Authors Lawrence and Nancy Goldstone make an excellent case that this manuscript was authored by Roger Bacon. The book is titled:
The Friar and the Cipher: Roger Bacon and the Unsolved Mystery of the Most Unusual Manuscript in the World; Doubleday, 2005
Bacon, an English philosopher, was a true pioneer in the scientific method. He had to avoid writing in Latin to avoid trouble with the church.
