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.
All will eventually be either verified or removed.
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 ;-)
