From back at the end of October, when Vindigo added Milwaukee, Pittsburgh, and more coverage for Chicago and Washington, DC:

• During the 1850s and '60s many inventors tried to produce a workable typewriter, but none succeeded until 1867, when Milwaukee's Christopher Latham Sholes and inventors Carlos Glidden and Samuel W. Soul patented a writing machine. The machine held a sheet of paper between a rubber platen and smaller rubber cylinder, with a carriage that moved from left to right as the keys, each with a separate mark, number or letter, were struck. Their invention didn't take off until 1873, when the trio contracted with E. Remington & Sons of Ilion, New York, which until then just made rifles and sewing machines, to produce it.
• Baseball's First World Series Game occured in Pittsburgh: A 1903 showdown between the Pirates and the Boston Red Sox. The Pirates eventually lost the series in nine games.
• Chicago-style, or deep dish, pizza was created in 1943 by Ike Sewell and Ric Riccardo of Pizzeria Uno.
• Prince George's County is the home to the world's oldest continuously operating airport, College Park Airport. The Wright Brothers taught flying lessons there in 1909.
• The name for Reston, in Northern Virginia, comes from the initials of Robert E. Simon, who developed the new "town" in the 1960s.
