Enrico Fermi

Jean Baptiste Joseph Fourier was a French mathematician and physicist best known for initiating the investigation of Fourier series and their applications to problems of heat transfer and vibrations. The Fourier transform and Fourier's Law are also named in his honour. Fourier is also generally... credited with the discovery of the greenhouse effect. Fourier was born at Auxerre , the son of a tailor. He was orphaned at age eight. Fourier was recommended to the Bishop of Auxerre, and through this introduction, he was educated by the Benvenistes of the Convent of St. Mark. The commissions in the scientific corps of the army were reserved for those of good birth, and being thus ineligible, he accepted a military lectureship on mathematics. He took a prominent part in his own district in promoting the French Revolution, serving on the local Revolutionary Committee. He was imprisoned briefly during the Terror but in 1795 was appointed to the École Normale Supérieure, and subsequently succeeded Joseph-Louis Lagrange at the École Polytechnique.

Edward Teller was a Hungarian-American theoretical physicist, known colloquially as "the father of the hydrogen bomb", even though he claimed he did... not care for the title. Teller made numerous contributions to nuclear and molecular physics, spectroscopy , and surface physics. His extension of Fermi's theory of beta decay provided an important stepping stone in the applications of this theory. The Jahn–Teller effect and the BET theory have retained their original formulation and are still mainstays in physics and chemistry. Teller also made contributions to Thomas–Fermi theory, the precursor of density functional theory, a standard modern tool in the quantum mechanical treatment of complex molecules. In 1953, along with Nicholas Metropolis and Marshall Rosenbluth, Teller co-authored a paper which is a standard starting point for the applications of the Monte Carlo method to statistical mechanics.
