John Amos Comenius, was a Czech philosopher, pedagogue and theologist. He served as the last bishop of Unity of the Brethren and became a religious refugee and one of the earliest champions of universal education, a concept eventually set forth in his book Didactica Magna. He is considered the father of modern education.

Comenius was the innovator who first introduced pictorial textbooks, written in native language instead of Latin, applied effective teaching based on the natural gradual growth from simple to more comprehensive concepts, supported lifelong learning and development of logical thinking by moving from dull memorization, presented and supported the idea of equal opportunity for impoverished children, opened doors to education for women, made instruction universal and practical.
