Although most of the marginalist economists' methodology was influenced by nineteenth-century classical physics, the work of Francis Ysidro Edgeworth represents the highest point of classical physics influence to the development of mainstream economic methodology. Subsequent leading theorists were not as explicit, although economic theory continued to be influenced by physics as the work of Pareto, Fisher and Samuelson indicates.
