Let $A\_n$ be the $n\times n$ matrix whose $(i,j)$-element is $1/(i+j-1)$. This is a famous matrix in linear algebra and has some nice properties (like, its inverse is integral).


Does anybody remember the name of this matrix? I am sure it was named after somebody but I don't remember. And I need the name for some reason.
