Doppelbock or double bock is a stronger version of traditional bock that was first brewed in Munich by the Paulaner Friars, a Franciscan order founded by St. Francis of Paula.
Eisbock is bock or doppelbock fortified by removing ice after partial freezing. Eisbock is said to have been serendipitously invented when a feckless brewery employee of Kulmbacher in Bavaria left a few casks of doppelbock outside during frigid weather. The liquid portion was sampled and found to be quite fetching.
