Julius and Agnes Zancig Autograph
Julius and Agnes Zancig were stage magicians and authors on occultism who performed a spectacularly successful two-person mentalism act during the late 19th and early 20th centuries. Julius Zancig (1857–1929) – born Julius Jörgensen in Copenhagen, Denmark and his wife Agnes Claussen Jörgensen (c.1850s −1916); also born in Copenhagen, and known as Agnes Zancig, were the originators of the routine.
From their first professional appearance in the 1880s, until her death in 1916, the act consisted of Julius and his wife Agnes Zancig. Julius and Agnes were very close to one another in real life as well as on stage and were billed as "Two Minds With But a Single Thought." They had been childhood sweethearts in Denmark but grew apart, then met and fell in love again after both had emigrated to the United States. They were married in 1886. Theirs was the most popular and famous version of the act, and was successful for 30 years.
In 1921 a small (but by itself essentially useless) portion of the Zancigs' methodology was published by their friend and fellow mentalist-magician, Alexander the Crystal Seer. Writing in 1929, the year of Julius Zancig's death, the British magician Will Goldston also attempted to describe the code in some depth, but he did not reveal its entirety. In the 1940s Robert Nelson published a simple stage code which superficially resembled that of the Zancigs, but it did not permit the diversity of expression they had achieved.
To this day, the Zancig Code, also known as "Two Minds With But a Single Thought," is considered by many professional mentalists to be the most dauntingly complex two-person communication system of its type ever devised.
