15766 Strahlenberg           Discovered 1993 Jan. 22 by E. W. Elst at the European Southern Observatory.
Philip Johan von Strahlenberg (1676-1747), a Swedish officer and geographer, was kept prisoner in 1709 at Poltawa and during 1711-1721 sent to Tobolsk, where he investigated the geography and nature of Siberia. He also studied the languages of the Tatars and Mongols.
