In 1806, having reached the Pacific Coast, explorers Lewis and Clark begin their journey back east. This should really be "National U-Turn Day." At least they knew they had it the midway point of their trip.
On this date in 1840, the very first picture of the moon was taken.
Up until that point, it was very shy. And cameras hadn't been invented yet.
I can't imagine that would have been too difficult. It's not like you have catch it when it's still.
What does the moon say when you take it's picture? Cheese!
Of course, the moon wanted to know if they got his good side. To be clear, it was a picture of the moon... not a moon.
In 1918 during World War I, Germany initiated the use of a terrifying new weapon, a 25-foot cannon nicknamed "Big Bertha." Obviously, by the outcome of the war, it worked about well as the "Big Bertha" that got stuck digging a tunnel through Seattle for two years.
On this date in 1929, the very first telephone was installed in the White House.
Up until then, prank calls had to be made by telegram... and it just wasn't as funny.
Up until that time, the president always had to go out for pizza.
Up until then, there was nothing really to bug.
And, to no one's surprise, the very first pizza was also ordered from the White House.
