Structural balancing was first applied (but not introduced as a term) by Chamberlin‎<ref name=Chamberlin_1910>Chamberlin, R. T., 1910, The Appalachian folds of central Pennsylvania: The Journal of Geology, v. 18, no. 3, p. 228-251.</ref> to predict the geometry of the subsurface based on outcrop relationships. At the start of the Twentieth Century, deciphering the evolution of mountain belts and orogens represented an early stage of studying the kinematics associated with deformation.‎<ref name=Peach_1907>Peach, B.

In the 1960s, Bally et al (1966) and Dahlstrom (1969) first used restoration as a tool to assess interpretation and predict geometry of structures whose interpretations were highly uncertain.‎<ref name=Ballyetal_1966>Bally, A. W., Gordy, P. L., & Stewart, G. A. (1966). Structure, seismic data, and orogenic evolution of southern Canadian Rocky Mountains. Bulletin of Canadian Petroleum Geology, 14(3), 337-381.</ref>‎<ref name=Dahlstrom_1969 /> Advancements in computer science at the end of the century has had great impact in converting balancing and restoration concepts into software applications that can handle structural analysis of 2D sections and maps. Most recently as computer power increased and algorithms enhanced, commercial software applications allowed for the handling of 3D volumes balancing and restoration.
