Therese Brunsvik de Korompa (1775–1861)
A life shaped by music, pedagogy, and silent devotion
The eldest daughter of Count Anton Brunsvik and Anna von Seeberg, Therese was born in 1775 into one of Hungary’s most influential noble families. Raised between the estates of Martonvásár and Korompa, she received a refined education and soon distinguished herself for intelligence, sensitivity, and a strong reformist spirit.
In 1799, together with her mother and her sister Josephine, she entered the Viennese salons where she met Ludwig van Beethoven. A deep friendship grew between them, nourished by mutual esteem and a shared educational ideal. Therese was briefly his pupil, and in 1810 Beethoven dedicated to her the Sonata in F‑sharp major, Op. 78.
Her correspondence and diaries — invaluable historical sources — reveal not only her bond with Beethoven but also the central role she played in protecting and supporting her sister Josephine, especially during the most difficult years of her life.
A passionate advocate of Pestalozzi’s educational principles, Therese devoted herself to early childhood education and to the promotion of women’s rights. She founded the first kindergartens in Hungary and fought for social equality in Budapest. She never married, but became a spiritual mother to many children, including the mysterious Minona, Josephine’s daughter, whom she raised with love and discretion.
Therese died in 1861, leaving behind a legacy of pedagogical innovation and a unique testimony to the inner world of Beethoven and his circle.
Josephine Brunsvik de Korompa (1779–1821)
The countess who loved Beethoven — and paid the price of her nobility
Born in 1779, the second daughter of Count Anton Brunsvik and Anna von Seeberg, Josephine grew up amid the splendor of Hungarian aristocracy and the constraints of a strict upbringing. Gifted with grace, intelligence, and deep musical sensitivity, she entered the Viennese salons in 1799 with her mother and sister Therese, where she met Ludwig van Beethoven.
Between them arose a bond that was profound, passionate, and tormented. Josephine was his pupil, muse, and confidante. After her marriage in 1800 to Count Joseph Deym — a union of convenience rather than affection — the correspondence with Beethoven ceased, only to resume intensely after Deym’s death in 1804. Their letters, filled with longing and sorrow, reveal a relationship that challenged social conventions and the rigid boundaries of class.
Widowed and mother of four, Josephine found herself torn between her love for Beethoven and the legal and familial pressures that prevented her from marrying a man of non‑noble birth. Her life was marked by imposed choices, including a second, unhappy marriage to Baron Christoph von Stackelberg, with whom she had additional children.
In 1813, Minona was born — a mysterious child never officially acknowledged. Therese, ever devoted, took her in and raised her. The circumstances of Minona’s birth — and even her name, an anagram of “Anonim” — have long fueled the belief that Beethoven was the father.
Josephine died in 1821, worn down by illness and a life of renunciation. Today she emerges as a woman divided between duty and passion, nobility and freedom, motherhood and an impossible love.
Adam (Ádám) von Stackelberg (1787–1841)
The Baltic baron who became Josephine’s second husband
Adam von Stackelberg, born in 1787 into a Baltic noble family, belonged to the cosmopolitan world of the imperial aristocracy that moved between Vienna, Livonia, and the courts of Central Europe. Young, polished, and ambitious, he quickly entered diplomatic and military circles, where he distinguished himself for elegant manners and a taste for social life.
In 1810 he met Josephine Brunsvik, already widowed from Count Deym and mother of four. Their marriage, celebrated the same year, was welcomed by both families: a “suitable” union that promised Josephine renewed social stability and offered Stackelberg a stronger position in Viennese and Hungarian society. Reality, however, proved very different.
Often absent due to travels and appointments, Stackelberg soon revealed an unsettled character and little inclination toward family responsibilities. His relationship with Josephine’s children was strained, and the couple’s financial situation deteriorated rapidly. Letters and diaries by Therese Brunsvik describe growing tensions, misunderstandings, and an emotional estrangement that became irreversible.
