Note: These
historical tidbits (see daily
list) have been collected from various sources, mostly on the Internet.
As detailed in my
It Happened When? Factoid 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. Many 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. Images used in the logos are often from open source
websites like Wikipedia, and are specifically credited with a hyperlink back to
the source where possible.
