c.1214 - c.1292
English Philosopher
Roger Bacon, a Franciscan of Oxford, is regarded as the fore-runner of modern experimental science.

Roger Bacon made lists of possible inventions 300 years before Leonardo da Vinci. There he described spectacles, flying machines, motorized ships and the process for making gun powder.

His writings are a passionate tirade against ignorance. He combined his attack upon the ignorance of his time with suggestions for the increase of knowledge. But the novelty of his ideas led to his imprisonment in 1277.
