Alexander Hrennikoff was a Russia

Structural Engineer
, a founder of the Finite Element Method
.
, graduated from the Institute of Communication Engineers in Moscow
, received M.A.Sc. degree from the University of British Columbia
(1933), and D.Sc degree from the Massachusetts Institute of Technology
(1941). From 1933 until his death in 1984 he worked as a professor of Civil Engineering at the University of British Columbia
.
he developed the lattice analogy which models membrane and plate bending of structures as a lattice
framework. While this work received little attention at the time because of the lack of computational power, it is often considered as the turning point in the Time-Line of the Structural Analysis leading to development of the Finite Element Method
. He later extended the lattice models to plate and shell buckling problems, and made important contributions to the plastic design theory of metal structures.
