Leben und Wirken
Stephen Gray wurde im Dezember 1666 in Canterbury als Sohn des Färbers Mathias Gray geboren; getauft wurde er am 26. Dezember 1666. Er schlug keine Universitätslaufbahn ein, führte aber möglicherweise Studien in London oder Greenwich unter John Flamsteed durch und erlernte die lateinische Sprache. Sein ständiger Briefwechsel mit Flamsteed ist belegt
In den 1690er Jahren und bis 1716 machte er astrometrische Beobachtungen und führte quantitative und qualitative Untersuchungen von Sonnen- und Mondfinsternissen, Sonnenflecken, den Planeten des Jupiter und vieles mehr durch.
Er wurde Assistent für das geplante Observatorium des Trinity College, Cambridge, sowie 1707/8 Angestellter des Trinity College als Assistent von Roger Cotes. Von 1715 bis 1719 war er Assistent von John Theophilus Desaguliers in Westminster. 1719 erhielt er durch Betreiben des Prinzen von Wales bis zu seinem Tod eine Pension des Charterhouse, London.
Gray führte seit 1708 Pionierexperimente zur Elektrizität durch. So teilte er 1730 die Stoffe in Leiter und Nichtleiter ein. 1731 und 1732 wurde er mit den ersten beiden Copleymedaillen ausgezeichnet.
