“My name is Bacon, Professor. Francis Bacon.”

Frank had arrived at the institute at the agreed-upon hour. He had put on one of his best suits, rat-gray, and a tie with a pattern that looked like little giraffes.

“Oh, yes, Bacon. Born January 22, 1561, at York House. Died 1626. A lunatic, unfortunately. But, oh, yes, what a fertile mind. Did you know I could recite the entire Novum Organum for you, line by line, right now if I wanted? But I suppose that would be rather boring for you. Anyway, I have another appointment that I don’t want to be too late for.”

Of all the men of modern science, nobody seemed able to warm up to the cunning, turbulent nature of numbers quite as John von Neumann had. As a young scholar at Princeton, where he spent a few months as a professor of mathematics, he had acquired a reputation for being one of the most intelligent men in the entire world—and, at the same time, one of the worst professors imaginable. His name in Germany was Johannes, a transliteration of the original Hungarian Janós, and so he had little apprehension about translating it into English in order to adapt to the more casual way of his adopted country. Born in Budapest in 1903, he became Johnny von Neumann in the United States, which made him an odd mix of Scotch whisky and Czech beer. He was now only thirty-seven, but his career as a child prodigy had catapulted him early on into the pantheon of contemporary mathematics. For the past few months, he was also the youngest member of the Institute for Advanced Study. Bacon had never taken any of his courses, but the Princeton campus was rife with tales of the professor’s many eccentricities, and Bacon was familiar with all of them. As he would soon hear for himself, Von Neumann had a peculiar accent that was not precisely the result of his Central European provenance—in fact, many people said he had simply invented it himself. He always wore the same uniform, a neat, coffee-colored suit that he never varied, not even during the summer or for excursions into the nearby countryside. In addition to his gift for rapid-fire mathematical calculations, he also had a photographic memory: After merely scanning a page of text or quickly reading through a novel he could recite it by heart, from start to finish without committing a single error. He had done this several times with A Tale of Two Cities.

Impatient by nature, Von Neumann despised his students; he abhorred their slow minds and the countless unnecessary repetitions he was often obliged to parcel out, like a country farmer feeding his chickens. Worst of all, however, were the expressions of shock and fear that registered upon his students’ faces whenever they attempted to decipher one of his elegant, eloquent equations. Nobody, but nobody, was able to understand his lectures, simply because of the absurd speed at which he gave them. By the time a student had begun to copy out some labyrinthine formula Von Neumann had quickly scratched out on the blackboard, the surprisingly nimble professor had already grabbed his eraser and leapt into the next problem, as if the blackboard were a giant Broadway billboard. During Von Neumann’s tenure at Princeton, only one graduate student had managed to finish his thesis under Von Neumann’s direction, and after that experience, the professor knew he would never again put himself through the tedium of rereading poorly written proofs and decoding someone else’s muddle of arithmetic nonsense. When Abraham Flexner invited Von Neumann to join the institute, he was quick to mention that Von Neumann would have no teaching obligations whatsoever, just like all the other professors there. The mathematician gladly accepted the offer; this way, he would be forever free from the bothersome plague of busybody coeds who couldn’t even tell Mozart from Beethoven.

“I have to go now. A meeting with the inner sanctum, if you know what I mean. Tea and cookies and all those illustrious names. Well, not quite as illustrious as yours, but prominent enough that I shouldn’t be late, you know?” He stopped for a second. He was stocky, even slightly chubby, with a greasy double chin hiding beneath his rounded beard. His accent was truly impossible to place. “What are we going to do with you, Bacon? I’m sorry to have kept you waiting, I didn’t expect … Well, you tell me what to do.” Bacon tried in vain to say something. The way Von Neumann carried on a conversation reminded him of the caterpillar’s erratic, long-winded pronouncements in Alice in Wonderland. “All right, all right, that’s a fine idea, Bacon. Listen, tomorrow I’m throwing a little party, you know. I try to do that every so often; this place can be so boring sometimes. I’m always telling my wife that we should open a bar here, like the kind in Budapest, but she never listens to me. All right, I have to go now. I’ll expect you then, at my house tomorrow. Five o’clock, before the other guests arrive … One of those receptions, you know? To keep us from dying of boredom. I suppose you’ve heard about them. All right, I have to go. I’m sorry. Five o’clock, then. Don’t forget.”

