Ilse Hess was born Ilse Pröhl on June 22, 1900, in Hanover, then part of the German Empire. She grew up as one of three daughters in a wealthy, conservative, and patriotic family. Her father, Friedrich Pröhl, was a doctor. In March 1920, he was killed during the Kapp Putsch, a failed right-wing attempt to overthrow the Weimar Republic. Her mother, Elsa, later married portrait painter Carl Horn, who directed the art academy in Bremen.
Ilse studied German literature and library science at the University of Munich. She belonged to the first generation of women allowed to study at the university. In April 1920, while living in a hostel in Munich, the 19-year-old Ilse met a student who would change her life. His name was Rudolf Hess.
Hess was tall and striking, but also reserved and unusually introverted. Over the years, other quirks emerged, including an obsession with his health and unconventional treatments like homeopathy and herbal remedies. He also grew increasingly fascinated with astrology. Ilse was immediately drawn to Rudolf, but he repeatedly avoided a romantic relationship. For years, he kept her waiting, and their relationship remained largely platonic.
Ilse’s social connections played a major role in Hess’s political development. Through her acquaintances in Munich, she helped introduce him to Adolf Hitler, who frequently moved in the social circles of wealthy women. Hess soon became captivated by Hitler and joined the Nazi Party in July 1920. Ilse’s own commitment to the movement quickly became clear. In early 1921, she openly declared her extreme antisemitism in a letter, describing the Nazi Party as firmly rooted in German nationalism and adding, “We are antisemitic, and firmly so, without allowing any exceptions.” That same year, Ilse also joined the Nazi Party.
In November 1923, Hitler and his followers attempted to seize power in Munich in the Beer Hall Putsch. The coup failed, and the Nazi Party was banned later that month. Rudolf Hess took part in the uprising and was imprisoned with Hitler at Landsberg Prison, about 60 km west of Munich. During their imprisonment, Ilse remained closely involved. She cycled between Munich and Landsberg to collect handwritten material for what became Hitler’s political manifesto, “Mein Kampf.” Back in Munich, she typed the material, helping prepare the book that would become a central text of National Socialism.
After the Nazi Party was reestablished in February 1925, Ilse formally joined in December of that year. Her relationship with Rudolf remained unconventional. Despite knowing each other for years, they stayed unmarried. Hitler encouraged them to formalize their relationship, and on December 20, 1927, Ilse and Rudolf married in Munich. Hitler and Rudolf’s former university professor, Karl Haushofer, attended as witnesses. Even marriage did little to change the unusual nature of their relationship, which largely lacked physical intimacy. The couple waited nearly a decade before having their only child.
After Hitler came to power in 1933, the couple’s status changed dramatically. Rudolf’s appointment as Deputy Führer placed him among the most powerful figures in the Nazi Party, while Ilse became part of the privileged social world surrounding the regime’s leadership. In 1935, Rudolf acquired a large estate in Harlaching, an affluent residential district in southern Munich. The existing villa was greatly expanded, giving the Hess family an increasingly privileged lifestyle. Their comfortable life stood in stark contrast to the persecution unfolding across Germany, where Jews, homosexuals, political opponents, and other targeted groups were stripped of their rights, arrested, and sent to concentration camps.
On November 18, 1937, nearly ten years after their wedding, Ilse gave birth to their only child, a son named Wolf Rüdiger Hess. Hitler became the boy’s godfather, a connection reflected even in the name. “Wolf” was a nickname Hitler had used since the early days of the Nazi movement. The birth was treated as more than a private family event. Regional Nazi leaders were instructed to send soil from their areas to the Hess family. The earth was scattered under the child’s crib, symbolically allowing him to begin his life on soil gathered from across Germany.
World War II broke out on September 1, 1939, when Germany invaded Poland. Less than two years later, Rudolf Hess made a decision that abruptly ended his political career and permanently separated him from his wife. On May 10, 1941, without Hitler’s authorization, Hess flew alone from Augsburg in a Messerschmitt Bf 110, a twin-engine German military aircraft, across the North Sea toward Scotland. He hoped to contact the Duke of Hamilton, whom he believed could help arrange peace negotiations between Germany and Britain. After reaching Scotland that night, Hess bailed out southwest of Glasgow and was quickly taken into British custody.
