He is also known as Georg Jan or Georges Jan.
Giuseppe de Cristoforis died in 1837 bequeathing his collections to the town of Milan on condition that the municipality created a natural history museum whose direction had to be entrusted to Giorgio Jan, who offered his own collections.
The Museo Civico di Storia Naturale di Milano was created the following year and is the oldest natural history museum of Italy.
Jan immediately engaged (1837–1916), artist and naturalist, who then illustrated his publications.
With Giuseppe de Cristoforis, he published many catalogues of specimens, often offered for sale or exchange.
In these many new species, were described mainly insects and molluscs.
In the scientific field of herpetology he is credited with having described more than 85 new species of snakes, and is honored by having several species and subspecies named after him, such as the Texas night snake (Hypsiglena torquata jani ), the Mexican pine snake (Pituophis deppei jani ), Jan's shovelsnout snake (Prosymna janii ), and Jan's centipede snake (Tantilla jani ).
In the 1860s he began compiling what was to become the Iconographie Général des Ophidiens, an extensive illustrated collection of scientific papers relating to snakes, but he died before it was completed.
The work was eventually finished and published in several parts by Sordelli.
