Bacon was the first alternative candidate suggested as the author of Shakespeare's plays. The theory was first put forth in the mid-nineteenth century, based on perceived correspondences between the philosophical ideas found in Bacon’s writings and the works of Shakespeare. Later, proponents claimed to have found legal and autobiographical allusions and cryptographic ciphers and codes in the plays and poems to buttress the theory. All academic Shakespeare scholars but a few reject the arguments for Baconian authorship, as well as those for all other alternative authors.
