Happy Birthday to Augustus De Morgan. - Please click here to visit RF Cafe.

1806: Augustus De Morgan, who formulated De Morgan's laws for Boolean algebra, was born. 1901: Merle Tuve who first used pulsed radio waves to explore the ionosphere, was born. 1941: The BBC began using the first four notes of Beethoven's Fifth Symphony as a morale-boosting motif (in Morse Code, "dit-dit-dit dahhh" stands for the letter "V" as in "Victory"). 1950: President Truman ordered the Air Force and Navy into the Korean conflict. 1954: The world's first atomic power station began producing electricity in Obninsk, USSR. 1962: Ross Perot began Electronic Data Systems (EDS). 1976: Palestinian extremists hijacked an Air France plane in Greece with 246 passengers and 12 crew onboard. 1978: The first pen with truly erasable ink, the Gillette Eraser Mate, was invented. 1983: Maxie Anderson, who co-piloted the first transatlantic balloon flight on the Double Eagle II, died.

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.
