30830 Jahn           Discovered 1990 Oct. 14 by F. Borngen and L. D. Schmadel at Tautenburg.
Friedrich Ludwig Jahn (1778-1852) was an educator, writer and the "father of gymnastics". He opened the first sports ground in Berlin in 1811 and founded the Turnverein (gym club) movement in Germany. He invented diverse apparatus that became standard equipment for sports activities.
