joined again in Belém and returned by ship to Rio de Janeiro, arriving on 13 March 1829, almost three years and 6,000 km after its departure. Huge scientific collections were deposited into Kunstkamera and later formed basis for South American collections of Russian museums. However, the rich scientific records of the expedition, comprising many descriptions and discoveries in zoology, botany, mineralogy, medicine, linguistics and ethnography, that were sent to Saint Petersburg by the expedition, were not published and were lost in the archives for a century. They were found again by Soviet researchers in funds of the USSR Academy of Sciences archive in 1930. Due to the travel's hardships, Langsdorff team was unable to collect many biological specimens or study them in detail, so most of their account is geographic and ethnographic, being particularly interesting on the many indigenous people of Brazil they met, many of which became extinct. Today, a large part of the material has been recovered and is in the Ethographic Museum, the Zoological Museum and in the repositories of the Academy of Sciences of St. Petersburg. Langsdorff returned to Europe shortly after the Langsdorff Expedition to the Amazon, and died in Freiburg, Germany, of typhus, in 1852. A recent study found that Langsdorff has 1,500 descendants in Brazil, among them the most famous is Luma de Oliveira, a Brazilian carnival queen. Legacy A species of venomous South American coral snake, Micrurus langsdorffi, is named in his honor. Media A film documentary, featuring Adriana Florence, a great-great-granddaughter of Hércules Florence living in Campinas, Brazil, has been made by the Discovery Channel and retraces part of the expedition's itinerary. It also visited St. Petersburg's Langsdorff museum collections. The director was Mauricio Dias.
