1504-1548. Reformed scholar. Born at Leipzig, he served as secretary at many of the theological discussions of his time, notably at Worms and Ratisbon in 1541. One of his outstanding services was to preserve in shorthand many of the lectures and sermons of Luther, with whom also he collaborated in Bible translation. In his youth Cruciger studied theology under Luther and Melanchthon and became proficient also in Hebrew, natural history, and medicine. For a few years he served as a teacher in Magdeburg, but went to Wittenberg in 1528 as preacher and professor, remaining there until his death. Beza records that after a private conference with Calvin on the doctrine of the Lord's Supper, Cruciger became attached to the Calvinist position on that question.
