Heinrich Quincke

Heinrich Irenaeus Quincke (1842-1922) portrait

Heinrich Irenaeus Quincke (1842-1922) was a German physician.

Quincke was a prolific medical investigator whose contributions to clinical medicine and physiology spanned five decades. He studied medicine in Berlin, Heidelberg, and Würzburg under luminaries such as Rudolf Virchow, Albert von Kölliker, and Hermann von Helmholtz. He earned his doctorate in 1863 and later worked as an assistant at the Charité Hospital in Berlin under Friedrich Theodor von Frerichs, where his early research focused on cerebrospinal fluid dynamics.

Quincke is best known for several eponymous clinical signs and syndromes. His 1868 description of the capillary pulse (Quincke’s pulse) remains a classic finding in aortic insufficiency. In 1882, he published the first detailed account of acute circumscribed oedema (Quincke’s oedema). In 1891 he introduced the lumbar puncture (Quincke’s puncture) at the Congress of Internal Medicine in Wiesbaden, marking a major advance in neurological diagnosis and treatment. He also identified the fungal agent later named Trichophyton quinckeanum in 1886, and in 1871 described the triad of haemobilia: jaundice, right upper quadrant pain, and gastrointestinal bleeding (Quincke’s triad).

Beyond his eponymous achievements, Quincke contributed foundational work across numerous domains: poikilocytosis in pernicious anaemia, haemolysis, caisson disease, nephritic oedema, diabetic coma, and gastrointestinal therapeutics. He co-authored seminal texts on pulmonary surgery and liver disease and served as Professor of Medicine at the universities of Bern and Kiel, where he trained generations of clinicians. Though nominated for the Nobel Prize in 1909 and again unanimously recommended in 1918, he was ultimately denied the honour.

Quincke retired in 1908 and remained active in Frankfurt until his death in 1922. A polymath, mentor, and meticulous observer, his work continues to resonate in modern clinical practice.

Medical Eponyms
Quincke’s pulse (1868)

An alternate paling and flushing of the skin at the root of the nail while pressure is applied to the tip of the nail, classically observed in patients with aortic regurgitation.

In 1868, at just 26 years of age, Heinrich Quincke published his observations on capillary and venous pulsations while working as an assistant at the Medical Clinic in Berlin. He described the capillary pulse as a visible, rhythmic change in nailbed coloration, best seen at the junction between the pale lunula and the pink nailbed.

As far as the capillary pulse is concerned, so can one see it best on his own finger nail, or better, on that of another, in the area between the whitish, blood-poor area and the red injected part of the capillary system of the nail-bed; in the majority of persons examined, there is, with each heartbeat, a forward and backward movement of the margin between the red and white part..

Quincke 1868

He noted that while this sign can be observed in many healthy individuals, it becomes particularly conspicuous in cases of aortic insufficiency due to the bounding, high-volume pulse:

A large and rapidly falling pulse is seen especially in aortic insufficiency, and for this reason the capillary pulse is especially clear in this condition.

Quincke’s triad (1871)

Triad of right upper quadrant pain, jaundice, and upper gastrointestinal bleeding indicative of hemobilia (bleeding into the biliary tract)

In 1871, Quincke published a detailed case of hepatic artery aneurysm rupture leading to bleeding into the biliary tree in Ein fall von Aneurysma der Leberarterie. He described the three cardinal features now recognised as Quincke’s triad.

Die Krankheit begann…mit Kolik, Erbrechen und etwas Blutbeimengung im Stuhl… Der Kranke war bleich, hatte leichten Ikterus… gegen Abend Bluterbrechen…Wiederholte Blutungen aus dem Magen und schwarzer Stuhl wechselten mit Gelbsucht und Schmerzanfällen im rechten Hypochondrium – Quincke 1871

The illness began…with colic, vomiting and some blood in the stool…The patient was pale, had slight jaundice…in the evening he vomited blood…Repeated bleeding from the stomach and black stools alternated with jaundice and attacks of pain in the right hypochondrium – Quincke 1871


Quincke’s oedema (1882)

Also known as angioneurotic oedema or Quincke’s disease, this condition presents as sudden, transient, non-pitting oedematous swellings of the skin and subcutaneous tissues—most commonly affecting the lips, eyelids, face, extremities, and gastrointestinal mucosa.

Although Heinrich Quincke formally described the condition in 1882, earlier mentions had been made by Robert James Graves (1796-1853) in 1843 (as “fugitive inflammation”) and John Laws Milton (1820–1898) in 1876, who used the term “giant urticaria.”

I wish to identify a skin disease which does not seem to be rare; however, only a few cases of it have been described. This disease appears as oedematous swelling of the skin and the subcutaneous tissue in localized lesions from 2 to 10 cm. or more in diameter… Particularly on the lips and eyelids… Localized swellings also appear in the gastrointestinal mucosa producing symptoms… Because of its manner of development, acute localized swelling of the skin and mucous membranes, it should be considered as an angioneurosis

Quincke 1882

The lesions are often painless, without itching, and typically resolve within hours to days. In modern medicine, hereditary forms of this condition are linked to C1 esterase inhibitor deficiency and excessive bradykinin production.


Quincke’s puncture (1891)

The introduction of lumbar puncture as a diagnostic and therapeutic method for withdrawing cerebrospinal fluid (CSF) was one of Quincke’s most impactful contributions to medicine.

Quincke studied CSF physiology in dogs including the communication between the cerebral and spinal subarachnoid spaces. He hypothesized that withdrawing CSF might relieve pressure in children with hydrocephalus. He first presented the method publicly at the Congress of Internal Medicine in Wiesbaden in April 1891.

