Kay Summersby drove Dwight Eisenhower through the London Blitz in 1942. By 1944, she was a captain in the Women’s Army Corps, hand-picked by the Supreme Commander of the Allied Expeditionary Force to manage his schedule and guard his door. Four years later, Eisenhower’s own war memoir reduced her to a passing sentence about a driver. The most famous scandal of his presidency, a story that would dominate popular memory for half a century, began with a claim that Eisenhower asked permission to divorce his wife so he could marry his Irish driver, that General George Marshall refused in fury, and that President Harry Truman quietly ordered the incriminating letters burned.
None of it happened. The letters never existed. The story arrived through a dead president’s borrowed voice and outran every fact-checker for fifty years. Kay Summersby was born in County Cork, Ireland, in 1909, the daughter of a British father and an Irish mother.
She moved to London in her twenties, worked as a model, and in 1936 married a British officer named Gordon Summersby, keeping his surname long after the marriage lost meaning. She joined the Mechanized Transport Corps in 1939 and drove through the Blitz, threading cars down streets that occasionally stopped existing between one trip and the next. In May 1942, her motor pool assigned her to a visiting American major general named Eisenhower, a man few in Washington could have identified. By June, he commanded the European Theater of Operations, and she drove for him alone.
Dwight Eisenhower had married Mamie Dowd on July 1, 1916, in the Dowd family parlor in Denver. She was the daughter of a wealthy meat packer who spent winters in San Antonio, which is how a teenage girl from Colorado met a young Kansas lieutenant walking his rounds on a Texas parade ground in October 1915 and decided she wanted to know his name. John Dowd approved of the match despite the groom’s empty pockets, and something in the young man’s flat, unhurried confidence apparently did the work money could not. The army moved them thirty-three times in forty years, and Mamie, who hated alarm clocks and loved sleeping until noon, married straight into an institution assembled entirely out of alarm clocks.
Their first son, Dowd Dwight, arrived in September 1917, called Ikey by everyone. He ran the household from the moment he could walk and became the mascot of the tank crews at Camp Meade, who stitched him a miniature uniform. Scarlet fever killed him on January 2, 1921, three months past his third birthday. Both parents hunted for someone to blame, landed on each other, then landed on themselves, and the loss remained the greatest disaster of Eisenhower’s life, the one thing he could never entirely put down.
A second son, John Sheldon Doud Eisenhower, born in August 1922, did most of the closing of the distance between husband and wife. Eisenhower stopped writing about the boy he lost and mentioned him only once in a memoir published forty-six years later. Every year until his own death, he sent Mamie yellow roses on the birthday of the son who had died, with no note attached. By 1942, the marriage carried twenty-six years of transfers, a dead child, and a wife whose inner-ear disorder sometimes stole her balance and fed a rumor about drinking that followed her into the White House.
Biographers call the union structurally sound and thoroughly weathered. Eisenhower shipped out for London in June 1942 and came home in 1945 wearing five stars. Between those dates, he wrote Mamie 319 letters, every one of them opened and read by a censor before it reached her hands. Not a single one of her replies survives.
She waited out the war in a hotel apartment on Connecticut Avenue, three thousand miles from her husband. Eisenhower rented Telegraph Cottage, ten miles outside London, a small brick house with a rose garden and a patch of lawn he used as a private golf hole. His naval aide, Harry Butcher, kept a diary, and that diary supplies most of what anyone can honestly say about the next three years. Butcher recorded the horses at dawn, the bridge games running past midnight, and the plain fact that Kay Summersby and the Supreme Commander became inseparable.
A man responsible for the lives of three million soldiers spent his evenings playing bridge with a woman who called him Ike. Butcher framed all of it as morale: the Supreme Commander carried the invasion of a continent in his skull, smoked four packs of Camels a day, and needed one room on the planet where nobody addressed him as sir. Kay ran that room. Eisenhower called the arrangement companionship and printed the word in a book published in 1946, while every person involved could still sue him over it.
