Maria Theresa, Gerard van Swieten and the Birth of Modern Pathology at the Habsburg Court

The Silent Illness of Palaces

For the true irony of history lies here: the autopsy that could not be performed on Maria Theresa's own body had, as the result of a decree signed during her reign, become mandatory for every hospital death in Austria. In other words, the empress's approach to government had opened her own taboo to the public, subjected public life to science and presented it as an example to the world. This contradiction is one of the most vivid depictions of the Enlightenment's internal conflict with the court. As a result of that contradiction, 65 years after her death, the groundwork was laid for Carl von Rokitansky to perform thirty thousand autopsies at Vienna General Hospital — the greatest center of cancer pathology in the 19th century was born there.

From the Pragmatic Sanction to a Forty-Year Reign

Maria Theresa was born on 13 May 1717 at the Hofburg Palace in Vienna, the capital of the Habsburg dynasty. Her father, Holy Roman Emperor Charles VI, had no son and, through decades of diplomatic effort, persuaded the European states to accept the Pragmatische Sanktion (Pragmatic Sanction, 1713), which would allow the throne to pass to a woman. This legal maneuver opened the path to the throne for Maria Theresa while she was still a child. When her father suddenly died on 20 October 1740, the 23-year-old woman took charge of the Habsburg lands and a vast empire extending across Hungary, Bohemia, Austria, the Netherlands, Lombardy and Tuscany.

Immediately after her accession, King Frederick the Great of Prussia refused to recognize the Pragmatic Sanction and invaded Silesia — the beginning of the War of the Austrian Succession (1740-1748). Maria Theresa waged this war, gave birth to 16 children during her marriage (six died before reaching 17) and carried out fundamental reforms of the empire's finances, army, education and healthcare system. In 1745, her husband, Francis Stephen, was elected Holy Roman Emperor (meaning Maria Theresa held the title “Empress” through her husband; on her own thrones she was the sovereign — a pragmatic arrangement). When Francis died suddenly in 1765, Maria Theresa dressed in black and continued to mourn for 15 years until her death. Her son Joseph II became co-ruler with her, but the principal authority always remained with his mother.

After her death, King Frederick the Great of Prussia — her rival, whom she had faced in three wars over the years — said of her: “She honored her throne and her sex; although I fought against her, I never regarded her as an enemy.” These are among the most respectful words recorded in history between two rival sovereigns of 18th-century Europe.

Gerard van Swieten: The Physician Who Brought the Enlightenment into the Court

The transformative figure in Maria Theresa's medical decisions was not a Habsburg, but a Dutchman. Gerard van Swieten (1700-1772) trained at Leiden University, which stood at the pinnacle of 18th-century European medicine, and had been the closest student of Hermann Boerhaave (1668-1738) for many years. Boerhaave was the most famous physician of his time; he introduced “bedside teaching” into clinical medicine and is the intellectual forefather of modern medical education. Van Swieten had both adopted his method and rewritten it in his own words.

In 1745, Maria Theresa brought van Swieten from the Netherlands to Vienna as her personal physician. There was a political reason for this: the local physicians of the Habsburg court (most still rooted in the Galenic tradition of half a century earlier) were backward in the empress's eyes. Van Swieten was the man who would bring Boerhaave's Enlightenment clinic to the Habsburg court. After arriving, he did three things:

First, he served the empress as chief physician . When Maria Theresa contracted smallpox in 1767, he was the physician who contributed most to her survival. Second, he directed the reform of the University of Vienna's Faculty of Medicine: a new curriculum, clinical training, bedside teaching and a modern library. As a result of this reform, Vienna became one of Europe's centers of medical education in the second half of the 18th century. Third, and most importantly for the history of oncology, he persuaded Maria Theresa to sign a decree in 1761 — the year Morgagni's De Sedibus was published.

The irony is this: the institutional change initiated by van Swieten could never be applied to the body of the empress whom he personally served. Under court etiquette, the sovereign's body was sacred; cutting it open — especially the empress's body — was unthinkable. Yet, for the rest of the country, Europe's most comprehensive autopsy decree bore her signature. The court's enlightenment took place on a street outside the court.

