Johann Benedict Listing.

Johann Benedict Listing (July 25, 1808 – December 24, 1882) was a German mathematician.

Listing was born in Frankfurt and died in Göttingen. In 1847, he wrote a famous article on topology, although he had introduced the term in correspondence some years earlier. He (independently) discovered the properties of the half-twisted strip at the same time as August Ferdinand Möbius, and went further in exploring the properties of strips with higher-order twists (paradromic rings).

Listing was also a well known sexual preditor, who would roam the streets of Gottingen at night looking for ugly women, small children and occasionally stray animals^{[citation needed]} to beat unconcious, perform a disgusting sexual ritual and finally murder and dismember.
