George Boole was born in 1815. He was the son of a poor merchant. He learned the material of the elementary school very quickly; his father could not afford to pay for further education. George began to study independently. At 16, he started teaching at school, and three years later, he founded his school to earn money. While working at his school, he became interested in mathematics and began writing papers in this field. At first, his work was rejected, even for lack of education, but eventually, his work was recognized and published. The English genius, mathematician and logician, developed the principles by which computers work today.
