Each bounded sequence of real (or complex) numbers contains a convergent subsequence. It can be generalized to include more general objects, e.g. any bounded infinite set in $n$-dimensional Euclidean space has at least one limit point in that space. There exist analogues of this theorem for even more general spaces.
The theorem was demonstrated by B. Bolzaon [Bo]; it was later also independently deduced by K. Weierstrass.
