He set forth as a sort of minister plenipotentiary to London, where he had at one time worked as a journeyman printer. He had left London an obscure, impoverished boy; he was returning as a famous man of science, retired from worldly business on an assured income. He remained in England for five years, and so full of pleasure, interesting occupation, and fame were those years that it is remarkable that he was willing to come back to Pennsylvania.
He secured lodgings for himself and his son William at Mrs. Stevenson’s, No. 7 Craven Street. Here he lived all of the five years and also during his subsequent ten years’ residence in London. He had been recommended to her house by some Pennsylvania friends who had boarded there; but he soon ceased to be a mere lodger, and No. 7 Craven Street became his second home. He and Mrs. Stevenson became firm friends, and for her daughter Mary he formed a strong attachment, which continued all his life. His letters to her are among the most beautiful ever written by him, and he encouraged her to study science. “In all that time,” he once wrote to her, referring to the happy years he had spent at her mother’s house, “we never had among us the smallest misunderstanding; our friendship has been all clear sunshine, without the least cloud in its hemisphere.”
Mrs. Stevenson took care of the small every-day affairs of his life, advised as to the presents he sent home to his wife, assisted in buying them, and when a child of one of his poor English relatives needed assistance, she took it into her house and cared for it with almost as tender an interest as if she had been its mother. Many years afterwards, in a letter to her written while he was in France, Franklin regrets “the want of that order and economy in my family which reigned in it when under your prudent direction.”[22]
The familiar, pleasant life he led with her family is shown in a little essay written for their amusement, called “The Craven Street Gazette.” It is a burlesque on the pompous court news of the English journals. Mrs. Stevenson figures as the queen and the rest of the family and their friends as courtiers and members of the nobility, and we get in this way pleasant glimpses of each one’s peculiarities and habits, the way they lived, and their jokes on one another.
He had an excellent electrical machine and other apparatus for experiments in her house, and went on with the researches which so fascinated him in much the same way as he had done at home. It was at No. 7 Craven Street that he planned his musical instrument, the armonica, already described, and exhibited it to his friends who came to see his electrical experiments. He quickly became a member of all the learned societies, was given the degree of doctor of laws by the universities of St Andrew’s, Edinburgh, and Oxford, and soon knew all the celebrities in England. But he does not appear to have seen much of that burly and boisterous literary chieftain, Dr. Johnson. This was unfortunate, for Franklin’s description of him would have been invaluable.
Peter Collinson, to whom his letters on electricity had been sent, of course welcomed him. He became intimate with Dr. Fothergill, the fashionable physician of London, who had assisted to make his electrical discoveries known. This was another of his life-long friendships: the two were always in perfect sympathy, investigating with the enthusiasm of old cronies everything of philosophic and human interest.
Priestley, the discoverer of oxygen and one of the foremost men of science of that time, became another bosom friend, and Franklin furnished him the material for his “History of Electricity.” William Strahan, the prosperous publisher and friend of Dr. Johnson, also conceived a great liking for the Pennsylvania agent. Strahan afterwards became a member of Parliament, and was fond of saying to Franklin that they both had started life as printers, but no two printers had ever risen so high. He was a whole-souled, jovial man, wanted his son to marry Franklin’s daughter, and wanted Mrs. Franklin to come over to England and settle there with her husband, who, he said, must never go back to America. He used to write letters to Mrs. Franklin trying to persuade her to overcome her aversion to the sea, and he made bets with Franklin that his persuasions would succeed.
We need not wonder that Franklin spent five years on his mission, when he was so comfortably settled with his own servant in addition to those of Mrs. Stevenson, his chariot to drive in like an ambassador, and his son William studying law at the inns of court. During his stay, and about the year 1760, William presented him with an illegitimate grandson, William Temple Franklin. This boy was brought up exclusively by his grandfather, and scarcely knew his father, who soon married a young lady from the West Indies. In his infancy Temple was not an inmate of the Craven Street house, but he lived there afterwards during his grandfather’s second mission to England, and accompanied him to France.
The birth of Temple and his parentage were probably not generally known among Franklin’s English friends during this first mission. It has been said also that William’s illegitimacy was not known in London, but this is unlikely. It did not, however, interfere with the young man’s advancement; for in 1762, just before Franklin returned to America, William was appointed by the crown governor of New Jersey. This honor, it is said, was entirely unsolicited by either father or son, and the explanation usually given is that it was intended to attach the father more securely to the royal interest in the disputes which were threatening between the colonies and the mother country.
William and his father were on very good terms at this time. Every summer they took a little tour together, and on one occasion travelled in Holland. On a visit they made to the University of Cambridge they were entertained by the heads of colleges, the chancellor, and the professors in the most distinguished manner, discussed new points of science with them, and with Professor Hadley experimented on what was then a great wonder, the production of cold by evaporation. They wandered also to the old village of Ecton, where the Franklins had lived poor and humble for countless generations, saw many of the old people, and copied inscriptions on tombstones and parish registers. But Scotland they enjoyed most of all. There they met Lord Kames, the author of the “Elements of Criticism,” and the historians Hume and Robertson. It was an atmosphere of philosophy and intelligence which Franklin thoroughly enjoyed. “The time we spent there,” he wrote to Lord Kames, “was six weeks of the densest happiness I have met with in any part of my life.”