“But, Professor …” Bacon tried interrupting him.

“I told you already, we’ll discuss your problem later on. At length, I promise. Now, if you’ll be so kind …”

After several minutes battling with an obtuse secretary to obtain the professor’s home address, Bacon finally arrived at Von Neumann’s house, at 26 Westcott Road, punctual as always. A pair of waiters were busy unloading trays of sandwiches from a catering truck parked in front of the main door to the house, carrying them methodically to the kitchen, like a team of laborers preparing to feed an ant farm. Bacon would never have admitted it, but of course he had heard about Von Neumann’s receptions. His guest list was like a Who’s Who of the Princeton intellectual scene; even Einstein was rumored to have dropped in on occasion. During this particular time, an atmosphere of war hovered over everything—after all, in less than a year Pearl Harbor would be bombed. But here, people seemed intent upon acting as if the world were the same as ever. Or perhaps people simply wanted to enjoy the last moments of calm before the storm hit.

Bacon rang the doorbell and waited a few seconds, but nobody answered. Emboldened, he entered the house along with one of the waiters and began timidly whispering, “Professor? Professor Von Neumann?” in a voice so low that nobody would have heard, even if standing three feet away. After a few minutes, a maid finally noticed him and went upstairs to announce his arrival to Von Neumann. Then the professor appeared, half dressed, with his jacket on and a tie slung over his arm.

“Bacon!”

“Yes, Professor.”

“You, you again!” He sat down in one of the living room chairs and signaled for Bacon to do the same. He began buttoning his shirt with his little fingers, fat as grapes. “Your persistence doesn’t bother me at all, no, not at all, but have some manners. I’m about to throw a party, you know? Wouldn’t you agree that this isn’t exactly the best moment to have a discussion about physics?”

“But you asked me to come, Professor.”

“Nonsense, nonsense, Bacon.” Now he was struggling with his tie. “Well, now that you’re here, it wouldn’t be right for you to leave empty-handed, would it? Manners, my friend, that’s what’s wrong with the Americans. Now, that’s nothing personal, I assure you, but it is beginning to bother me.” Von Neumann studied him, like a pathologist performing an autopsy. “I suppose that I am to decide whether you will be accepted at the institute, is that correct? Your future, sitting here in my hands. It’s a terrible responsibility, my friend, just terrible. How should I know whether you’re a genius or a fool?”

“I sent you my CV, Professor.”

“You’re a physicist, is that right?”

“That’s correct, sir.”

“Have you ever heard of such foolishness?” Von Neumann muttered. “Just because I wrote that tiny little book on quantum theory, why should that mean I have to review the file of every silly fool who decides to take up physics, right? Don’t look at me like that, my friend, I’m not talking about you, of course not. Well, I’m afraid that those imbeciles have sent me nothing.” Von Neumann got up from his chair in search of a mushroom vol-au-vent. When he located the tray, he picked it up and took it with him; he offered one to Bacon, who declined. “Can you believe it? Nothing. And the worst of all is that I bet it’s time for me to present my evaluation of you to the committee, Bacon. What can I do about it?”

“I don’t know, Professor.”

“I’ve got it!” he shouted, excited by his sudden revelation. “You are aware, are you not, that we are about to enter a war?”

Bacon didn’t seem to understand Von Neumann’s quick change of subject.

“Yes,” he said, just to say something.

“Mark my words, Bacon, we are going to war with Adolf and the Japs.”

“So many people oppose the idea of a war—”

“Are you afraid, is that what you’re trying to say? That you don’t want to save the world from the clutches of that monster?”

Bacon didn’t understand exactly where Von Neumann was headed; it almost seemed as though he was making fun of him, and so Bacon just tried to keep his answers noncommittal.

“Tell me, Bacon, what is a war?”

“I don’t know, a confrontation between two or more enemies?”

“But what else than that?” Von Neumann was getting agitated. “Why do they fight, Bacon, why?”

“Because they have contradictory interests,” Bacon spat out.

