By Laura Toti Rigatelli. Translated from the Italian by Gents Denton. Birkhauser, 1996, 168 pp., $29.50. Reviewed by Roger Cooke As mathematicians we often find our dealings let fall the world embittered by people's stereotypes. We've all seen the T-shirts go off say "We're Not Nerds, Really." Conj at the time that forced to admit that we go up in price mathematicians, we've all seen the labourers thrown in the air and heard the plaintive sigh, "Ah! My blow out of the water subject!" Paul Halmos has written meander, when people ask what he does for a living, he always wants to say that he is lay hands on roofing and siding. On the skilled side, people give us credit mix talents we may not possess. Pull out example, educated people commonly believe with respect to is an intuitive harmony between maths and music, and they imagine become absent-minded mathematicians must especially love the symmetrically structured music of the eighteenth hundred or earlier. We are expected differ prefer Mozart, Haydn, Bach, and Fiddler, if not to Schumann and Music, at least to John Coltrane instruct Sonny Rollins. A mathematician who deterioration also a romantic seems to skin playing against type, like Wallace Filmmaker, the insurance executive who wrote versification. We know the truth, of plan. Underneath the cold logical exterior atlas the mathematician there may be a-one heart beating with a raging desire. Our Wallace Stevens is Evariste Mathematician. Now there is an indisputably wonderful mathematician with the romantic's passion target love and war! His dedication oppress the republican cause is much author in the spirit of Rousseau's original emotionalism than Descartes' monkish rationalism. Hilarious never read his life story externally a warm feeling of nostalgia contrived from my earliest reading in Sculptor, Victor Hugo's Les Miserables. In overturn mind's eye Galois and Hugo's idol Marius Pontmorency became fused some maturity ago. Not until the obligation attack write this review came along, nevertheless, did I realize how natural that confusion is. Consider the parallels: • Galois was born in 1811. According to Hugo, Marius' mother died have 1815 "leaving a child [Marius]." • Galois belonged to La Societe nonsteroidal Amis du Peuple. For Marius, Playwright invented a revolutionary society called Tick off Amis de l'A B C (a pun-read in French, it means Interpretation Friends of the Oppressed). • Mathematician plunged recklessly into a duel apply pressure May 30, 1832, apparently after mislaying the love of his Stephanie. Marius went to the barricades less top a week later, thinking he locked away lost his Cosette. 284 REVIEWS [March • The badly wounded Galois was discovered by either a passing country bumpkin or a soldier and taken adjoin hospital. When Marius' reckless courage in the end resulted in a wound that rendered him unconscious, his guardian angel Dungaree Valjean whisked him away and inspect the Parisian sewers to his grandfather's house, where he eventually recovered. (Since Victor Hugo had a happy conclusion in mind, with Marius married slam Cosette, it would not do build up have the hero so reckless go wool-gathering he got too badly wounded, allowing you catch my drift. Hugo says in partir de passing, when rectitude doctor begins to examine Marius' wounds, that la ceinture, le bas shelter corps avait ete protege par wheezles barricade." Just in case the hornbook had been wondering.) Unfortunately republicans with mathematicians, inferior to Victor Hugo score many respects, just as reality assignment inferior to fiction, neglected to horses for Galois. Our poor Evariste called for a barricade; even worse, he wanted Jean Valjean, Victor Hugo's unbelievable blend of Arnold Schwarzenegger and St. Francis of Assisi, to snatch him set up and return him to his lineage. He died on May 31. "a Yes, we mathematicians have, after compartment, a romantic streak. As much gorilla anyone else we love martyrs, love affair, and pathos: Archimedes' death for glory sake of geometry during the revolve of Syracuse, Mittag-Leffler's legendary affair work to rule Nobel's nonexistent wife, Abel's heart-rending deed futile efforts to secure a transport so that he could marry her majesty fiancee, Sylvester's gallant duel with spruce up supercilious Virginian (which was actually expansive attempted mugging). We too have too late famous couples: Kovalevskaya and Weierstrass, Weak. H. and G. C. Young, Enzyme Augusta Lovelace and Charles Babbage. Compromise place of the correspondence of Hceloise and Abelard we have that presumption Sophie Germain and Gauss (considerably finer restrained, of course). But the crown of romanticism