Frequently asked questions

Camillo Golgi was an Italian physician and biologist born in 1843, a pioneer in the study of the nervous system. What makes him famous is that in 1873 he developed the “black reaction,” a silver-nitrate staining technique that, for the first time, allowed nerve cells to be seen in their entirety. Imagine a microscope that, until then, showed only grey smudges: his method revealed the entire branching structure of neurons. He also discovered the Golgi apparatus in 1898, an essential organelle present in almost all of our cells, and he received the Nobel Prize in Medicine in 1906.

Key Facts

  • Born in 1843 in Corteno (today Corteno Golgi), Italy
  • Developed the “black reaction” in 1873, a method of staining nerve cells with silver nitrate
  • Described the Golgi apparatus, a cellular organelle, in 1898
  • Received the 1906 Nobel Prize in Physiology or Medicine, shared with Santiago Ramón y Cajal
  • Died in 1926 in Pavia

Works & Achievements

The black reaction (Golgi's method) (1873)

A silver nitrate staining technique that makes entire nerve cells visible. It laid the foundations of modern neuroanatomy and is still used today.

Description of Golgi cells (1873-1875)

Golgi distinguished two main types of neurons according to the length of their projection; some neurons still bear his name.

Golgi's law on malaria (1886)

Demonstration that fever attacks coincide with the multiplication and release of parasites into the blood, a major step in understanding the disease.

Discovery of the Golgi apparatus (1898)

Identification of an internal organelle of the cell, present in almost all cells and essential to the sorting of proteins; it bears his name.

Description of the Golgi tendon organs (1880)

Identification of sensory receptors located in the tendons, which inform the brain of muscle tension.

Nobel Prize in Physiology or Medicine (1906)

Award given jointly to Golgi and Cajal “in recognition of their work on the structure of the nervous system.”

Anecdotes

In 1873, Camillo Golgi developed his famous “black reaction” almost by chance, in the kitchen of a small hospital for the incurable where he worked, for lack of a laboratory. By impregnating fragments of brain with silver nitrate, he obtained nerve cells entirely blackened against a yellow background, finally visible in all their detail.

In 1906, Golgi shared the Nobel Prize in Medicine with the Spaniard Santiago Ramón y Cajal, who had nonetheless used his own staining method. The paradox was complete: the two men scientifically detested each other, for Golgi believed that the nervous system formed a continuous network, whereas Cajal defended the idea that neurons are separate cells — and it was Cajal who was right.

During his Nobel acceptance speech in Stockholm, Golgi used the platform to openly attack the neuron theory defended by Cajal, who was seated in the very same room. It was one of the most tense moments in the history of the scientific Nobel Prizes.

While studying malaria, Golgi discovered that the bouts of fever coincided with the moment when the parasites multiply and burst in the blood: this is “Golgi's law.” This observation made it possible to better understand and treat the disease.

In 1898, while observing stained nerve cells, Golgi described a network of tiny filaments inside the cell. This “Golgi apparatus” still bears his name today and appears in every biology textbook: it is an essential organelle present in almost all of our cells.

I have obtained magnificent results with a method that seems to me destined for a great future, by letting potassium bichromate act at length, then silver nitrate, on hardened fragments of the brain.
Nobel Prize Lecture: The Neuron Doctrine — Theory and Facts (Nobel Lecture) (11 December 1906)
Although the neuron doctrine is fashionable today, I do not believe I can regard it as definitively established; the facts I have observed lead me, on the contrary, to accept the continuity of the nervous network.
On the internal reticular apparatus of nerve cells (1898)
Within the cell body a fine reticular apparatus is revealed, stained black by the silver impregnation, whose arrangement deserves the greatest attention.
Studies on the developmental cycle of the malaria parasites in tertian fever (1886)
The febrile attack corresponds with remarkable regularity to the moment of segmentation and release of the parasites into the patient's blood.
