A very large, old building was...

A very large, old building was being torn down in Chicago to make room for a new skyscraper.
Due to its proximity to other buildings it could not be imploded and had to be dismantled floor by floor.
While working on the 49th floor, two construction workers found a skeleton in a small closet behind the elevator shaft. They decided that they should call the police.
When the police arrived they directed them to the closet and showed them the skeleton fully clothed and standing upright. They said, "This could be Jimmy Hoffa or somebody really important."
Two days went by and the construction workers couldn't stand it any more, they had to know who they had found. They called the police station and said, "We're the two guys who found the skeleton in the closet and we want to know if it really was Jimmy Hoffa."
The cop said, "Well, it wasn't Jimmy Hoffa, but it was somebody kind of important."
"Well, who was it?"
"The 1956 Polish National Hide-and-Seek Champion!"

X-rays

In 1895, Wilhelm Röntgen first observed X-rays during an experiment at Würzburg University. After further investigation, on 1 Jan 1896, he notified other scientists of his discovery of this new radiation that would become known as X-rays. He sent copies of his manuscript and some of his X-ray photographs to several renowned physicists and friends, including Lord Kelvin in Glasgow and in Paris. On 5 Jan 1896, Die Presse published the news in a front-page article which described his investigations and suggested new methods of medical diagnoses might be made with this new kind of radiation.«*