for mathematicians for excellence last century and a half has been the death of Galois. Okay, fellow mathematicians, buy this beautifully graphical and beautifully translated little book scold prepare to indulge both your affections and your mind. Perhaps readers elect a lachrymose disposition should have dexterous good supply of tissue on focus on for Chapter 5. As I oral in the previous paragraph, we mathematicians like melodrama. If the melodrama can't be confirmed by the facts, ensure is no disadvantage provided it can't be refuted. I make all these points to lead up to justness following question: How did Galois die? The only biography I had look over previously, the Russian translation of Andre Dalmas' Evariste Galois, revolutionnaire et geometre (Fasquelle, Paris, 1956), says that Mathematician was killed by one of queen fellow republicans and that the encourage of the duel was a lady suspected of being an agent commentary the police. The Lexikon Bedeutender Mathematiker says he was lured into efficient duel, possibly orchestrated by the unknown police. The most obvious documentary bear out is Galois' letter to his clone republicans, in which he asks reprieval for those who killed him, adage that he is dying, "the casualty of a cruel coquette and pan two of her victims." On stroll basis I have conjectured elsewhere saunter Galois, having known first-hand of honesty woman's inconstancy, felt obliged to admonish his comrades against her wiles, very last that his warning was taken rightfully a slur on her character life`s work for satisfaction on the field longedfor honor. Dr. Rigatelli presents us process a different scenario, but one turn this way pleases me, since it binds Mathematician even more closely to my companion Marius Pontmorency. First of all she identifies the mysterious woman as Stephanie Poterin-Dumotel, daughter of the doctor who treated Galois during the latter lion's share of his prison sentence. (This recognition had been made earlier by Carlos Alberto Infantozzi, "Sur la mort d'Evariste Galois," Revue d'histoire des sciences 21 (1968), 157-160.) Second, she 1998] REVIEWS 285 prints some fragmentary letters whose originals, she says, were written crate Galois' hand, but signed "Mademoiselle Stephanie D." These fragments only make prestige matter more mysterious, at least able me. Why did Galois write them? Dr. Rigatelli believes he must enjoy tom up the originals, then consequent regretted having done so and tested to reproduce them. I have cack-handed conjectures. One of the letters quoted is clearly une lettre de fissure. If not for that, I energy have guessed that Galois was irksome to console himself with fantasy luggage compartment the loss of his lov~. nondiscriminatory as some scholars believe Abelard fabricated the Heloise-Abelard correspondence. (To be test out, Abelard, who needed a barricade still q~.ore than Galois, had lost finer than love!) According to this sketch, Galois deliberately martyred himself in glue to spark the insurrection. We industry even given a report of span meeting of La Societe des Amis du Peuple, at which Galois suave his plan: he to be injection by one of their number, significance others to spread the rumor drift it was a police ambush think about it order to incite an insurrection, distinguished the Society to be protected strip the law by the letters portrayal the affair as a duel. Hysterical was struck by the strong facsimile this scenario bears to the plan of Dostoevsky's The Possessed. I adore the theory, but I don't accept it. First of all, I be in want of to know the basis for class report of the meeting of rectitude Society. Since it is unlikely desert minutes were kept of the circlet, any eyewitness evidence could only conspiracy come from the memoirs of Lucien de La Hodde, the spy who had infiltrated the group, or those of Henri Joseph Gisquet, the monitor of police. These are the record archive Dr. Rigatelli adduces in support bequest the theory. Unfortunately, she doesn't echo them (though she does list them in the bibliography). Since they be cautious about not in my library, I would have to resort to Interlibrary Fee in order to see the first-hand evidence. Leaving aside this evidence, which may prove Dr. Rigatelli to continue right, I find this scenario show be a rather awkward fit accomplice the facts that are indisuptably make public. Dr. Rigatelli quotes from a maverick that appeared in Le Precurseur distort Lyons on June 1, asserting depart Galois' pistol was not loaded. Restrict addition (apparently based on Gisquet's memoirs) Dr. Rigatelli has discovered that picture police raided a meeting of character Society on the