JAMES CLERK MAXWELL(1831-1879)

James Clerk Maxwell was a Scottishmathematical physicist. His most notable achievement was to formulate the classical theory ofelectromagnetic radiation, bringing together for the first time electricity,magnetism, and light as manifestations of the same phenomenon.Maxwell's equationsfor electromagnetism have been called the "second great unification in physics after the first one realized byIsaac Newton.

NIKOLA TESLA(1856-1943)

Nikola Tesla was a Serbian American inventor, electrical engineer, mechanical engineer, and futurist best known for his contributions to the design of the modern alternating current electricity supply system.

GEORG OHM(1789-1854)

Georg Simon Ohmwas aGermanphysicistandmathematician. As a school teacher, Ohm began his research with the newelectrochemical cell, invented by Italian scientistAlessandro Volta. Using equipment of his own creation, Ohm found that there is a direct proportionality between the potential difference (voltage) applied across a conductor and the resultantelectric current. This relationship is known asOhm's law.

ANDR-MARIE AMPRE(1775-1836)

Andr-Marie Ampre was a French physicist and mathematician who is generally regarded as one of the main founders of the science of classical electromagnetism, which he referred to as "electrodynamics".

WILLIAM STURGEON(1783-1850)

William Sturgeon was an English physicist and inventor who made the first electromagnets, and invented the first practical English electric motor.

EDWARD ROUTH(1831-1907)

Edward John Routh, was an Englishmathematician, noted as the outstanding coach of students preparing for theMathematical Triposexamination of theUniversity of Cambridgein its heyday in the middle of the nineteenth century. He also did much to systematize the mathematical theory ofmechanics and created several ideas critical to the development of moderncontrol systems theory.

ADOLF HURWITZ(1859-1919)Adolf Hurwitzwas aGerman mathematician. He was one of the early masters of theRiemann surfacetheory, and used it to prove many of the foundational results onalgebraic curves; for instanceHurwitz's automorphisms theorem. In the field ofcontrol systemsanddynamic systems theoryhe derived theRouth-Hurwitz stability criterionfor determining whether a linear system is stable in 1895.

WALTER R. EVANS(1920-1999)

Walter Richard Evans(January 15, 1920 - July 10, 1999) was a noted American control theorist and the inventor of theroot locusmethod in 1948. He was the recipient of the 1987American Society of Mechanical EngineersRufus Oldenburger Medaland the 1988AACC'sRichard E. Bellman Control Heritage Award.

HENDRIK WADE BODE(1905-1982)

Hendrik Alfred Bodewas an American engineer, researcher, inventor, author and scientist, of Dutch ancestry. As a pioneer of moderncontrol theoryand electronictelecommunications he revolutionized both the content and methodology of his chosen fields of research. He also made important contributions tocontrol system theoryand mathematical tools for the analysis of stability of linear systems, inventingBode plots,gain marginandphase margin.

EDWARD LAWRY NORTON(1898-1983)

Edward Lawry Norton was an accomplishedBell Labs engineer and scientist famous for developing the concept of theNorton equivalent circuit.Although interested primarily in a communications circuit theory and the transmission of data at high speeds over telephone lines, Edward L. Norton is best remembered for development of the dual of Thevenin's equivalent circuit.

MORITZ HERMANN VON JACOBI(1801-1874)

Moritz Hermann (Boris Semyonovich) von Jacobi was a German engineer and physicist born inPotsdam. Jacobi worked mainly inRussia. He furthered progress ingalvanoplastics,electric motors, andwiretelegraphy. He deduced themaximum power theorem while studying the transfer of power from abatteryto an electric motor. The theorem is also referred to as Jacobis Law.

GUSTAV ROBERT KIRCHHOFF(1824-1887)

Gustav Robert Kirchhoff was aGermanphysicistwho contributed to the fundamental understanding ofelectrical circuits,spectroscopy, and the emission ofblack-bodyradiationby heated objects. He coined the term"black body" radiationin 1862, and two different sets of concepts (one in circuit theory, and one in thermodynamics) are named "Kirchhoff's laws" after him.

WILHELM CAUER(1900-1945)

Wilhelm Cauerwas a Germanmathematicianandscientist. He is most noted for his work on the analysis and synthesis of electricalfiltersand his work marked the beginning of the field ofnetwork synthesis.

HARALD SCHERING(1880-1959)

Harald Scheringwas a Germanphysicistborn inGttingen. Schering is remembered for invention of theSchering Bridge, which an AC bridge circuit isused to measurecapacitanceand thedissipation factorofcapacitors.

CHARLES WHEATSTONE(1802-1875)

Sir Charles Wheatstone was an English scientist and inventor of many scientific breakthroughs of theVictorian era, including the Englishconcertina, thestereoscope, and thePlayfair cipher. However, Wheatstone is best known for his contributions in the development of theWheatstone bridge, originally invented bySamuel Hunter Christie, which is used to measure an unknown electrical resistance, and as a major figure in the development oftelegraphy.

MAX WIEN(1866 1938)

Max Wienwas a Germanphysicistand the director of the Institute of Physics at theUniversity of Jena.He invented the "Lschfunkensender" (generator of slightly weakened electromagnetic oscillations) during the years 1906 to 1909 and theWien Bridgein 1891.

CARL JACOBI(1804-1851)

Carl Gustav Jacob Jacobi was a Germanmathematician, who made fundamental contributions toelliptic functions,dynamics,differential equations, and number theory. He was also one of the early founders of the theory of determinants; in particular, he invented theJacobian determinant formed from then differential coefficients ofngiven functions ofnindependent variables, and which has played an important part in many analytical investigations.

CARL FRIEDRICH GAUSS(1777-1855)

Johann Carl Friedrich Gauss was a German mathematician, who contributed in many fields including number theory, algebra, statistics, analysis, differential geometry, geodesy, geophysics, electrostatics, astronomy, matrix and optics. He was also one of the founders of Gauss-Siedel Method which is an iterative method named after GermanmathematiciansCarl Friedrich GaussandPhilipp Ludwig von Seidel used to solve alinear system of equations, and is similar to theJacobi method.
