ASCII Character ∩
IntersectionThe symbol U+2229 ∩ was first used by Hermann Grassmann in Die Ausdehnungslehre von 1844 as general operation symbol, not specialized for intersection. From there, it was used by Giuseppe Peano (1858-1932) for intersection, in 1888 in Calcolo geometrico secondo l'Ausdehnungslehre di H. Grassmann. Peano also created the large symbols for general intersection and union of more than two classes in his 1908 book Formulario mathematico.
