Daily Life
Morning
Franklin was a committed early riser, waking around five in the morning. He devoted his mornings to study, reading, and correspondence, often while taking an air bath — a hygienic practice he considered excellent for his health. In Philadelphia, he would then oversee his printing shop.
Afternoon
His afternoons were dedicated to business affairs, political meetings, or scientific experiments in his study. In Paris, he received diplomats and philosophers, played chess, or strolled through the gardens of Passy, beloved by Parisians who greeted him with great respect.
Evening
Franklin's evenings were lively and intellectually engaged. In Philadelphia, he frequented his discussion club, the Junto, which he had founded to debate philosophy and politics. In Paris, he shone in the literary salons, conversing with Voltaire, Turgot, and the Encyclopédistes over a glass of Burgundy wine.
Food
Franklin had relatively frugal eating habits for a man of his standing, true to his maxims on temperance. He nonetheless enjoyed fine French cuisine during his time in Paris and was particularly fond of cider and wine. In his youth, he was temporarily vegetarian in order to save money to buy books.
Clothing
Franklin deliberately dressed simply and plainly, refusing the powdered wig and embroidered garments fashionable at European courts. In Paris, he wore a fur robe and a marten-fur cap, which set him apart from the aristocracy and delighted Enlightenment philosophers as a symbol of American republican simplicity.
Housing
In Philadelphia, Franklin lived in a comfortable red-brick house typical of colonial architecture, with a garden and a study filled with scientific instruments. In Paris, he resided in the elegant Hôtel de Valentinois in Passy, made available by a French admirer, surrounded by gardens overlooking the Seine.