That book cooled a long friendship. Ordinary details built the rumors. The cottage, the horses, the Scottish terrier named Teak that Ike and Kay shared like a joint custody arrangement. Everyone around them noticed, and nobody wrote it into an official report because an official report would end a career.
Kay met an American colonel, Richard Arnold, accepted his proposal, and began planning a wedding that required only one administrative miracle, the final clearing of his divorce through an American court. In June 1943, a landmine killed him in North Africa. By her own account, published thirty-three years later, Eisenhower sat with her while she came apart, and something in that room moved from professional into territory neither of them ever named out loud. That account deserves suspicion.
Its only witness published her version while liver cancer killed her, and the manuscript passed through two ghostwriters. The rumor crossed the Atlantic faster than the mail. Washington dinner parties traded the story of the general and his driver like currency. American newspapers printed photographs of the Supreme Commander with a young Irish woman in uniform standing near his car, and the captions named her and spelled her rank.
Mamie wrote to her husband about it, more than once. Her letters do not survive, which leaves historians reading his answers and reverse-engineering the questions that must have provoked them. In early 1943, he told her to stop worrying, insisting he did not care a tinker’s damn about anyone else. That March, he assured her flatly that she carried no reason to feel jealous of anyone.
Twice more that year, he begged her, in the strange pleading register of a man who spent his working hours ordering other men to die, not to worry about him. Read those letters as denials and they look like denials. Read them as a man defending something he cannot afford to lose and they look like exactly the same thing. Mamie kept every one of them.
By 1944, Kay Summersby no longer drove anything. She managed Eisenhower’s private correspondence, screened his appointments, listened to conversations a British civilian held no clearance to hear, and sat in the tightest circle at Supreme Headquarters. That created an administrative problem the army solved in the most army way imaginable. In October 1944, at Eisenhower’s personal request, the army commissioned her as a captain in the Women’s Army Corps, a foreign national.
The paperwork moved anyway. American citizenship followed. An Irish-born British subject received a United States Army commission because the Supreme Commander wanted her within reach, and not one person in that chain of command left behind a written objection. Germany surrendered in May 1945.
Within a year, the machinery that built Kay Summersby a career quietly took the career apart. The army posted her to Berlin under General Lucius Clay. Eisenhower ordered her to prepare typescripts of his wartime diaries, so her final official months were spent transcribing the record of the year she spent beside him. Then she sailed for the United States in late 1946.
He never added her to his Washington staff. The letters stopped, and so did the phone calls. Whatever the two of them wanted from each other in the summer of 1944, by 1947 it existed only in the past tense. A woman who spent three years within arm’s reach of a five-star general could not pry a single reply out of him.
No memo survives to name the person in Washington who decided the matter. A staff list circulates without a name on it. An invitation fails to arrive. A memoir goes to the printer with one subordinate clause where three years of a woman’s life belonged.
In 1948, Eisenhower published Crusade in Europe, a bestseller that taught a generation what the war looked like. Kay Summersby appears once. He mentions a driver in passing and moves on. That same year, she published her own memoir, Eisenhower Was My Boss, ghostwritten by the journalist Frank Kearns.
It describes a warm and utterly chaste arrangement between a lonely general and a devoted aide, and it lands with all the spontaneity of a document reviewed by somebody’s attorney. Whether the army or the publisher sanded that memoir down remains an allegation rather than a finding. Twenty-six years passed. Harry Truman died in 1972.
In 1974, the writer Merle Miller published Plain Speaking, an oral biography assembled from interviews Miller conducted with the old man in Independence, Missouri. Inside it, Truman supposedly described the 1945 letter, the request to divorce Mamie, and Marshall’s incandescent refusal. He supposedly added that he ordered those letters retrieved from the Pentagon and burned. The story arrived carrying everything a scandal needs: a dead source, a famous villain, a virtuous protector, and no paper trail whatsoever.
