August Ferdinand Mobius
The German mathematician and astronomer
August Ferdinand Mobius is best known for his work in topology, expecially
for his conception of the one-sided figure now known as the Mobius strip.
He became professor of astronomy and higher
mechanics at the University of Leipzig in 1816 and director of its
observatory in 1848.
Mobius's mathematical publications, although
not always original, were effective and clear presentations.
His 1827 work on analytical geometry became a
classic. Mobius also wrote on celestial mechanics.
