==== Scientific work ====
In 1756, Franklin had become a member of the Society for the Encouragement of Arts, Manufactures & Commerce (now the Royal Society of Arts), which had been founded in 1754. After his return to the United States in 1775, he became the Society's Corresponding Member, continuing a close connection. The Royal Society of Arts instituted a Benjamin Franklin Medal in 1956 to commemorate the 250th anniversary of his birth and the 200th anniversary of his membership of the RSA.
The study of natural philosophy (referred today as science in general) drew him into overlapping circles of acquaintance. Franklin was, for example, a corresponding member of the Lunar Society of Birmingham. In 1759, the University of St Andrews awarded him an honorary doctorate in recognition of his accomplishments. In October 1759, he was granted Freedom of the Borough of St Andrews. He was also awarded an honorary doctorate by Oxford University in 1762. Because of these honors, he was often addressed as "Dr. Franklin."
While living in London in 1768, he developed a phonetic alphabet in A Scheme for a new Alphabet and a Reformed Mode of Spelling. This reformed alphabet discarded six letters he regarded as redundant (c, j, q, w, x, and y), and substituted six new letters for sounds he felt lacked letters of their own. This alphabet never caught on, and he eventually lost interest.

=== Return to London and Travels in Europe ===
From the mid-1750s to the mid-1770s, Franklin returned to England and spent much of his time in London., using the city as a base from which to travel. In 1771, he made short journeys through different parts of England, staying with Joseph Priestley at Leeds, Thomas Percival at Manchester and Erasmus Darwin at Lichfield. In Scotland, he spent five days with Lord Kames near Stirling and stayed for three weeks with David Hume in Edinburgh. In 1759, he visited Edinburgh with his son and later reported that he considered his six weeks in Scotland "six weeks of the densest happiness I have met with in any part of my life."
In Ireland, he stayed with Lord Hillsborough. Franklin noted of him that "all the plausible behaviour I have described is meant only, by patting and stroking the horse, to make him more patient, while the reins are drawn tighter, and the spurs set deeper into his sides." In Dublin, Franklin was invited to sit with the members of the Irish Parliament rather than in the gallery. He was the first American to receive this honor. While touring Ireland, he was deeply moved by the level of poverty he witnessed. The economy of the Kingdom of Ireland was affected by the same trade regulations and laws that governed the Thirteen Colonies. He feared that the American colonies could eventually come to the same level of poverty if the regulations and laws continued to apply to them.
Franklin spent two months in German lands in 1766, but his connections to the country stretched across a lifetime. He declared a debt of gratitude to German scientist Otto von Guericke for his early studies of electricity. Franklin also co-authored the first treaty of friendship between Prussia and America in 1785. In September 1767, he visited Paris with his usual traveling partner, Sir John Pringle, 1st Baronet. News of his electrical discoveries was widespread in France. His reputation meant that he was introduced to many influential scientists and politicians, and also to King Louis XV.

=== Defending the American cause ===
One line of argument in Parliament was that Americans should pay a share of the costs of the French and Indian War and therefore taxes should be levied on them. Franklin became the American spokesman in highly publicized testimony in Parliament in 1766. He stated that Americans already contributed heavily to the defense of the Empire. He said local governments had raised, outfitted and paid 25,000 soldiers to fight France—as many as Great Britain itself sent—and spent many millions from American treasuries doing so in the French and Indian War alone.
In 1772, Franklin obtained private letters of Thomas Hutchinson and Andrew Oliver, governor and lieutenant governor of the Province of Massachusetts Bay, proving that they had encouraged the Crown to crack down on Bostonians. Franklin sent them to North America, where they escalated tensions. The letters were finally leaked to the public in the Boston Gazette in mid-June 1773, causing a political firestorm in Massachusetts and raising significant questions in England. The British began to regard him as the fomenter of serious trouble. Hopes for a peaceful solution ended as he was systematically ridiculed and humiliated by Solicitor-General Alexander Wedderburn, before the Privy Council on January 29, 1774. He returned to Philadelphia in March 1775, and abandoned his accommodationist stance.
In 1773, Franklin published two of his most celebrated pro-American satirical essays: "Rules by Which a Great Empire May Be Reduced to a Small One", and "An Edict by the King of Prussia."

=== Agent for British and Hellfire Club membership ===
Franklin is known to have occasionally attended the Hellfire Club's meetings during 1758 as a non-member during his time in England. However, some authors and historians would argue he was in fact a British spy. As there are no records left (having been burned in 1774), many of these members are just assumed or linked by letters sent to each other. One early proponent that Franklin was a member of the Hellfire Club and a double agent is the historian Donald McCormick, who has a history of making controversial claims.