The fluid was withdrawn via a fine needle between the third and fourth lumbar vertebrae… with the help of a stylet. Pressure readings were taken before and after drainage… and samples analysed for protein, sugar, cells, and bacteria.

Quincke 1891

He performed his first lumbar puncture in 1888 on a 12-year-old boy with hydrocephalus. Unfortunately the child died despite six procedures. In 1890, he treated a 21-month-old child with suspected tuberculous meningitis who recovered after three lumbar punctures. His third case, a 25-year-old man with chronic hydrocephalus and severe headaches, improved after the procedure.

Quincke’s landmark publication, Die lumbalpunction des hydrocephalus (1891), described lumbar puncture in ten patients (five children and five adults) and detailed both technique and early diagnostic value.

Although met with initial skepticism, his method became a cornerstone of neurological investigation and CSF sampling. The classic Quincke spinal needle (Kanülen, nach Quincke), with its A-bevel cutting tip and Luer lock hub, remains in use today.


Achorion of Quincke (1886)

Quincke described the α-Pilz (“alpha fungus”) dermatophyte in 1886 as the causative agent of mouse favus. It is now taxonomically recognised as Trichophyton quinckeanum.

In Über Favuspilze (1886), Quincke reported several cases of superficial fungal infections acquired from mice, including a young girl who developed facial lesions after playing in a stable. From both human and mouse specimens, he cultivated and described the causative organism:

The α-Pilz is distinguished by its pointed spores… a species found on the skin of infected mice and transmissible to humans.

Quincke 1886

Favus caused by this organism is rare but notable for its zoonotic origin and characteristic “mousy” odour. Taxonomists reclassified Quincke’s α-Pilz as Trichophyton quinckeanum, placing it among the dermatophytes distinct from T. mentagrophytes. Cultures typically display a white, crateriform growth with reduced micromorphology and pyriform microconidia.

Recent morphological studies confirm the unique features of T. quinckeanum, including:

  • Filiform appendages on macroconidia
  • Absence of spiral hyphae
  • Varieties adapted specifically to white or grey mice
  • High CO₂ culture promoting “star-like” growth patterns and sporulation

Quincke’s discovery marked one of the earliest documented cases of direct animal-to-human mycotic transmission and remains a cornerstone in medical mycology.


Key Medical Attributions
Mallory-Weiss Syndrome (1879)

The eponymous term refers to George Kenneth Mallory and Soma Weiss and their 1929 description of postemetic lacerations at the gastroesophageal junction.

Quincke, then in Kiel, published Ulcus oesophagi ex digestione. He described three cases of oesophageal ulceration in the distal oesophagus, unrelated to carcinoma, corrosives, or trauma. Two patients died of massive haematemesis, one developed perforation into the pleura, and another had cicatricial stricture.

Quincke proposed the term ulcus ex digestione to describe an ulcer caused by the action of gastric juice upon the oesophageal mucosa, analogous to simple gastric ulcer. This was an early demonstration of oesophageal ulcer as a primary lesion and the first to connect it to fatal haematemesis.

Die beschriebenen drei Fälle zeigen… dass im unteren Theil der Speiseröhre Geschwüre vorkommen… die durch die verdauende Einwirkung des Magensaftes entstanden sind… und daher mit dem sogenannten einfachen Magengeschwür auf eine Linie gestellt werden müssen – Quincke 1879

The three cases described show… that ulcers do occur in the lower part of the oesophagus… arising from the digestive action of gastric juice… and must therefore be placed on the same line as the so-called simple gastric ulcer – Quincke 1879


Scientific Contributions

Beyond his eponymous legacy, Heinrich Quincke’s scientific pursuits spanned multiple disciplines, reflecting a deep curiosity and a meticulous clinical approach. He conducted pioneering investigations into poikilocytosis and haemolysis of erythrocytes, contributing early insights into the haematologic abnormalities of pernicious anaemia and the mechanisms of haemosiderosis. His experimental work on caisson disease offered some of the first physiological explanations for decompression sickness.

In internal medicine, Quincke studied the extrarenal mechanisms of nephritic oedema, emphasizing vascular permeability rather than purely renal causes, well ahead of its time. He investigated the role of iron salts in therapy, advanced understanding of gastrointestinal nutrition in illness, and described diabetic coma with clinical precision. His surgical collaborations produced one of the earliest treatises on pulmonary abscess management.

Quincke also published on infectious diseases, including amoebic dysentery, typhoid fever, and the utility of lumbar puncture in the diagnosis of tuberculous meningitis—further underscoring the diagnostic value of his CSF studies. His breadth of publications, blending physiology, pathology, and therapeutics, helped shape internal medicine in the late 19th and early 20th centuries.


Controversies
Not…The Nobel Prize

Quincke was nominated for the 1909 Nobel Prize in Physiology or Medicine for his pioneering work on lumbar puncture (first presented in 1891). However, the committee rejected the nomination, citing the 18-year delay between discovery and recognition.

In 1918, circumstances changed. A prior critic now praised Quincke’s work as being of “extraordinarily high diagnostic value.” The Nobel Committee unanimously recommended Quincke for the prize. Yet, at 76 years of age, he was ultimately passed over again, deemed too old to receive the honour.

This decision would later echo in the case of Joseph Babinski (1857–1932), and Bernhard Naunyn (1839-1925) both falling foul of ageism.

Notably, Nobel rules evolved: in 1966, Peyton Rous (1879–1970) received the Nobel Prize at age 87, for a discovery published 55 years earlier, correcting the ageist principle that once excluded Quincke, Babinski and Naunyn.