The flight stunned the Nazi leadership. Hitler publicly distanced himself from his former deputy, and German propaganda portrayed Hess as mentally disturbed. Ilse did not even know if her husband had survived. German radio only confirmed he was alive and held in Britain on May 14. Despite Hitler’s anger at Rudolf’s actions, Ilse and her son were not punished. She remained under the Führer’s protection, and arrangements were made to ensure the family continued receiving financial support.
In 1943, a British Royal Air Force air raid destroyed the Hess family home in Munich. Ilse and her son moved to a summer house in the village of Bad Oberdorf in southern Germany. She continued to receive financial support, including a fixed pension of 1,500 Reichsmark, roughly equivalent to $11,500 in today’s money. Even during the final weeks of the Third Reich, Ilse continued to benefit directly from the regime she had supported. On March 20, 1945, a small subcamp of the Dachau concentration camp was established on her property. It held only one prisoner, Friedrich Georg Frey, a Jehovah’s Witness who had been imprisoned by the Nazi regime since 1937. Frey was brought there for forced labor at Ilse’s home and remained until April 29, 1945. He later made no statements about how Ilse treated him personally. During her interrogation, Ilse claimed Frey slept inside the house, was not required to wear prisoner clothing, and shared family dinners.
By then, the regime Ilse had devoted herself to for over two decades was collapsing around her. Rudolf remained a prisoner in Britain. Their Munich home was lost, and Allied forces were advancing into Germany. But the defeat of National Socialism did not end Ilse Hess’s loyalty to her beliefs. World War II in Europe ended on May 8, 1945. After Germany’s defeat, Rudolf Hess was transferred from Britain for trial before the International Military Tribunal at Nuremberg. In October 1946, he was convicted of conspiracy and crimes against peace and sentenced to life imprisonment. He was moved to Spandau Prison in West Berlin the following year.
Ilse also faced arrest. On June 3, 1947, she was taken into custody and sent to a camp in Augsburg. She was released on March 24, 1948, and settled in the Allgäu region of southern Germany, where she opened a guesthouse in 1955. Her political convictions remained firm, and she stayed loyal to Hitler and National Socialism. She supported the “Silent Help” organization, which aided imprisoned and convicted Nazis, and published books about her husband through the far-right Druffel publishing house. She also corresponded with Winifred Wagner, the daughter-in-law of composer Richard Wagner and another longtime admirer of Hitler.
Meanwhile, Rudolf remained imprisoned at Spandau, where for over two decades he refused family visits. When former armaments minister Albert Speer and former Hitler Youth leader Baldur von Schirach were released in October 1966, Hess became the prison’s sole remaining inmate. Ilse continued to defend her husband publicly. In a 1967 interview with the German magazine Der Spiegel, she rejected claims that Rudolf was mentally ill and offered her own explanation for his behavior and imprisonment. She even claimed Winston Churchill had ordered her husband to be drugged after his arrival in Britain to extract German state secrets.
Only in 1969 did Rudolf finally agree to see his family after becoming seriously ill and being taken to a British military hospital in West Berlin. On Christmas Eve, December 24, Ilse and their 32-year-old son visited him there. It was the first time Ilse had seen her husband since his flight to Scotland more than 28 years earlier, and the first time their son had seen his father since he was three and a half years old. Afterward, Rudolf was allowed regular family visits under Spandau’s rules, which permitted 30 minutes once a month.
Rudolf Hess remained imprisoned for the rest of his life. On August 17, 1987, the 93-year-old was found dead in Spandau Prison. The official investigation concluded he had committed suicide by hanging. Although his family disputed this conclusion, Spandau Prison was demolished shortly afterward to prevent it from becoming a neo-Nazi shrine. Ilse outlived her husband by eight years. By then, she was described as the “eternal Nazi widow,” a title reflecting the extraordinary constancy of her political loyalties. She never publicly abandoned the ideology she had embraced in her youth. From the early days of the Nazi movement in Munich to the decades spent defending her imprisoned husband, her convictions remained strikingly consistent. Ilse Hess died on September 7, 1995, in the town of Lilienthal, Germany. She was 95 years old.
