Abstract A summary is given of the current beliefs regarding the origin and history of the light elements 2D, 3Re, 4Re, 6Li, 7Li, 9Be, 10B, and 11B in the universe. A description of the various sites of nucleosynthesis for these elements is given, and the results compared with observations. It is found that the galactic cosmic rays (GCR) can spallogenically produce 6Li, 9Be, and 10B as well as the bulk of the 11B (perhaps all) and 10 percent of the 7Li. The deuterium can only be produced pregalactically either in the big bang or in some pregalactic event. The big bang or pregalactic events will also produce 3Re and 4Re and some 7Li. Additional 7Li (and possibly even some 11B) can be synthesized during the helium-flash stage in red giants. Stellar synthesis might also add 3Re to the galactic gas.
