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.
