When shortly afterwards Lord Macclesfield took the Act of Settlement to the elector of Hanover in 1701, the younger Andrew Fountaine accompanied him and thus became known in the courts of Europe in what became the first of his two grand tours. He was in correspondence with Gottfried Leibniz between 1701 and 1704, was admitted to the Royal Society of Berlin, became friends with Cosimo III de' Medici, Grand Duke of Tuscany on travelling to Italy in 1702, and was part of the mission to the States General of the Dutch Republic in 1705 (using it as an opportunity to add to his book and coin collections).
