Martynas Mažvydas
Martynas Mažvydas (1510–1563) was a Protestant writer who produced the first printed book in Lithuanian. Persecuted for his Lutheran beliefs, he entered the university in Königsberg in 1546 at Duke Albrecht of Prussia's invitation. In 1547 he and his collaborators published The Simple Words of Catechism, based on Martin Luther's Small Catechism.
From 1549 he served as priest and from 1554 as archdeacon of Ragainė, issuing further Lithuanian hymns and prayer books until his death in Königsberg in 1563.