In 1813, Minona was born — the most enigmatic child of the Brunsvik family. Stackelberg never recognized her as his own, and shortly thereafter abandoned Josephine entirely, relinquishing any role in the household. The separation left Josephine in a state of material and emotional fragility, while Therese assumed responsibility for the children.
After leaving the family, Stackelberg continued his career through various administrative posts and travels in Eastern Europe. He died in 1841, far from the Brunsvik circle — an elegant yet elusive figure, more spectator than protagonist, but nonetheless decisive in shaping Josephine’s fate and the still‑debated story of Minona’s birth.
Therese Brunsvik and the Birth of Minona
In her memoir Mein halbes Jahrhundert, Therese von Brunsvik declared not only that she was the “godmother” of the child, but wrote quite literally: “Das Kind wurde mir förmlich geschenkt” (“the child was literally given to me”). The reason for this statement is clear: since Josephine was not yet legally divorced, Therese wished to prevent Count Christoph von Stackelberg from claiming any rights over this child of love. She also wanted to protect the newborn from the constant conflicts between Josephine and her husband, quarrels that had already deeply affected the other children.
Josephine never kept the secret from her sister. Therese was informed of the pregnancy from the very beginning. In her diary entry of 22 September 1812, she wrote:
“Josephines Kind will ich nicht als das meinige ansehen, sondern es für seine Eltern mit der größten Verleugnung und wie es Pflicht ist, erziehen…” (“Josephine’s child will not be as if it were my own, but I shall raise her for her parents, with the greatest self-denial, as duty requires…”)
As for von Stackelberg, he respected a tacit agreement to stay away from his wife. Therese later noted in her diary: “Wir sahen ihn sechs Monate nicht” (“We did not see him for six months”).
Yet on 4 December 1812, without warning, the count returned briefly to Vienna. His attitude toward Josephine remained unchanged: cold, distant, and devoid of any marital relationship.
Josephine’s Flight and the Birth of Her Child
Josephine, pregnant during this turbulent period, made a drastic decision: as Therese recounts, she “packed clothes and linen and decided to leave the house.” It is unclear whether von Stackelberg remained in Vienna in the following months; however, on 20 March 1813 — shortly before the birth — he drafted a new marital contract. Its final sentence was stark:
“Du bist frey – wie Du selbst mit Dir rechnen willst.” (“You are free — but you must rely solely on yourself.”)
A few days later, Stackelberg apparently left Vienna for good. No one in the Brunsvik household knew where he had gone. He considered himself so far removed from his family obligations that he no longer fulfilled even his duties toward his two elder children, nor did he assist his wife, who was close to giving birth.
On 9 April 1813, Josephine’s presumed natural daughter by Beethoven was born. She was given the name Maria Theresia Minona Selma Arria Cornelia. The name “Minona,” taken from Goethe’s Werther, is unusual; even more striking is its anagram, “Anonim,” suggesting a deliberately concealed identity.
Mystery Within Mystery
Anyone who speculates about Beethoven’s possible paternity can only add mystery to mystery. It must be remembered that the child was born in absolute secrecy, and that only Therese von Brunsvik stood by Josephine during those sorrowful hours.
At the beginning of 1814, Christoph von Stackelberg suddenly returned to Vienna and immediately went to the police to denounce his wife, alleging a “danger to the morality of their children.” His likely intention was to force Josephine to follow him to Estonia. She refused, choosing to remain in Vienna. The authorities, believing his accusations, entrusted the couple’s three daughters to Stackelberg.
Josephine’s Collapse
It is undeniable that the severe nervous breakdown that struck Josephine was directly linked to these painful events. With a broken and powerless heart, she watched as Stackelberg took away her three young daughters. She might have wished to fight for them, but she no longer had the physical or emotional strength to resist.
While Therese cared for the children from Josephine’s first marriage to Count Joseph Deym at the Deym castle in Hacking Zinzendorf, Josephine remained in the Deym residence in Vienna, ill and devastated. In this state of profound sorrow and isolation, she refused to see anyone — not even Beethoven, one of the dearest presences in her life.
