Was Ben Franklin faithful to his wife?

Benjamin Franklin’s fidelity to his wife, Deborah Read, is a subject of historical debate and complexity. They entered into a common-law marriage in 1730 after Deborah’s previous husband disappeared, and they remained married until her death in 1774. During the early years of their marriage, Franklin lived primarily in Philadelphia, and there is no definitive evidence of infidelity during this period. However, Franklin spent significant amounts of time away from home, serving as a colonial agent in London and later as a diplomat in Paris. During his time in Europe, particularly in Paris, Franklin developed close relationships with several women, including Madame Brillon and Madame Helvétius. While these relationships were often intellectual and flirtatious in nature, consistent with the salon culture of the time, some historians suggest they may have been physically intimate. There is no proof of long-term affairs or additional children from these liaisons, but his extended absences and affectionate correspondence indicate that his marital fidelity was not absolute by modern standards. Nevertheless, he maintained a respectful and caring relationship with Deborah, supporting her financially and emotionally despite their physical separation for much of their later married life.
