· 1452–1519 Leonardo da Vinci made many contributions

· 1638: Galileo Galilei published the book “Two New Sciences” in which he examined the failure of simple structures

· 1660: Hooke’s law by Robert Hooke

· 1687: Isaac Newton published “Philosophiae Naturalis Principia Mathematica” which contains the Newton’s laws of motion

· 1750: Euler–Bernoulli beam equation

· 1700–1782: Daniel Bernoulli introduced the principle of virtual work

· 1707–1783: Leonhard Euler developed the theory of buckling of columns

· 1826: Claude-Louis Navier published a treatise on the elastic behaviors of structures

· 1873: Carlo Alberto Castigliano presented his dissertation “Intorno ai sistemi elastici”, which contains his theorem for computing displacement as partial derivative of the strain energy. This theorem includes the method of *least work* as a special case

· 1874: Otto Mohr formalized the idea of a statically indeterminate structure.

· 1922: Timoshenko corrects the Euler-Bernoulli beam equation

· 1936: Hardy Cross‘ publication of the moment distribution method which was later recognized as a form of the relaxation method applicable to the problem of flow in pipe-network

· 1941: Alexander Hrennikoff submitted his D.Sc thesis in MIT on the discretization of plane elasticity problems using a lattice framework

· 1942: R. Courant divided a domain into finite subregions

· 1956: J. Turner, R. W. Clough, H. C. Martin, and L. J. Topp’s paper on the “Stiffness and Deflection of Complex Structures” introduces the name “finite-element method” and is widely recognized as the first comprehensive treatment of the method as it is known today
