1920: Materials engineer and academic Philip G. Hodge born. He will study the mechanics of elastic and plastic behavior of materials, contributing to plasticity theory including developments in the method of characteristics, limit-analysis, piecewise linear isotropic plasticity, and nonlinear programming applications.
1922: Mathematician, philosopher, and academic Imre Lakatos born. He will be known for his thesis of the fallibility of mathematics and its 'methodology of proofs and refutations' in its pre-axiomatic stages of development.
