The superconducting proximity effect arises when a superconductor ?shares? its pairs with a nonsuperconducting layer with which it is in good contact. It has been studied in many experiments, sometimes showing unexpected behavior. Renewed interest in proximity coupled superconductivity has arisen due to experimental results that suggest Majorana Fermions can form in devices that include topological materials, such as topological insulators and devices made from certain semiconductors such as InAs. I will review superconductivity and the proximity effect, and then discuss some recent experiments in which proximity induced changes in normal state properties of both semiconductors and topological insulators have been measured.
