Freud studies under Claus and Bruecke.
In 1876 Freud works in the Institute of Comparative Anatomy and receives a research scholarship to work at the Laboratory for Marine Zoology in Trieste. There he studies the sexual organs of eels and produced his first publication on this subject but is not happy about the inconclusive results.
Drawing by Freud
The drawing of Freud's study at the zoological station in Trieste, which he sent to Eduard Silberstein in 1876.
After his return from Trieste he begins work as assistant in the Physiological Institute directed by the eminent scientist Ernst Bruecke. Here he says, "I found rest and satisfaction -- and men, too, whom I could respect and take as my models." One of these models is an older colleague and future friend Ernst von Fleischl, a physiologist who played an important role in the beginning of Freud's scientific career.

Freud develops a new method of staining microscope samples of nerve tissue and hopes to make his scientific reputation through this discovery.
In 1879 to earn some money he translates a volume of essays by John Stuart Mill for Theodor Gomperz's complete German edition of Mill's work.
His first publications include: "On the origin of the posterior nerve-roots in the spinal cord of the ammocoetes", "Observations on the configuration and finer structure of the lobed organs in eels described as testes", "Note on a method for anatomical preparation of the nervous system".
