* Sarah d'Everard (1816–1900}}

Professor Doctor [[Barons of Yonderre|Baron]] '''Rachet Hercule Peter d'Everard''' <small>[[Order of the Kestrel|OC]]</small> (December 3, 1838 – February 13, 1922) was a [[Yonderre|Yonderian]] physicist, chemist and [[Nobility in Yonderre|nobleman]] most notable for his discovered that electric currents create magnetic fields, which was the first connection found between electricity and magnetism. He also developed mathematical formulae to describe phenomena such as the relation between the refraction of light and the density of a pure transparent substance and the relation between a metal's electrical and thermal conductivity and temperature. A leader of the [[Yonderian Golden Age]], d'Everard made several discoveries in the field of physics and served as a professor at the [[University of Collinebourg]].

d'Everard was the father of world famous [[Paleontology in Yonderre|paleontologist]] [[Phillipe d'Everard (paleontologist)|Phillipe d'Everard]].

In 1865, d'Everard discovered and subsequently published his discovery that a compass needle was deflected from magnetic north by a nearby electric current, confirming a direct relationship between electricity and magnetism. d'Everard made this discovery incidentally during a lecture, although he had, in fact, been looking for a connection between electricity and magnetism since 1862, but was quite confused by the results he was obtaining. For his discovery, the [[Grand Duke of Yonderre]] [[Giles IV Sentinelleau]] awarded d'Everard the [[Order of the Kestrel]] in 1866 and granted him 3,000 [[Yonderian Argent|Argents]] for further research.
