eactions, suggested that a new type of bomb could result, and urged the president to set up formal contact with physicists working on this topic.<br />
Szilárd then prepared and sent back to Einstein a 45-line version and a 25-line one, both dated August 2, 1939, “and left it up to Einstein to choose<br />
which he liked best.” Einstein signed them both in a small scrawl, rather than with the flourish he sometimes used. 8<br />
The longer version, which is the one that eventually reached Roosevelt, read in part:<br />
Sir:<br />
Some recent work by E. Fermi and L. Szilárd, which has been communicated to me in a manuscript, leads me to expect that the element<br />
uranium may be turned into a new and important source of energy in the immediate future. Certain aspects of this situation which has arisen<br />
seem to call for watchfulness and, if necessary, quick action on the part of the Administration. I believe therefore that it is my duty to bring to<br />
your attention the following facts and recommendations:<br />
. . . It may become possible to set up a nuclear chain reaction in a large mass of uranium, by which vast amounts of power and large<br />
quantities of new radium-like elements would be generated. Now it appears almost certain that this could be achieved in the immediate future.<br />
This new phenomena would also lead to the construction of bombs, and it is conceivable—though much less certain—that extremely<br />
powerful bombs of a new type may thus be constructed. A single bomb of this type, carried by boat and exploded in a port, might very well<br />
destroy the whole port together with some of the surrounding territory . . .<br />
In view of this situation you may think it desirable to have some permanent contact maintained between the administration and the group of<br />
physicists working on chain reactions in America.<br />
It ended with a warning that German scientists might be pursuing a bomb. Once the letter had been written and signed, they still had to figure out<br />
who could best get it into the hands of President Roosevelt. Einstein was unsure about Sachs. They considered, instead, financier Bernard Baruch<br />
and MIT President Karl Compton.<br />
More amazingly, when Szilárd sent back the typed version of the letter, he suggested that they use as their intermediary Charles Lindbergh,<br />
whose solo transatlantic flight twelve years earlier had made him a celebrity. All three of the refugee Jews were apparently unaware that the aviator<br />
had been spending time in Germany, was decorated the year before by the Nazi Hermann Göring with that nation’s medal of honor, and was<br />
becoming an isolationist and Roosevelt antagonist.<br />
Einstein had briefly met Lindbergh a few years earlier in New York, so he wrote a note of introduction, which he included when he returned the<br />
signed letters to Szilárd. “I would like to ask you to do me a favor of receiving my friend Dr. Szilárd and think very carefully about what he will tell<br />
you,” Einstein wrote to Lindbergh. “To one who is outside of science the matter he will bring up may seem fantastic. However, you will certainly<br />
become convinced that a possibility is presented here which has to be very carefully watched in the public interest.” 9<br />
Lindbergh did not respond, so Szilárd wrote him a reminder letter on September 13, again asking for a meeting. Two days later, they realized<br />
how clueless they had been when Lindbergh gave a nationwide radio address. It was a clarion call for isolationism. “The destiny of this country<br />
does not call for our involvement in European wars,” Lindbergh began. Interwoven were hints of Lindbergh’s pro-German sympathies and even<br />
some anti-Semitic implications about Jewish ownership of the media. “We must ask who owns and influences the newspaper, the news picture,<br />
and the radio station,” he said. “If our people know the truth, our country is not likely to enter the war.” 10<br />
Szilárd’s next letter to Einstein stated the obvious: “Lindbergh is not our man.” 11<br />
Their other hope was Alexander Sachs, who had been given the formal letter to Roosevelt that Einstein signed. Even though it was obviously of<br />
enormous importance, Sachs was not able to find the opportunity to deliver it for almost two months.<br />
By then, events had turned what was an important letter into an urgent one. At the end of August 1939, the Nazis and Soviets stunned the world<br />
by signing their war alliance pact and proceeded to carve up Poland. That prompted Britain and France to declare war, starting the century’s<br />
second World War. For the time being, America stayed neutral, or at least did not declare war. The country did, however, begin to rearm and to<br />
develop whatever new weapons might be necessary for its future involvement.<br />
Szilárd went to see Sachs in late September and was horrified to discover that he still had not been able to schedule an appointment with<br />
Roosevelt. “There is a distinct possibility Sachs will be of no use to us,” Szilárd wrote Einstein. “Wigner and I have decided to accord him ten days<br />
grace.” 12 Sachs barely made the deadline. On the afternoon of Wednesday, October 11, he was ushered into the Oval Office carrying Einstein’s<br />
letter, Szilárd’s memo, and an eight-hundred-word summary he had written on his own.<br />
The president greeted him jovially. “Alex, what are you up to?” Sachs could be loquacious, which may be why the president’s handlers made it<br />
hard for him to get an appointment, and he tended to tell the president parables. This time it was a tale about an inventor who told Napoleon that he<br />
would build him a new type of ship that could travel using steam rather than sails. Napoleon dismissed him as crazy. Sachs then revealed that the<br />
visitor was Robert Fulton and, so went the lesson, the emperor should have listened. 13<br />
Roosevelt responded by scribbling a note to an aide, who hurried off and soon returned with a bottle of very old and rare Napoleon brandy that<br />
Roosevelt said had been in his family for a while. He poured two glasses.<br />
Sachs worried that if he left the memos and papers with Roosevelt, they might be glanced at and then pushed aside. The only reliable way to<br />
deliver them, he decided, was to read them aloud. Standing in front of the president’s desk, he read his summation of Einstein’s letter, parts of<br />
Szilárd’s memo, and some other paragraphs from assorted historical documents.<br />
“Alex, what you are after is to see that the Nazis don’t blow us up,” the president said.<br />
“Precisely,” Sachs replied.<br />
Roosevelt called in his personal assistant. “This requires action,” he declared. 14<br />
That evening, plans were drawn up for an ad hoc committee, coordinated by Dr. Lyman Briggs, director of the Bureau of Standards, the nation’s<br />
physics laboratory. It met informally for the first time in Washington on October 21. Einstein was not there, nor did he want to be. He was neither a<br />
nuclear physicist nor someone who enjoyed proximity to political or military leaders. But his Hungarian émigré trio—Szilárd, Wigner, and Teller—<br />
were there to launch the effort.<br />
The following week, Einstein received a polite and formal thank-you letter from the president. “I have convened a board,” Roosevelt wrote, “to<br />
thoroughly investigate the possibilities of your suggestion regarding the element of uranium.” 15<br />
Work on the atomic project proceeded slowly. Over the next few months, the Roosevelt administration approved only $6,000 for graphite and<br />
uranium experiments. Szilárd became impatient. He was becoming more convinced of the feasibility of chain reaction and more worried about<br />
reports he was getting from fellow refugees on the activity in Germany.<br />
So in March 1940, he went to Princeton to see Einstein again. They composed another letter for Einstein to sign, which was addressed to<br />
Alexander Sachs but intended for him to convey to the president. It warned of all the work on uranium they heard was being done in Berlin. Given
