Happy Birthday Charles Richter! Click here to return to the RF Cafe homepage.Today is World Intellectual Property Day. 1900: Seismologist Charles Richter, who devised the earthquake-measuring scale that bears his name, was born. 1921: The first U.S. broadcast of the weather was made from St. Louis, MO, station WEW. 1933: Arno Penzias, who with Robert Wilson, won the Nobel Prize for discovering the background microwave "Big Bang" radiation, was born. 1962: The Ranger IV space probe became the first U.S. craft to land (a planned crash) on the moon. 1986: The world's worst nuclear accident occurred at the Chernobyl plant in Pripet, Russia (formerly Soviet Union). 1989: Lucille Ball died (hard to believe so long ago).

Note: These historical tidbits have been collected from various sources, mostly on the Internet. As detailed in this article, there is a lot of wrong information that is repeated hundreds of times because most websites do not validate with authoritative sources. On RF Cafe, events with hyperlinks have been verified.
Please submit significant historical events and dates for inclusion in these lists. I will be glad to include your name and birthday. Please do not submit your death date ;-) A couple years ago, I began commemorating the birthdays of notable people and events with special RF Cafe logos. Where available, I like to use images from postage stamps from the country where the person or event occurred.