The tapes of Miller’s interviews still survive in an archive anybody can visit, and the passage about the letter does not appear anywhere on them. Archivists at the Truman Library have combed the record repeatedly and turned up no order and no memo. Forrest Pogue, Marshall’s official biographer, stated flatly that no such letter ever existed. Robert Ferrell, a careful Truman scholar, demonstrated that Miller fabricated or wildly inflated a whole run of quotations.
The letter sits in no archive, and people have hunted hard because a researcher who found it would never pay for a lunch again. Kay Summersby married a Wall Street stockbroker named Reginald Morgan in 1952 and divorced him in 1958. Then she vanished into a quiet New York life. Liver cancer arrived in the 1970s, and a publisher arrived not long after.
The first ghostwriter, Septé Hayden, reportedly produced a version in which the affair reached physical consummation. The final manuscript, assembled by Barbara Wyden, claimed something stranger and sadder: that the two attempted sex on two occasions and that Eisenhower, wrecked by exhaustion, could not manage it. A book selling itself as the confession of Eisenhower’s mistress contains at its center an admission that the affair collapsed on both of the two nights it supposedly took place. No publisher invents a detail that deflating.
That single passage keeps serious historians from throwing the whole memoir out, and it also keeps them from believing a word of the rest of it. Two ghostwriters, two versions, one dying woman, and no way now to ask her which paragraph she actually spoke aloud. Kay Summersby died on January 20, 1975. Her memoir reached bookstores the following year.
She never saw it, never approved a final page, never answered a reporter about a single line. During the 1952 campaign, the rumor moved through Democratic circles as a whisper, useful precisely because nobody would print it. It returned in 1956. Mamie answered both times by becoming the most aggressively ordinary woman in America: bangs, a pink dress, and a public performance of contented housewifery so total that the country stopped asking questions.
The memoir reached her at age seventy-nine, a widow living on the Gettysburg farm. She issued no statement. Her family answered instead. In 1978, her son John published Letters to Mamie, a stack of his father’s wartime correspondence aimed straight at the affair.
Eighteen years later, granddaughter Susan Eisenhower produced her own biography of Mamie that dismisses the whole Summersby story as an invention of gossips and opportunistic publishers. That never quite explains the captain’s commission. Strip out the letter, the ghostwriters, the deathbed manuscript, and the borrowed voice of a dead president, and one question survives: whether a man can betray his wife without ever laying a hand on another woman. The strongest evidence for the affair comes from a book its own author never approved.
The strongest evidence against it comes from letters a husband wrote knowing a censor would read them before his wife did. Michael Korda, in his 2007 biography, argues the relationship crossed into love in everything except the physical act, and that the army understood this perfectly and shielded it anyway. Steven Ambrose and Gene Edward Smith both conclude that Eisenhower, buried under a pressure no human being should absorb, needed a woman’s company the way other men needed whiskey, pointing at the practical obstacles: an aide outside every door and a Victorian conscience formed in a Kansas house. The physical affair very probably never occurred.
None of that lets him off the hook. Something crossed a line in that cottage, and the institution recognized the crossing, hid it, promoted the woman while it needed her, and deleted her the instant it stopped needing her. Mamie outlived her husband by ten years. She stayed on the farm, surrounded by the photographs and letters she carried through Panama, Paris, and Manila.
She told anybody who asked that the country won its war on the strength of a partnership conducted inside her own house. She never conceded an inch. Mamie’s version of the marriage reached the encyclopedias and the schoolbooks, and it remains the version most people repeat today. She died on November 1, 1979, at Walter Reed.
They carried her to a chapel in Abilene, Kansas, and set her beside Ike and beside the three-year-old boy the two of them lost in 1921. Three names under one roof. The army buried Kay Summersby with paperwork rather than fire, and she disappeared from the official history of the war she helped run. The affair the tabloids wanted probably never occurred.
The betrayal that did occur never required a bed.
