An algebraic surface of the fourth order and class, reciprocal to itself, having 16 double points, of which 16 groups (each containing 6 points) are situated in one double tangent to the surface (i.e. a plane which is tangent to the surface along a conic section). The equation of degree 16 defining the double element yields a single equation of degree 6 and several quadratic equations. Discovered by E. Kummer (1864). The Kummer surface is a special kind of $K3$-surface; it is determined within the class of $K3$-surfaces by the condition that it contains 16 irreducible rational curves.

Comments
A quartic surface in $P^3$ has at most 16 double points (as has the Kummer surface).
From a modern point of view, Kummer surfaces are obtained by taking a $2$-torus $T$, taking the involution $\sigma$ on $T$ defined by $\sigma(x)=-x$, taking the quotient of $T$ divided out by this involution, and resolving the sixteen double points of this surface.
