William Camden (kăm´dən), 1551–1623, English scholar, chief historian and antiquary of Elizabethan times. His two chief works are Britannia (1586) and Annales rerum Anglicarum et Hibernicarum regnante Elizabetha [annals of affairs in England and Ireland in the reign of Elizabeth]. He was a conscientious scholar in editing old manuscripts and in collecting materials of antiquarian interest. He was also a teacher (1575–97) and headmaster (1593–97) at Westminster School and helped to revive the study of Anglo-Saxon. He wrote a Greek grammar long popular in English secondary schools and aided Sir Robert Cotton in collecting materials.