Josephine’s Death and Minona’s Fate
This tragedy shattered Josephine completely. Her suffering was indescribable, and already weakened by grief for her daughters, she died on 31 March 1821 at the age of forty‑two, officially of “exhaustion.” At that very time Beethoven was suffering from a severe attack of jaundice that brought him close to death; all work on the symphony that would become the Ninth was halted. While little Minona found refuge with her aunt Therese at the Hacking‑Hütteldorf estate, the composer entered a period marked by worsening health and the painful legal struggle over his nephew Karl — a conflict that began in 1817 and culminated in the boy’s suicide attempt in 1826.
Taken to Estonia at eighteen months, Minona saw her mother again only years later, when she was brought to Josephine’s bedside as her condition deteriorated rapidly. She was six years old when Stackelberg returned her and her siblings, Theophile and Maria Laura, to Vienna. They had barely fulfilled their filial duties before their father forced them all back to Estonia.
When Therese saw Minona again — now six years old — she immediately noticed how unlike she was to the other children Josephine had had with Stackelberg. She could not fail to see it: Minona was, after all, her “secret.” Therese wrote in her diary:
“Merkwürdig hatte sich das Kind entwickelt. Ohne schön zu sein, war sie stark und imponierte dermaßen ihren älteren Schwestern, daß wir sie immer die Gouvernante nannten. Es zeigte sich auch später, daß sie das meiste Genie unter den Schwestern hatte.” (“The child had developed in a remarkable way. Though not beautiful, she was strong and impressed her older sisters so much that we always called her the Governess. It later became clear that she had the greatest talent among the sisters.”)
Minona, Music, and the Unspoken Secret
Minona lived for some time in Tallinn, where she studied music. She became an excellent pianist and also studied composition; many of her works were published during her lifetime.
It is said that Therese von Brunsvik eventually confided the truth of the story to a nephew — long after Beethoven’s death. The nephew later reported that in 1870 Minona appealed in vain to a distant relative of her mother’s family, asking him to hand over the correspondence between Josephine and Beethoven.
Author’s Note
I have been able to locate only two works attributed to a “Mlle. Stackelberg.” A more thorough investigation is needed to determine the true extent of Minona von Stackelberg’s musical output.
The two surviving Ecossaises are conventional pieces. The first, for solo piano in E‑flat major, is a lively, typical example of the genre. The second, in the unusual key of B‑flat minor, also bears the title Ecossaise and was published by Kühnel in Leipzig. It appears, however, to have been arranged by Friedrich Heinrich Himmel (1765–1814).
Thus, although attributed to a “Mlle. Stackelberg,” this work cannot be by Minona, born in 1813 — unless one assumes an extraordinarily precocious genius.
The Lost Letters and Minona’s Legacy
The letters Minona sought throughout her life remain untraceable. They seem to lie buried in a vast family archive, only recently made partially accessible to scholars. Lacking direct documents, Minona had to rely on vague recollections and on her aunt Therese’s diary when trying to uncover her origins.
From the few portraits and rare photographs that survive, Minona appears as a strong‑willed woman, bearing — especially in old age — a striking resemblance to the master from Bonn. Like her presumed father, she lived her entire life alone. The same fate befell her Deym half‑sisters Victoire and Sophie, and her Stackelberg half‑siblings Theophile and Laura Marie.
After the death of her stepfather in 1841, Minona returned to Vienna, settling in the still‑standing Palais Cavriani in the former Oberen Bräunergasse, now Habsburgergasse No. 5. She formed a close friendship with the owner, Count Luigi Cavriani (1758–1839), and his wife, both passionate music lovers, as were the Count and Countess de Bánffy, their intimate friends.
Minona’s proud temperament — perhaps inherited from her illustrious parent — manifested itself throughout her life. When the family’s financial situation later became precarious, she would often say:
“Das bin ich meiner Herkunft schuldig!” (“My only fault is what I have inherited.”)
