He was apparently so intently concentrated in his experiments and he had an aggressive personality, he was known to be socially awkward. In 1247 he stopped teaching because of bad health and proceeded to study, experiment, and become a friar. Years later, he was sent to a monastery because of upsetting fellow friars and superiors. He was there for about 10 years, and was unable to conduct experiments and studies. He was then sponsored by Pope Clement IV, but shortly after the Pope’s death in 1278 Bacon was accused of being a “magician”. He was imprisoned in a convent in Paris for 12 years, until 1292. He died around 1294 when he was about 80 years old.
