The discovery of the Golgi apparatus

The existence of the cell organelle which is now known as Golgi apparatus or Golgi complex, or simply as 'the Golgi", was first reported by Camillo Golgi in 1898, when he described in nerve cells an 'internal reticular apparatus' impregnated by a variant of his chromoargentic staining. It soon became clear that the newly-identified cytoplasmic structure occurred in a variety of cell types. However, the reality of the organelle was questioned for decades, until it was finally ascertained with electron microscopy. The Golgi apparatus was destined to become a protagonist of the research in cytology and cell biology pursued in the second half of the twentieth century.
