Italian physicist Camillo Golgi had first identified the Golgi apparatus, an organelle found in most eukaryotic cells in 1897 during an investigation of the nervous system; it is named after him in 1898. 

Part of the endomembrane system in the cytoplasm, the Golgi apparatus packages proteins into membrane-bound vesicles inside the cell before the vesicles are sent to their destination.

The Golgi apparatus resides at the intersection of the secretory, lysosomal, and endocytic pathways.

It is of particular importance in processing proteins for secretion, containing a set of glycosylation enzymes that attach various sugar monomers to proteins as the proteins move through the apparatus.

After first observing it under his microscope, Golgi termed the structure as apparato reticolare interno ("internal reticular apparatus").

Some doubt the discovery at first, arguing that the appearance of the structure is merely an optical illusion created by the observation technique used by Golgi.

With the development of modern microscopes in the twentieth century, the discovery will be confirmed.

Early references to the Golgi apparatus refer to it by various names including the "Golgi–Holmgren apparatus", "Golgi–Holmgren ducts", and "Golgi–Kopsch apparatus".

The term "Golgi apparatus" will be used in 1910 and will first appear in the scientific literature in 1913, while "Golgi complex" will be introduced in 1956.