From the Smallpox Nightmare of 1767 to November 1780

Maria Theresa's medical history reached a sharp turning point in 1767. That year, two members of her family at the Habsburg court — her daughter-in-law, Empress Maria Josepha, and her daughter, Maria Josepha — died of smallpox. Maria Theresa contracted it herself. She survived, but the court physicians described it as “something very close to a miracle.” After that illness, the empress gained weight rapidly, dyspnea (shortness of breath) became pronounced and her former energy was replaced by constant fatigue. This was a marked physical decline for a woman of only 50.

During the thirteen years between 1767 and 1780, Maria Theresa lived with a chronic respiratory illness. The most frequently repeated phrases in the court records were “catarrhal cold", "mucus accumulation in the lungs", "productive cough", "a sensation of suffocation when lying down (orthopnea).” From a contemporary perspective, the most likely explanation of this picture is a combination of chronic bronchitis and obesity-related right heart failure; however, the possibilities of pulmonary tuberculosis or — less likely, but not excludable — a primary lung malignancy also arise occasionally in contemporary paleopathological discussion.

On the morning of Wednesday, 29 November 1780, Maria Theresa died at Schönbrunn Palace at 63. Court physician Anton von Störck (himself van Swieten's student, who had become chief court physician after his death) recorded “obstruction arising from the lungs and heart failure” on the death certificate. No autopsy was performed. Her body was placed in the coffin in the Imperial Crypt of the Capuchin Church (Kapuzinergruft) — beside her husband, Francis Stephen, in the tomb on which she had arranged for her own epitaph to be inscribed during her lifetime.

The Ghost of a 244-Year Medical Secret

The three possibilities most often put forward in modern paleopathological literature as the cause of Maria Theresa's death are:

• Chronic obstructive pulmonary disease (COPD) + obesity + right heart failure: In the 18th-century Viennese court, coal was burned for central heating, filling rooms with smoke and soot; in addition, Maria Theresa lived with excess weight for years, and candles were a significant source of pollution in enclosed palace apartments. The combination of these three factors is consistent with modern COPD and cor pulmonale (right heart failure). This is the consensus view.
• Pulmonary tuberculosis: In the 18th century, much of Europe's population had latent infection with the tuberculosis bacillus. Even the court environment could not escape this infection (her son Joseph II would die of probable tuberculosis 10 years later). Maria Theresa's long-standing productive cough and the tendency toward weight loss that became more apparent in her final months could be consistent with tuberculosis.
• Primary lung cancer: Low probability. She did not use tobacco (royal women did not take snuff); however, coal smoke and candle soot in indoor air are associated with a slight increase in lung cancer risk in modern epidemiological studies. The combination of “edema,” “suffocation” and “severe cough” in the court records could be interpreted as a paraneoplastic presentation. But without an autopsy, this diagnosis cannot be confirmed.

From the perspective of cancer history, none of these three possibilities is certain. What matters is this: the diagnosis has remained uncertain because no autopsy was performed. This uncertainty is a structural feature of court medicine in that era — the sovereign's body was shielded from pathological examination for political reasons, making courts “black holes” of medical knowledge for centuries. While public hospitals supplied science with data through routine autopsies, courts kept their doors closed.

Lady Mary Montagu, Maria Theresa and the Inoculation That Came from Istanbul

Here we build a bridge that connects to the series' long chain and is particularly meaningful for Turkish readers. After Maria Theresa survived smallpox in 1767, grieving the losses in her family, she asked van Swieten: “Is there a way to prevent this disease?” Van Swieten answered that there was, and that the answer came from the Ottoman Empire .

Variolation — the method of taking a small amount from a smallpox patient's purulent scab and transferring it to a healthy person to produce a mild infection and confer immunity — originated in China in the 16th century and spread westward through India and Anatolia. In early 18th-century Istanbul, it was widely practiced in folk medicine within Greek and Armenian medical traditions. Lady Mary Wortley Montagu, the wife of Britain's ambassador to the Ottoman Empire in Istanbul in 1717-1718, learned this practice from Turkish physicians and midwives and had it performed on her son; she then introduced it to Europe after returning to London. The first trials in Britain took place in 1721; by the 1740s, the practice had spread controversially across Europe.

In 1768 — exactly 50 years after Lady Montagu's observations in Istanbul — Maria Theresa permitted the children of the Habsburg court to undergo variolation by the Dutch physician Jan Ingen-Housz . This marked the beginning of the first state-supported inoculation program in the Austrian Empire. Over the next ten years, thousands of children in Habsburg territories were inoculated by variolation; smallpox mortality fell dramatically. This practice is the direct predecessor of modern vaccination — 30 years later, Edward Jenner's vaccination using cowpox (vaccinia) would develop as a safer version of variolation.