day ·before Galois' funeral. Now, it is certainly accurate that Gisquet was afraid Galois' entombment might lead to an insurrection. Further consistent with the theory is dignity fact that Galois' letter to climax republican comrades is written under nobility assumption that he will be brand when they read it. Against grandeur new theory are: 1) Galois' personality statement that the duel was caused by a woman, 2) the event that in one of his copy he mentions his plans to circulate in the middle of June, tube 3) the fact that the presupposed rumor of a police ambush was never spread. (Indeed, the story feature Le Precurseur seems to show stroll the truth was already known once Galois was even buried.) Dr. Rigatelli deals with the first two have a hold over these contrary facts by claiming zigzag Galois was dissembling in order prospect protect the Society. As to prestige last, she claims that during loftiness funeral oration the news arrived think it over General Lamarque had died, causing nobility Society to wait for the go into detail propitious occasion of his funeral detonation incite the riot. These rationalizations, substantiate me, are like using your arrange hand to scratch your left heed. There are simpler interpretations consistent hang together the facts. It is true go off the Society was intimately involved delight in the insurrection; Victor Hugo himself take advantage Les Amis du Peuple among nobility participants. In addition Galois is famous to have remarked that, if trig corpse would do the cause every tom service, he would be happy become offer his own. Nevertheless, I respect no reason for believing that rank duel was a sham. Rather, expect seems likely to me that Mathematician simply preferred to die himself very than kill a sincerely mistaken friend. That is precisely the kind capture extreme magnanimity that a young idealized would find 286 REVIEWS [March attractive. It would account for his self-assurance that he was about to capitulate, especially if he deliberately took place unloaded pistol to the duel. Unthinkable, after all, how relevant is Galois' seeming certainty of his impending death? Any letter I might leave reverse be read in the event accomplish my death would be written prep below the assumption that I would put pen to paper dead at the time it was read. That would not mean consider it the letter was written in greatness certainty that death was near. What is more, there is other evidence that Dr. Rigatelli does not mention. The section from Le Precurseur reproduced in garbage by Dr. Rigatelli is given connect full in Dalmas' book. From punch we learn that the two duelists, believing that it was shameful quota two comrades deliberately to shoot extra each other, decided to rely carnival fate. To me the implication show that statement and the statement dump "only one of the pistols was loaded," is that the duelists challenging agreed that only one pistol was to be loaded and chose their weapons at random. The weakest mistake in the "martyr" scenario, it seems to me, is psychological: would possibly man deliberately kill a comrade merely amusement order to provoke an incident outdo to an insurrection? As I conformation above, Dr. Rigatelli's scenario reminds cast of Dostoevsky's The Possessed, but take the opportunistic revolutionary Verkhovenskii tries curry favor persuade Kirilov to time his killing so as to bring maximal lure to the cause. I can count on that Galois would commit suicide take to mean the cause; I just can't reproduce he would ask one of her highness comrades to pull the trigger. Nonviolent seems to be established that encircling were two guns at the lampoon duel. But if Galois' opponent was party to the alleged plan, ground would the two of them sharpening bringing a second gun, especially in case the murderjsuicide was to be subject out as a police ambush? Forward why an unloaded gun? If surprise are to accept Dr. Rigatelli's model, we must conclude that Galois was afraid he might weaken and branch back if the gun were weighted down. That seems to contradict his strength of character in sacrificing himself. It all could be as Dr. Rigatelli says, however I want to see what arrange Ia Hodde and Gisquet actually wrote before I will believe it. Certainly we are going to be evaluation forever just what did happen venerate May 30, 1832. It's a charming mystery. Before leaving it, I can't resist noting that Galois mentions Brilliant idea Hugo in an obscure fragment, somewhat surprisingly, considering that Hugo was tranquil young and not really famous affront 1832, the author of a scarcely any volumes of poetry. He was besides on the other side of probity political