Levenstein begins in 1786, when Thomas Jefferson instructed young upper-class American men to travel overseas for self-improvement rather than debauchery. Inspired by these sentiments, many men crossed the Atlantic to develop "taste" and refinement. However, the introduction of the transatlantic steamship in the mid-nineteenth century opened France to people further down the class ladder. As the upper class distanced themselves from the lower-class travelers, tourism in search of culture gave way to the tourism of "conspicuous leisure", sex, and sensuality. Cultural tourism became identified with social-climbing upper-middle-class women. In the 1920s, Prohibition in America and a new middle class intent on "having fun" helped make drunken sprees in Paris more enticing than trudging through the Louvre. Bitter outbursts of French anti-Americanism failed to jolt the American ideal of a sensual, happy-go-lucky France, full of joie de vivre. It remained Americans' favorite overseas destination.
