During the first years of the Museum's history, there were some important donations of other collections, usually a mixture of various kinds of objects. They included not only remains of the animals (most frequently - insects, shells, birds, mammals), but also minerals and even coins and artifacts. Among most famous donators of those times was Emperor Alexander I who purchased for the Museum pretty big so called “Semyatichi Cabinet of Natural History” owned by Prince Jablonovskys family. A collection of fishes and amphibians presented to the Museum by Count A. Stroganoff is also worthy being mentioned. Besides those noble persons, the Museum from the vary beginning used to acquire important collections from prominent travelers such as G. Langsdorff and I. Eschscholz.
