As he is giving my wife and me a little break right now, I did a quick search on which famous people share the same birthday with him. For November 21st the most admissible to me seems to be Voltaire.
For my older son Alexander's birthday (August 6th) it would be his namesake Alexander Fleming.
And finally regarding my birthday, December 26th, all I came up with first was Mao Zedong, who was born in 1893. Gulp. I had to dig further.
Luckily I found a much more admirable celebrity, and at the same time a founding-father of my profession: Charles Babbage.
Yep, that's definitely better. ;-)