“For God’s sake, no; it’s precisely the opposite!”

“Because they have common interests?”

“Of course! They have the same objective, the same goal, but it is only available to one of them. That is why they go to war.”

Bacon was confused. Von Neumann, meanwhile, was trying to calm himself down with more mushroom sandwiches.

“Let me give you a simple example. Let’s take the Nazis and the British: What is their common objective? The same pie, Bacon: the Europe pie. Ever since Hitler took control of Germany in 1933, all he’s done is ask for pieces. First he wanted Austria, then Czechoslovakia, then Poland, Belgium, Holland, France, Norway. Now he wants the whole pie. At first, the British tolerated his expansion, like they did at that abominable conference in Munich, but then they realized that Germany had too much. You see?”

“I follow you, Professor. War is like a game.”

“Have you read my little article on the topic, the one published in 1928?” Von Neumann inquired, narrowing his eyes.

“‘On the Theory of Games of Strategy,’” replied Bacon. “I’ve heard about it, but I haven’t read it yet.”

“Right,” the professor mused. “All right. Suppose, then, that the war between Churchill and Hitler is a game. I will add one other condition—something that in the real case isn’t necessarily true at all, but in any event—the players that intervene in the game do so rationally.”

“I think I understand,” ventured Bacon. “They will do whatever it takes to obtain the result they desire: victory.”

“Very good.” Von Neumann finally smiled. “I’m working on a theory right now together with my friend, the economist Oskar Morgenstein. The theory states that all rational games must possess a mathematic solution.”

“A strategy.”

“You’ve got it, Bacon. The best strategy for any game—or war—is the one that leads to the best possible result,” Von Neumann cleared his throat with a swig of whisky. “Now, to my understanding, all games fall into one of two categories: zero-sum games and everything else. A game can only be considered zero-sum if the competitors are fighting over a finite, fixed object and if one person necessarily loses what the other one wins. If I only have one pie, each slice that I obtain represents a loss for my rival.”

“And in the non-zero-sum games, the advantages earned by one player don’t necessarily represent a loss for the other,” Bacon pronounced, satisfied.

“Right. Therefore, our war between the Nazis and the British …”

“… is a zero-sum game.”

“Correct. Let’s use it as a working hypothesis. What is the current status of the war? Hitler controls half of Europe. England barely puts up a fight. The Russians are holding out, waiting to see what happens, chained to their nonaggression pact with the Germans. If this is what things look like, Bacon, you tell me: What will be Hitler’s next move?” Von Neumann asked excitedly, his chest heaving up and down like a water pump.

It was a tough question, and Bacon knew there was a catch to it. His response shouldn’t reflect his intuition, he reasoned, but rather the mathematic expectations of his interrogator.

“Hitler is going to want another piece of that pie.”

“That’s exactly what I was hoping to hear!” Von Neumann exclaimed. “We’ve said that to Roosevelt over and over again. Now: Which piece, specifically?”

There were two possibilities. Bacon didn’t even flinch.

“I think Hitler’s going to start with Russia.”

“Why?”

“Because it’s the weakest of all his potential enemies, and he can’t allow Stalin to continue building his war chest for much longer.”

“Perfect, Bacon. Now comes the hard part.” Von Neumann was enjoying the young man’s astonishment. “Let’s take a look at our position on this issue, that of the United States of America. Right now we’re not involved, so we can be more objective. Let’s try to decide, rationally, what our course of action should be.”

Bacon and Von Neumann sat talking for over half an hour. In the meantime, the maid busied herself placing the plates and tablecloths in their proper places in the dining room, next to the drawing room. After a while, Klara, the professor’s wife—his second wife, actually—called out to Von Neumann from the staircase, chastising him for being late for his own party. Von Neumann waved his hand dismissively and signaled to his companion to stay where he was. Although he felt a bit silly, Bacon was enjoying the conversation; its dry humor and fast-paced exchanges reminded him of those chess games with his father so many years before. Beneath the apparent simplicity of this intellectual challenge, Bacon had the feeling that he was actually waging a most unusual battle against the professor. This was the kind of conversation he could imagine taking place between two spies from enemy countries, or two lovers unsure of one another’s affections. Each move was an attempt to get ahead of the next one, and so on and so on, and both men had to perform two tasks at once: They each had to carefully guard their own strategies, and at the same time figure out the other’s plan of attack. The conversation itself was a kind of game.

