Therkeld Jorgensen (1886 - 1985)

1886 - In the year that Therkeld Jorgensen was born, on January 5th, Scottish novelist Robert Louis Stevenson's book the Strange Case of Dr Jekyll and Mr Hyde was published. Immediately popular, the paperback book was sold for $1 in the U.S. - almost $25 today. Stevenson's stepson said that he wrote the first draft in under 3 days.

1918 - Therkeld was 32 years old when on November 1, an elevated train on the Brooklyn line of the subway - driven by an inexperienced operator because of a strike - tried to navigate a turn at 30mph. The limit on the curve was 6 mph. The 2nd and 3rd cars of the 5 car wooden train were badly damaged and at least 93 people were killed, making it the deadliest crash in New York subway history.

1920 - When this person was 34 years old, the National Football League, first called the American Professional Football Association, was created. College football was more popular than pro football and rising player salaries were bankrupting league owners. In response, owners created the NFL, using the pro baseball association as a model. Eleven teams were formed: the Akron Pros, Canton Bulldogs, Cleveland Indians, Dayton Triangles, Decatur Staleys, Hammond Pros, Massillon Tigers, Muncie Flyers, Racine Cardinals, Rochester Jeffersons and Rock Island Independents.

1977 - This person was 91 years old when on January 21st, President Carter pardoned "draft dodgers" - men who avoided the draft during the Vietnam War. He fulfilled a campaign promise with the pardon. But it only applied to civilian evaders - the estimated 500,000 to 1 million active-duty personnel who went AWOL were not included.

1985 - In the year of Therkeld Jorgensen's passing, in May, a paper published in Nature by three British scientists reported that a huge hole was discovered in the ozone layer over the Antarctic. It was much larger than expected and is due to the use of manmade chemicals.
