Einstein (7 page)

Einstein’s discomfort spiraled toward depression, perhaps even close to a nervous breakdown, when his father’s business suffered a sudden reversal of fortune. The collapse was a precipitous one. During most of Einstein’s school years, the Einstein brothers’ company had been a success. In 1885, it had two hundred employees and provided the first electrical lights for Munich’s Oktoberfest. Over the next few years, it won the contract to wire the community of Schwabing, a Munich suburb of ten thousand people, using gas motors to drive twin dynamos that the Einsteins had designed. Jakob Einstein received six patents for improvements in arc lamps, automatic circuit breakers, and electric meters. The company was poised to rival Siemens and other power companies then flourishing. To raise capital, the brothers mortgaged their homes, borrowed more than 60,000 marks at 10 percent interest, and went deeply in debt.

But in 1894, when Einstein was 15, the company went bust after it lost competitions to light the central part of Munich and other locations.
His parents and sister, along with Uncle Jakob, moved to northern Italy—first Milan and then the nearby town of Pavia—where the company’s Italian partners thought there would be more fertile territory for a smaller firm. Their elegant home was torn down by a developer to build an apartment block. Einstein was left behind in Munich, at the house of a distant relative, to finish his final three years of school.

It is not quite clear whether Einstein, in that sad autumn of 1894, was actually forced to leave the Luitpold Gymnasium or was merely politely encouraged to leave. Years later, he recalled that the teacher who had declared that his “presence spoils the respect of the class for me” had gone on to “express the wish that I leave the school.” An early book by a member of his family said that it was his own decision. “Albert increasingly resolved not to remain in Munich, and he worked out a plan.”

That plan involved getting a letter from the family doctor, Max Talmud’s older brother, who certified that he was suffering from nervous exhaustion. He used this to justify leaving the school at Christmas vacation in 1894 and not returning. Instead, he took a train across the Alps to Italy and informed his “alarmed” parents that he was never going back to Germany. Instead, he promised, he would study on his own and attempt to gain admission to a technical college in Zurich the following autumn.

There was perhaps one other factor in his decision to leave Germany. Had he remained there until he was 17, just over a year away, he would have been required to join the army, a prospect that his sister said “he contemplated with dread.” So, in addition to announcing that he would not go back to Munich, he would soon ask for his father’s help in renouncing his German citizenship.

Einstein spent the spring and summer of 1895 living with his parents in their Pavia apartment and helping at the family firm. In the process, he was able to get a good feel for the workings of magnets, coils, and generated electricity. Einstein’s work impressed his family. On one occasion, Uncle Jakob was having problems with some calculations
for a new machine, so Einstein went to work on it. “After my assistant engineer and I had been racking our brain for days, that young sprig had got the whole thing in just fifteen minutes,” Jakob reported to a friend. “You will hear of him yet.”

With his love of the sublime solitude found in the mountains, Einstein hiked for days in the Alps and Apennines, including an excursion from Pavia to Genoa to see his mother’s brother Julius Koch. Wherever he traveled in northern Italy, he was delighted by the non-Germanic grace and “delicacy” of the people. Their “naturalness” was a contrast to the “spiritually broken and mechanically obedient automatons” of Germany, his sister recalled.

Einstein had promised his family that he would study on his own to get into the local technical college, the Zurich Polytechnic.

So he bought all three volumes of Jules Violle’s advanced physics text and copiously noted his ideas in the margins. His work habits showed his ability to concentrate, his sister recalled. “Even in a large, quite noisy group, he could withdraw to the sofa, take pen and paper in hand, set the inkstand precariously on the armrest, and lose himself so completely in a problem that the conversation of many voices stimulated rather than disturbed him.”

