Hutcheson taught him, while Hume knew him from Smith’s professorship in Glasgow (they became best friends). Adam, Black, Stewart and Hutton were members of Smith’s weekly ‘Oyster Club’ in Edinburgh. Helvétius and d’Alembert were met at d’Holbach’s intellectual/libertarian salon in Paris, as was Turgot (who may have given Smith some of his economic ideas there). Johnson and he repelled each other, Bentham and Rochefoucauld corresponded with him, while Quesnay was credited in his ‘Wealth of Nations’. He met Voltaire when he spent 2 months in Switzerland, and visited Smollett when Smollett visited Edinburgh.
