Early automobiles - Mack Sennett girls

In 1860s, a bathing outfit could weigh as much as 20 pounds and cover up as much as the full street dress. Later, lighter-weight version features a knee-length gored skirt that buttons over a one-piece romper, topped off with a jaunty cap appeared. By the end of the 19th-century people were flocking to the oceanside beaches for popular seaside activities such as swimming, surf bathing, and diving. A need for a new style bathing suit that retained modesty but was free enough to allow the young lady to engage in swimming was obvious. By 1910 bathing suits no longer camouflaged the contours of the female body. The yards of fabric used in Victorian bathing skirts and bloomers were reduced to show a little more of the figure and to allow for exposure to the sun.

The automobile was first invented and perfected in Germany and France in the late 1890s. Americans quickly came to dominate the automotive industry after WWI. Throughout this initial era, the development of automotive technology was rapid. Hundreds of small manufacturers competing to gain the world's attention. Key developments included the electric ignition system, independent suspension, and four-wheel brakes. Transmissions and throttle controls were widely adopted and safety glass also made its debut. Henry Ford perfected mass-production techniques, and Ford, General Motors, and Chrysler emerged as the “Big Three” auto companies by the 1920s. Car manufacturers received enormous orders from the military during World War II, and afterward automobile production in the United States, Europe, and Japan soared.
