Peter Collinson, a prosperous English Quaker merchant, was the Library Company's agent in London. He became a close professional and personal associate of Franklin's. Collinson shared Franklin's interest in many aspects of science, including "the electrical fire," and provided some of his equipment for experimentation. A Fellow of the Royal Society, he read Franklin's letters describing his elecrical experiments to the Society and published them in 1751. By 1754, supplements had been added, and the volume was soon published in French, German, and Italian, giving Franklin a significant reputation throughout Europe.