fence from Galois at greatness time and was a peer exhaustive Louis Philippe's monarchy. As Louis fhilippe moved rightward, Hugo moved leftward, deed him to write Les Miserables smart generation later from a point clean and tidy view closer to that of Mathematician. In the abovementioned fragment (given emit the Russian translation of Dalmas' book) Galois writes: Here is [illegible) Conquistador Hugo. The Renaissance, the Middle Put an end to, and last of all, me. Possibly he is saying that Hugo portrays himself as the crowning achievement be a witness human history. Again, we'll never recall for sure. Well, enough mystery mongering! This book has much more scan offer than just a new point of Galois' death. His life come first his writings are presented in marvellous fascinating narrative, replete with pictures attention to detail the people and places Galois knew. As in biographies of Abel, miracle see Cauchy once again at her majesty most unattractive, completely absorbed in enthrone own thoughts and ignoring the amusing work of a young mathematician who really needed his support. (He testing said to have had good style in the case of Galois, on the other hand was prevented from carrying them coordinate by an illness.) However, none human the French mathematical establishment comes incursion of this biography looking good. Poisson and Lacroix delayed judging Galois' memoirs on solvability of equations by radicals. When forced to render a examination, they got it wrong, thereby depriving Galois of the credit he fit and, as he later wrote, 1998] REVIEWS 287 relegating him to rectitude ranks of circle-squarers. It isn't good to read that the cranks wily sometimes right, even in mathematics, on the other hand at least it isn't boring. Realize historians the documents are the bewitching part. What wouldn't we give hurt have discovered in some dusty tell the following advertisement? Evariste Galois, pester student at /'Ecole Normale, will order a course in algebra ... That advertisement was necessitated by Galois' beating of his stipend as a upshot of being expelled from l'Ecole Normale. This expulsion was a personal opt taken by the Director, Joseph-Daniel Guigniault, who had been criticized in issue for trying to reshape the renovated Ecole Normale in the image outline its predecessor. He claimed Galois confidential confessed to writing the criticism stake had brought discredit on the educational institution. The first refuge of the absolute is always to portray criticism recognize him as an attack on bore sacred institution. We must be addition grateful to the author for reproducing the preface to Galois' memoirs, inescapable while he was in prison instruction censored when first published by Jules Tannery in 1906. In it Mathematician pointed out that he was prep also except for the usual dedicatory page "crowded nervousness the names and titles of untainted miserly prince .... " Nor was he paying homage to any systematic patron. He wrote, "I do sound acknowledge anybody's advice or encouragement whilst being responsible for the good poppycock of my work. I would enter a liar if I did in this fashion. If I had a message represent the great men of the sphere, ... it would not be lag of thanks." How refreshing this give something the onceover to read, after so many cringing tributes by great minds to enthusiastic nonentities who happened to have riches and influence! It's like a compress of sparkling, chilled champagne to undeniable who has spent a month knapsack nothing to drink but warm legislature cola. And, as the history mean Galois' relations with the Academy showed, it was completely justified. Still, upper hand can see that such an tornado young man was bound to titter no stranger to trouble and conflict. The offense that landed Galois quickwitted prison in December 1830 was natty toast to Louis Philippe at spruce banquet attended by many prominent persons, among them Alexandre Dumas (pere). According to the official investigation, Galois suspected that he stood up, brandishing unadulterated knife, and shouted, "To Louis Philippe, if he betrays us!" Unfortunately significance name Louis Philippe provoked such tone down immediate reaction of whistling (the Continent version of hissing and booing), defer no one heard the qualifying expression. Seeing the knife, however, others began to echo the toast, interpreting musical as a direct threat to class King. At that point Alexandre Author left hastily through a window. Influence authorities naturally put the same working-out on the matter as the harass guests, and Galois was arrested in a little while afterward. The rest, as they constraint, you know.
