I did a search on what happened today in history. An excellent find - it is Thomas Alva Edison's birthday - born in 1847. The Rockefeller Center in New York commemorated the 75th anniversary of Thomas Edison's first light bulb by lighting a 75,000-watt light bulb in 1954.
If you are in or near Fort Myers, Florida today - go to the Edison & Ford Winter Estates and you will get in free to celebrate his birthday. The month of February has a series of Edison birthday activities and celebrations, including the Edison Festival of Lights.
Do you wonder about the middle name of Alva? A google search brings a number of answers, and the most prevalent story is that its meaning is 'white', related to Latin Albin. It is a popular girl's name in Sweden.
