Abstract: Let $ W$ be a Riemann surface other than the sphere, plane, punctured plane or torus. Let $ f$ be a holomorphic map of the punctured disk $ 0 < \left\vert z \right\vert < 1$ into $ W$. Then $ f$ can be extended to a holomorphic map of the disk $ \left\vert z \right\vert < 1$, possibly, into a Riemann surface $ {W^ * }$ containing $ W$. We give a new proof of this fact and explore some consequences of it.
