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.
