Maurice Anthony Biot (May 25, 1905 – September 12, 1985) was a Belgian-American applied physicist. He made contributions in thermodynamics, aeronautics, geophysics, earthquake engineering, and electromagnetism. Particularly, he was accredited as the founder of the theory of poroelasticity. Born in Antwerp,

Research and Development. Biot's early work with von Kármán and during the World War II working for the US Navy Bureau of Aeronautics led to the development of the three-dimensional theory of aircraft flutter. During the period between 1932 and 1942, he conceived and then fully developed the

, and thermorheology. Biot’s interest in the non-linear effects of initial stress and the inelastic behavior of solids led to his mathematical theory of folding of stratified rocks. In the period between 1935 and 1962 Biot published a number of scientific papers that lay the foundations of the theory of poroelasticity (now known as Biot theory), which describes the mechanical behaviour of fluid-saturated

A Biot Conference on Poromechanics was established and was held at Université catholique de Louvain, Belgium (1998), Universite Joseph Fourier, France (2002), University of Oklahoma, USA (2005), Columbia University, USA (2009), and Technical University of Vienna, Austria (2013).
