1749 Edward Jenner - British surgeon and a pioneer in the field of vaccination. He developed the smallpox vaccination and administered it for the first time just three days before his 47th birthday

I know I was surprised the first time I read this and I still am that it was developed so early. I'd read also that a queen had herself vaccinated to show everyone there was nothing to fear. I wish I could remember which queen it was - maybe a czarina? Catherine?

1916 The world's first Daylight Savings Act was passed in Britain and clocks were put forward one hour the following Sunday. It was known as "Summer Time"

So - the Brits are to blame.

1996 President Clinton signed a measure requiring neighbourhood notification when sex offenders move in. Megan's Law was named for 7-year-old Megan Kanka, who was raped and killed in 1994

I remember when this happened. I was so tragic. I am glad that there is now Megan's Law.
