Joseph Jean Baptiste Neuberg

Joseph Jean Baptiste Neuberg (born October 30, 1840 in Luxembourg City , † March 22, 1926 in Liège ) was a Luxembourg-Belgian mathematician.

Neuberg attended the Athenée in Luxembourg and studied from 1859 to 1862 at the University of Ghent . Then he was a teacher in Nivelle (École Normale), from 1865 in Arlon (Athénée Royal), 1868 to 1878 in Bruges (École Normale) and 1878 to 1884 in Liège (Athénée Royal). From 1884 he was associate professor and from 1887 full professor of mathematics at the University of Liège. In 1910 he retired. In 1866 he took Belgian citizenship. He became a member of the Royal Belgian Academy of Sciences and was its president in 1911.

Together with Émile Lemoine and Henri Brocard, he is considered to be the driving force behind a revival of elementary triangular geometry at the end of the 19th century. Much of this work was published in the journal Nouvelle correspondance mathématique founded by Neuberg, Eugène Catalan and Paul Mansion (1844-1919) in 1874 and its successor (from 1881) Mathesis.

He was a member of the scientific societies of Luxembourg, Liège and the Dutch mathematical society.

Some geometric terms such as mediator (plane through the middle and perpendicular to a line segment) and bimedian (line segments between the centers of opposite sides of a square) come from him.
