Nick Pelling is a British-born computer programmer, best known for a series of 1980s computer games for the BBC Micro written under the nom-de-plume Orlando M. Pilchard. He was educated at Brentwood School, and has both a BSc in Maths and Philosophy (from Manchester University) and an MBA with Distinction (from Kingston University). He is a leading Voynich Manuscript researcher, and plays for Surbiton Chess Club. The Voynich manuscript is a handwritten book thought to have been written in the 15th or 16th century and comprising about 240 vellum pages,[notes 1] most with illustrations. The author, script, and language remain unknown; for these reasons it has been described as "the world's most mysterious manuscript". Nick Pelling is the author of "Curse of the Voynich: The Secret History of the World's Most Mysterious Manuscript". In this program, he talks about the history of the Voynich Manuscript, Wilfrid Voynich, cryptography and steganography, the art and science of writing hidden messages in such a way that no one apart from the sender and intended recipient suspects the existence of the message, a form of security through obscurity.