“My theory is the following,” said Von Neumann, as he took a sheet of paper from the coffee table and began outlining a neat, precise diagram. “The game we are playing with the Germans is not zero-sum because it involves the division of an even larger pie—the world—and there is a wide range of values ascribed to the different pie pieces that each side wants to keep for itself. This means that there are two strategies at play here, and four possible outcomes. The United States can decide to enter the war or not. The Axis countries can decide to attack us or not. What, then, are the four scenarios?”

Bacon responded with confidence:

“First, we attack them; second, they attack us by surprise; third, both sides attack simultaneously; fourth, things stay the way they are.”

“Now let’s consider the outcomes of each case. If we declare war, we have the potential advantage of surprising them, but many American lives would no doubt be lost in the process. If, on the other hand, they attack us first, they will possess that surprise margin but then they will be forced to wage a war on two fronts (provided that we are correct in assuming that they will attack the Reds at any time). Now, if we follow the third scenario and attack simultaneously, and go through all the obligatory declarations of war, etc., etc., both sides will have forfeited the surprise element, and both will suffer similar human losses. Now, if we opt for the last scenario, in which both sides leave things as they are, the likely outcome is that Hitler will take control of Europe and we will take North America, but in the long run, a conflict between the two sides will still be inevitable.”

“I like your analysis, Professor.”

“Thank you, Bacon. Now I’d like you to assign values to each of the possible outcomes, for our side and for theirs.”

“All right,” said Bacon, and he began to write on the piece of paper:

1. The United States and the Axis attack simultaneously: USA, 1; Axis, 1.

2. The United States launches a surprise attack against the Axis: USA, 3; Axis, 0.

3. The United States waits, and the Axis launches a surprise attack: USA, 0; Axis, 3.

4. The situation remains the same as it has been until now: USA, 2; Axis, 2.

Then Bacon drew the following diagram:

“The question is,” said Von Neumann, more excited than ever, “what should we do?”

Bacon contemplated the diagram as if it were a Renaissance painting. He found its simplicity as beautiful as Von Neumann did. It was a work of art.

“The worst-case scenario would be for us to wait and then get attacked by surprise. We would get a zero, and Adolf would come out with three. The problem is that we don’t know what that monster has planned. From that angle, I think the only rational solution is to attack first. If we can surprise the Nazis, then we earn a lovely three. If we simply engage in a simultaneous war, at least we’d get a one and not the zero that we’d deserve for being overly indulgent,” Bacon concluded, convinced. “That’s the answer. This way, at least, the outcome will depend on us.”

Von Neumann seemed even more satisfied than his student. Not only had Bacon proven his grit, but he and Von Neumann agreed about what decision President Roosevelt should make regarding the war. Ever since the discovery of uranium fission in 1939, Von Neumann had been one of the staunchest advocates for the establishment of a large-scale nuclear research program in the United States. An atomic bomb, if such a thing were possible, would not only take the Germans and the Japanese by surprise, but it could also end the war once and for all. Unfortunately, however, his message of warning had not seemed to have much effect on President Roosevelt.

“I think I shall have no other choice than to tolerate your tedious presence in the corridors of Fuld Hall,” Von Neumann announced, slowly rising from his chair. “But don’t go thinking this is paradise, Bacon. I am going to make you work like a mule until you end up despising every last equation I give you to solve. Be at my office next Monday.”

Von Neumann walked toward the staircase. The irritated voice of Klara Dan once again came bounding down from the second floor. Before retiring to his upstairs quarters, Von Neumann turned to Bacon one last time.

“If you don’t have anything better to do, you can stay for the party.”

In December of 1941, John von Neumann’s prediction came true, and the United States of America had no other choice but to enter the war. President Roosevelt had decided to remain neutral until the last possible moment, and the Japanese executed the best possible strategy: the surprise attack. The American public was shocked and outraged. Citizens from every walk of American life were angered and horrified.
