Robert Moray
Sir Robert Moray served (after 1633) in the army of the Louis XIII of France. He was promoted colonel of the elite Scots Guards (1648), and become Privy Councillor (1651) and Lord of Exchequer for Scotland. He was an amateur scientist and one of the Founder Fellows (6 March 1661) of the 'Invisible College' of natural philosophers (the later Royal Society). Moray told Charles II of England about this scholarly venture and secured his approval (15 July 1662). See: Robertson, 1922; Martin, 1960, pp. 239–50; ODNB.
In a letter from Oldenburg to Moray, the former refers to Spinoza as an 'odd philosopher':
I should have said nothing more at this time, but that just now there comes to my hands a letter from an Odd Philosopher, that lives in Holland but no Hollander, who having lately conversed with M. Hugens writes to me thus: 'Kircheri mundum subterranaeum … errare [here follows the Latin text of Fragment 30A].
