Walbeck was born in Turku (Åbo). In 1817, he was made a corresponding member of the Royal Swedish Academy of Sciences and, in 1820, of the Royal Astronomical Society and the Mathematische Gesellschaft in Hamburg. He committed suicide in 1822, also in Åbo. The asteroid 1695 Walbeck is named after him. References External links Finnish Geodetic Institute.