That summer, at age 16, he wrote his first essay on theoretical physics, which he titled “On the Investigation of the State of the Ether in a Magnetic Field.” The topic was important, for the notion of the ether would play a critical role in Einstein’s career. At the time, scientists conceived of light simply as a wave, and so they assumed that the universe must contain an all-pervasive yet unseen substance that was doing the rippling and thus propagating the waves, just as water was the medium rippling up and down and thus propagating the waves in an ocean. They dubbed this the ether, and Einstein (at least for the time being) went along with the assumption. As he put it in his essay, “An electric current sets the surrounding ether in a kind of momentary motion.”

The fourteen-paragraph handwritten paper echoed Violle’s textbook as well as some of the reports in the popular science magazines about Heinrich Hertz’s recent discoveries about electromagnetic waves. In it, Einstein made suggestions for experiments that could explain “the magnetic field formed around an electric current.” This would be interesting, he argued, “because the exploration of the elastic state of the ether in this case would permit us a look into the enigmatic nature of electric current.”

The high school dropout freely admitted that he was merely making a few suggestions without knowing where they might lead. “As I was completely lacking in materials that would have enabled me to delve into the subject more deeply than by merely meditating about it, I beg you not to interpret this circumstance as a mark of superficiality,” he wrote.

He sent the paper to his uncle Caesar Koch, a merchant in Belgium, who was one of his favorite relatives and occasionally a financial patron. “It is rather naïve and imperfect, as might be expected from such a young fellow like myself,” Einstein confessed with a pretense of humility. He added that his goal was to enroll the following fall at the Zurich Polytechnic, but he was concerned that he was younger than the age requirement. “I should be at least two years older.”
⁵⁴

To help him get around the age requirement, a family friend wrote to the director of the Polytechnic, asking for an exception. The tone of the letter can be gleaned from the director’s response, which expressed skepticism about admitting this “so-called ‘child prodigy.’ ” Nevertheless, Einstein was granted permission to take the entrance exam, and he boarded the train for Zurich in October 1895 “with a sense of well-founded diffidence.”

Not surprisingly, he easily passed the section of the exam in math and science. But he failed to pass the general section, which included sections on literature, French, zoology, botany, and politics. The Polytechnic’s head physics professor, Heinrich Weber, suggested that Einstein stay in Zurich and audit his classes. Instead, Einstein decided, on the advice of the college’s director, to spend a year preparing
at the cantonal school in the village of Aarau, twenty-five miles to the west.
⁵⁵

It was a perfect school for Einstein. The teaching was based on the philosophy of a Swiss educational reformer of the early nineteenth century, Johann Heinrich Pestalozzi, who believed in encouraging students to visualize images. He also thought it important to nurture the “inner dignity” and individuality of each child. Students should be allowed to reach their own conclusions, Pestalozzi preached, by using a series of steps that began with hands-on observations and then proceeded to intuitions, conceptual thinking, and visual imagery.
⁵⁶
It was even possible to learn—and truly understand—the laws of math and physics that way. Rote drills, memorization, and force-fed facts were avoided.

Einstein loved Aarau. “Pupils were treated individually,” his sister recalled, “more emphasis was placed on independent thought than on punditry, and young people saw the teacher not as a figure of authority, but, alongside the student, a man of distinct personality.” It was the opposite of the German education that Einstein had hated. “When compared to six years’ schooling at a German authoritarian gymnasium,” Einstein later said, “it made me clearly realize how much superior an education based on free action and personal responsibility is to one relying on outward authority.”
⁵⁷

The visual understanding of concepts, as stressed by Pestalozzi and his followers in Aarau, became a significant aspect of Einstein’s genius. “Visual understanding is the essential and only true means of teaching how to judge things correctly,” Pestalozzi wrote, and “the learning of numbers and language must be definitely subordinated.”
⁵⁸

Not surprisingly, it was at this school that Einstein first engaged in the visualized thought experiment that would help make him the greatest scientific genius of his time: he tried to picture what it would be like to ride alongside a light beam. “In Aarau I made my first rather childish experiments in thinking that had a direct bearing on the Special Theory,” he later told a friend. “If a person could run after a light wave with the same speed as light, you would have a wave arrangement which could be completely independent of time. Of course, such a thing is impossible.”
⁵⁹

This type of visualized thought experiments—
Gedankenexperiment
—became a hallmark of Einstein’s career. Over the years, he would picture in his mind such things as lightning strikes and moving trains, accelerating elevators and falling painters, two-dimensional blind beetles crawling on curved branches, as well as a variety of contraptions designed to pinpoint, at least in theory, the location and velocity of speeding electrons.

