Currently in its fourth fifth of existence, Mummenschanz remains one of the most successful theater groups in the world. Formed in 1972 by Swiss artists Bernie Schürch and Andres Bossard with Swiss-American artist Floriana Frassetto, the pioneering performance troupe created a non-verbal theatrical language that transcended the traditional barriers of nationality and culture. The group had its breakthrough during an extended Broadway run at the Bijou Theatre in New York City from 1977-1980. Never before and or since has a show without words or music succeeded on Broadway for three consecutive years. Since then, the group has toured continuously around the globe, performing in renowned festivals and theaters worldwide.