The meaning of this bridge: China → India → Ottoman Istanbul → Lady Montagu → Britain → Europe → the Habsburg court → the Austrian population → universal acceptance of modern vaccination. One link in this chain for today's Turkish-speaking world is this: the practical knowledge of Turkish midwives in Istanbul was one of the sources of public health reform in 18th-century Europe. Maria Theresa's decision in 1768 was one of the first moments when that practical knowledge became European state policy.

From the Autopsy Decree of 1761 to Rokitansky's 30.000 Cases

When Maria Theresa died in 1780, her decree of 1761 had not yet shown its full impact — autopsy practice was becoming established in the Austrian Empire's hospitals, but it was still in the accumulation phase. Accumulation truly began during the reign of her son Joseph II (1780-1790), with the opening of the Allgemeines Krankenhaus (Vienna General Hospital): 16 August 1784, the largest general hospital the world had yet seen, with 2.000 beds, systematic clinical records and mandatory autopsy procedures. The son institutionalized what the mother had begun.

Over the next half-century, Vienna became the center of European pathological anatomy. Carl von Rokitansky (1804-1878) worked for thirty-one years, from 1844 to 1875, at the pathology institute of Vienna General Hospital; he is reported to have performed thirty thousand autopsies and personally supervised more than seventy thousand. His three-volume work, published in 1842-1846, Handbuch der pathologischen Anatomie , formed the backbone of 19th-century pathology literature. Its importance for cancer is immense: systematic macroscopic descriptions of tumors of the stomach, lung, breast, prostate, liver, kidney, brain and lymphatic system, maps of their anatomical distribution, patterns of metastasis and clinical correlations — all accumulated in Rokitansky's notes.

Famous figures who worked or trained in Rokitansky's Vienna included Josef Skoda (one of the founders of percussion and auscultation), Ignaz Semmelweis (who would discover here in the 1840s the effect of handwashing on puerperal fever — Day 85 of the series), Ferdinand von Hebra (the father of modern dermatology) and, indirectly, Rudolf Virchow (who learned from the Vienna school's methods despite working in Berlin). In other words, a generation of the most crucial figures in 19th-century European medicine emerged as an extension of Maria Theresa's decree of 1761.

Mother and Daughter: Two Tragedies, Two Histories

When Maria Theresa died on 29 November 1780, her youngest daughter, Marie Antoinette, was 25, lived at Versailles, had given birth to three children and sat as Queen of France at the heart of a monarchy that would fall a century later. The final letter between mother and daughter was written two weeks before the death; in it, Maria Theresa spoke of difficulty breathing, loneliness and the exhaustion of the 15 years since her husband's death.

Maria Theresa did not witness the French Revolution — the Bastille would fall 9 years after her death (14 July 1789), and Marie Antoinette would be executed by guillotine 13 years later (16 October 1793). The mother's biological illness is uncertain; the daughter's political end is definite. Sent to Versailles at 14 as part of the diplomatic calculations of the Habsburg–Bourbon marriage, this child died at 37 in Paris's Place de la Révolution, 13 years after her mother's death.

The bridge between the stories of mother and daughter is also meaningful for the history of oncology: the bodily health of women at 18th-century courts was the sphere in which the era's medical limitations were most rigidly enforced. Maria Theresa's illness was not documented, autopsied or put into words. During Marie Antoinette's months in the Conciergerie after her arrest, findings interpreted by some modern historians as “vaginal bleeding, anemia and physical collapse” were likewise not recorded, because, as a political prisoner, she was no longer granted access to a physician. These two royal women, one in a palace and the other in a prison, fell at opposite ends of the era's medical limitations. This parallel is another facet of the “problem of undocumented royal illness” in cancer history.

This article is Day 70 of the Cancer History in 365 Days Series; it is also a thematic feature on 18th-century court medicine and the institutional establishment of modern pathology. The birth of the 19th-century Vienna School of Pathology as an extension of Maria Theresa's decree of 1761, Rokitansky and the subsequent generation of Virchow will be explored on Days 87 and 88 of the series. Tomorrow, Day 71, continues with Frances Burney's letter about her Paris mastectomy in 1811 — an example of the transition from courtly silence to public testimony. The article is written from a popular historical perspective; it contains no guidance on medical treatment.