While a student in Aarau, Einstein boarded with a wonderful family, the Wintelers, whose members would long remain entwined in his life. There was Jost Winteler, who taught history and Greek at the school; his wife, Rosa, soon known to Einstein as Mamerl, or Mama; and their seven children. Their daughter Marie would become Einstein’s first girlfriend. Another daughter, Anna, would marry Einstein’s best friend, Michele Besso. And their son Paul would marry Einstein’s beloved sister, Maja.

“Papa” Jost Winteler was a liberal who shared Einstein’s allergy to German militarism and to nationalism in general. His edgy honesty and political idealism helped to shape Einstein’s social philosophy. Like his mentor, Einstein would become a supporter of world federalism, internationalism, pacifism, and democratic socialism, with a strong devotion to individual liberty and freedom of expression.

More important, in the warm embrace of the Winteler family, Einstein became more secure and personable. Even though he still fancied himself a loner, the Wintelers helped him flower emotionally and open himself to intimacy. “He had a great sense of humor and at times could laugh heartily,” recalled daughter Anna. In the evenings he would sometimes study, “but more often he would sit with the family around the table.”

Einstein had developed into a head-turning teenager who possessed, in the words of one woman who knew him, “masculine good looks of the type that played havoc at the turn of the century.” He had wavy dark hair, expressive eyes, a high forehead, and jaunty demeanor. “The lower half of his face might have belonged to a sensualist who found plenty of reasons to love life.”

One of his schoolmates, Hans Byland, later wrote a striking description of “the impudent Swabian” who made such a lasting impression. “Sure of himself, his gray felt hat pushed back on his thick, black
hair, he strode energetically up and down in the rapid, I might say crazy, tempo of a restless spirit which carries a whole world in itself. Nothing escaped the sharp gaze of the large bright brown eyes. Whoever approached him was captivated by his superior personality. A mocking curl of his fleshy mouth with its protruding lower lip did not encourage Philistines to fraternize with him.”

Most notably, Byland added, young Einstein had a sassy, sometimes intimidating wit. “He confronted the world spirit as a laughing philosopher, and his witty sarcasm mercilessly castigated all vanity and artificiality.”

Einstein fell in love with Marie Winteler at the end of 1895, just a few months after he moved in with her parents. She had just completed teacher training college and was living at home while waiting to take a job in a nearby village. She was just turning 18, he was still 16. The romance thrilled both families. Albert and Marie sent New Year’s greetings to his mother; she replied warmly, “Your little letter, dear Miss Marie, brought me immense joy.”
⁶²

The following April, when he was back home in Pavia for spring break, Einstein wrote Marie his first known love letter:

Beloved sweetheart!

Many, many thanks sweetheart for your charming little letter, which made me endlessly happy. It was so wonderful to be able to press to one’s heart such a bit of paper which two so dear little eyes have lovingly beheld and on which the dainty little hands have charmingly glided back and forth. I was now made to realize, my little angel, the meaning of homesickness and pining. But love brings much happiness—much more so than pining brings pain . . .

My mother has also taken you to her heart, even though she does not know you; I only let her read two of your charming little letters. And she always laughs at me because I am no longer attracted to the girls who were supposed to have enchanted me so much in the past. You mean more to my soul than the whole world did before.

To which his mother penned a postscript: “Without having read this letter, I send you cordial greetings!”
