The fourth dimension entered the imagination of Victorian England with the American psychologist Henry Slade. In London, he claimed to be able to operate in the fourth dimension. He was arrested for fraud, but some physicists (such as Johann Zollner of the University of Leipzig) took him seriously and organized experiments on him, such as interlacing two separate wooden rings, reversing the right-handed pattern of a shell, and extracting the contents of a bottle without opening it.
