivers and I held my sweetheart firmly in my arms under the coats and shawls covering us.” On the way down, they stomped and kicked at the snow to produce little avalanches, “so as to properly scare the world below.”33
A few days later, Einstein recalled “how beautiful it was the last time you let me press your dear little person against me in that most natural way.”34 And in that most natural way, Mileva Mari became pregnant with Albert Einstein’s child.
After returning to Winterthur, where he was a substitute teacher, Einstein wrote Mari a letter that made reference to her pregnancy. Oddly—or perhaps not oddly at all—he began by delving into matters scientific rather than personal.“I just read a wonderful paper by Lenard on the generation of cathode rays by ultraviolet light,” he started. “Under the influence of this beautiful piece I am filled with such happiness and joy that I must share some of it with you.” Einstein would soon revolutionize science by building on Lenard’s paper to produce a theory of light quanta that explained this photoelectric effect. Even so, it is rather surprising, or at least amusing, that when he rhapsodized about sharing “happiness and joy” with his newly pregnant lover, he was referring to a paper on beams of electrons.
Only after this scientific exultation came a brief reference to their expected child, whom Einstein referred to as a boy: “How are you darling? How’s the boy?” He went on to display an odd notion of what parenting would be like: “Can you imagine how pleasant it will be when we’re able to work again, completely undisturbed, and with no one around to tell us what to do!”
Most of all, he tried to be reassuring. He would find a job, he pledged, even if it meant going into the insurance business. They would create a comfortable home together. “Be happy and don’t fret, darling. I won’t leave you and will bring everything to a happy conclusion. You just have to be patient! You will see that my arms are not so bad to rest in, even if things are beginning a little awkwardly.”35
Mari was preparing to retake her graduation exams, and she was hoping to go on to get a doctorate and become a physicist. Both she and her parents had invested enormous amounts, emotionally and financially, in that goal over the years. She could have, if she had wished, terminated her pregnancy. Zurich was then a center of a burgeoning birth control industry, which included a mail-order abortion drug firm based there.
Instead, she decided that she wanted to have Einstein’s child—even though he was not yet ready or willing to marry her. Having a child out of wedlock was rebellious, given their upbringings, but not uncommon. The official statistics for Zurich in 1901 show that 12 percent of births were illegitimate. Residents who were Austro-Hungarian, moreover, were much more likely to get pregnant while unmarried. In southern Hungary, 33 percent of births were illegitimate. Serbs had the highest rate of illegitimate births, Jews by far the lowest.36
The decision caused Einstein to focus on the future. “I will look for a position immediately, no matter how humble it is,” he told her. “My scientific goals and my personal vanity will not prevent me from accepting even the most subordinate position.” He decided to call Besso’s father as well as the director of the local insurance company, and he promised to marry her as soon as he settled into a job. “Then no one can cast a stone on your dear little head.”
The pregnancy could also resolve, or so he hoped, the issues they faced with their families. “When your parents and mine are presented with a fait accompli, they’ll just have to reconcile themselves to it as best they can.”37
Mari, bedridden in Zurich with pregnancy sickness, was thrilled. “So, sweetheart, you want to look for a job immediately? And have me move in with you!” It was a vague proposal, but she immediately pronounced herself “happy” to agree. “Of course it mustn’t involve accepting a really bad position, darling,” she added. “That would make me feel terrible.” At her sister’s suggestion she tried to convince Einstein to visit her parents in Serbia for the summer vacation. “It would make me so happy,” she begged. “And when my parents see the two of us physically in front of them, all their doubts will evaporate.”38
But Einstein, to her dismay, decided to spend the summer vacation again with his mother and sister in the Alps. As a result, he was not there to help and encourage her at the end of July 1901 when she re-took her exams. Perhaps as a consequence of her pregnancy and personal situation, Mi
leva ended up failing for the second time, once again getting a 4.0 out of 6 and once again being the only one in her group not to pass.
Thus it was that Mileva Mari found herself resigned to giving up her dream of being a scientific scholar. She visited her home in Serbia—alone—and told her parents about her academic failure and her pregnancy. Before leaving, she asked Einstein to send her father a letter describing their plans and, presumably, pledging to marry her. “Will you send me the letter so I can see what you’ve written?” she asked. “By and by I’ll give him the necessary information, the unpleasant news as well.”39
Disputes with Drude and Others
Einstein’s impudence and contempt for convention, traits that were abetted by Mari, were evident in his science as well as in his personal life in 1901. That year, the unemployed enthusiast engaged in a series of tangles with academic authorities.
The squabbles show that Einstein had no qualms about challenging those in power. In fact, it seemed to infuse him with glee. As he proclaimed to Jost Winteler in the midst of his disputes that year, “Blind respect for authority is the greatest enemy of truth.” It would prove a worthy credo, one suitable for being carved on his coat of arms if he had ever wanted such a thing.
His struggles that year also reveal something more subtle about Einstein’s scientific thinking: he had an urge—indeed, a compulsion—to unify concepts from different branches of physics. “It is a glorious feeling to discover the unity of a set of phenomena that seem at first to be completely separate,” he wrote to his friend Grossmann as he embarked that spring on an attempt to tie his work on capillarity to Boltzmann’s theory of gases. That sentence, more than any other, sums up the faith that underlay Einstein’s scientific mission, from his first paper until his last scribbled field equations, guiding him with the same sure sense that was displayed by the needle of his childhood compass.40
