The Disintegration Machine is a short story written about Professor Challenger by Sir Arthur Conan Doyle. Professor Challenger is arguing with people who are persistently calling him on the telephone when his young friend Malone, a reporter for the Gazette, enters and requests Challenger accompany him to inspect the discovery of Theodore Nemor, who claims to have invented a machine capable of disintegrating objects. Skeptical of the invention, Challenger accepts Malone's proposal and accompanies him to the house of Nemor.
