Do you know what else May 5th is?
It’s the day of the very first train robbery in the United States, in North Bend Ohio, in 1885.
It’s the day that the first known observance of what would become our modern Memorial Day holiday took place in 1866, in Waterloo, New York. (Read more about Memorial Day celebrations in this Maine Memory exhibit on the holiday’s origins.)
It’s the day, in 1920, that Sacco and Vanzetti were arrested.
It’s the day, in 1987, that the Iran-Contra hearings began on television.
It’s the day Cy Young, of the Boston Americans, threw the first perfect game of modern baseball, against the Philadelphia Athletics–in 1904. (Here’s the box score for that game for all you statistics freaks.)
And a lot more, of course. But we’ll leave it at that.
And if you want to know more about the origins of Cinco de Mayo–celebrated more in this country than in Mexico, as it turns out–this National Geographic feature is a good place to start.
