Guy Ogilvy is a practicing laboratory alchemist and the author of eight books, including The Alchemist's Kitchen (Bloomsbury), occasionally using the pseudonym Francis Melville. His books have been translated into more than twenty languages and have sold over 750,000 copies. Guy abandoned a promising career in publishing to pursue a personal quest that culminated in an 18-month stint as a cave-dwelling hermit in the mountains of Central North Mexico. Since his return, he has appeared on several television networks to share his expertise on esotericism and alchemy, including Channel 4 and the BBC. He lives in Glastonbury, United Kingdom.
