August Ferdinand Möbius

August Ferdinand Möbius (November 17, 1790, Schulpforta, Saxony, Germany - September 26, 1868, Leipzig) was a German mathematician and theoretical astronomer.

He is best known for his discovery of the Möbius strip, a non-orientable two-dimensional surface with only one side when immersed in three-dimensional Euclidean space. It was independently discovered by Johann Benedict Listing at about the same time. Möbius was the first to introduce homogeneous coordinates into projective geometry. Möbius transformations;, important in projective geometry, and not to be confused with the Möbius transform; of number theory, also bear his name. His interest was also in number theory, and the important Möbius function μ(n) and the Möbius inversion formula; are named after him.

He was a descendant of Martin Luther.
