Pittsburgh boasts an impressive history. Unfortunately, there just isn’t enough time in a school career to learn everything there is to know about Pittsburgh. Do you ever wonder what you didn’t learn in school? Here are 11 things about Pittsburgh you might not know.

  1. Emojis started right here in Pittsburgh in 1982.

  1. Mister Rogers’ middle name is McFeely.

  1. Pittsburgh has more bridges than any other city in the world.

  1. The Big Mac was invented in Pittsburgh.

  1. Amelia Earhart once crash-landed in Pittsburgh.

Wikipedia/Public Domain Yes, you read right. Amelia Earhart crash-landed her plane at the former Rodgers Field – the current site of Fox Chapel High School - on August 31, 1928. She miscalculated her landing, coming in too quickly and ended up in a ditch at the end of the runway. She spent the next two days in Pittsburgh while her plane was repaired.

  1. Thank a Pittsburgh institution for pulling the tab on your pop or beer can.

  1. Children’s Hospital’s Poison Center invented the Mr. Yuk sticker in 1971.

Flickr/Kurt Faler How many Pittsburghers remember Mr. Yuk’s green face glaring from products under the sink or other places our nosy little hands went when they were supposed to? Because of the Poison Center at Children’s Hospital, Mr. Yuk became a household name.

  1. Doctors in Pittsburgh performed the world’s first kidney, liver, and heart transplant.

  1. The first bingo game was called right here in Pittsburgh.

Flickr/Michael Cote C’mon. Everyone loves bingo, especially when there are prizes at stake. Hugh J. Ward deserves a nod of recognition for his invention of the game, which was first called in the early 1920s in Pittsburgh.
