Summary

Description
English: Kārlis Johansons' c.1920 "Study in Balance" is a proto-tensegrity sculpture. David Georges Emmerich (1988) reported that the first proto-tensegrity system, called "Gleichgewichtkonstruktion" ("Equilibrium-structure"), was created by Kārlis Johansons in 1920. It was a structure of three bars and seven cords with an eighth cable without tension that interactively altered the configuration while maintaining equilibrium. This configuration was very similar to his own proto-system invention, the "Elementary Equilibrium", with three struts and nine cables. Regardless, the absence of pre-stress, a key characteristic of tensegrity systems, does not allow this particular Kārlis Johansons “sculpture-structure” to be considered one of the first tensegrity structures.

  • Kārlis Johansons (Latvian), birth
