Biography

After having been an assistant at the University of Vienna, Jan obtained the post of professor of botany at the university of Parma as well as becoming Director of the botanical garden. At that time, the duchy of Parma was no longer under Austrian jurisdiction following the Congress of Vienna after the defeat of Napoleon at Waterloo.

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 Ferdinando Sordelli (1837–1916), artist and naturalist, who then illustrated his publications.

Jan’s main interest was botany, but he made immense collections of natural history, including fossils and minerals. 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[1] 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 ).[2][3] 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.

The Museo Civico di Storia Naturale di Milano (Milan Natural History Museum) is a museum in Milan, Italy. It was founded in 1838 when

The Museum is located within a 19th-century building in the Indro Montanelli Garden, near the historic city gate of Porta Venezia. The structure was built between 1888 and 1893 in Neo-Romanesque style with Gothic elements.

The museum is divided into five different permanent sections: Mineralogy (with a large collection of minerals from all over the world); Paleontology (with several fossils of dinosaurs and other prehistoric organisms); Natural History of Man (dedicated to the origins and evolution of humans with a particular attention to the relationship of the latter with the environment); Invertebrate Zoology (dedicated to mollusks, arthropods and entomology); and Vertebrate Zoology (dedicated to vertebrates, both exotic and European).

The museum also exhibits the largest Italian collection of full size dioramas (over 100) that allow visitors to observe some peculiar aspects of various ecosystems.
