On this day in 1911, Pittsburgh officially resumed possession of its H, having been spelled “Pittsburg” in federal documents for some years before that. You might think there would not be much of a celebration a hundred eight years later, but you would be wrong. And the fact that Pittsburgh has a holiday celebrating the last letter of its name tells you more than you could learn from whole books of essays about the character of the city. (And if you follow this link, you will find a recipe for Pittsburgh Chocolate Stout “H” Cake, which celebrates the letter in tangible and edible form.)
