Presidents Day — #2013

by C. Michael Eliasz-Solomon

It is President’s Day on Monday. That got me to thinking about Washington and Lincoln. Stanczyk, has had an awful lot of mathematical training – the product of a degree from a School of Engineering. It is funny, the teachings that stick with you your whole life. One of the things that I learned that stuck with me was a little factoid from a Probability & Statistics course. I was taught that in a gathering of just of 19 people that the probability that two of them having the same day of birth (not the same year though) would be 50-50. That in any gathering of 19 people it would be a 50% chance of two people celebrating their birthday on the same day each year!

This being President’s Day weekend, I noted that we have had  44Presidents (only 43 different, since Grover Cleveland was the 22nd and the 24th President). So I asked myself did any two Presidents have the same day of  birth? Now if we ignore the Grover Cleveland issue, and we examine the dates of birth of all US Presidents, we do indeed find that two Presidents had the same day of birth. The day in calendar is November 2nd. The two Presidents who share that day are: Warren G. Harding and James K Polk.

Now you might expect that since we have > 38 Presidents, that there should be two pairs of matches. But the odds are only 50-50. So we have just one matching pair of Presidents. There were a lot of near misses (off by one day). If your birth month is not September or June (each of which only had one President) then the odds are pretty good that you, my dear reader, share a birth day with one of the Presidents. I’d say better than 50-50. So click on the link and see for yourself.

Happy President’s Day!

US Presidents in the US Census — #US, #Census, #Genealogy, #History

by C. Michael Eliasz-Solomon

 This year the 1940 Census came out. By law the census is released after 72 years. So anyone you may want to find in the US Census must be at least 72 years old this year.

Do you have the urge to peer at the Presidents in the census? Well then you are in luck! The National Archives has developed a web page on the US Presidents recorded in the US Census. George Walker Bush (#43) has only just turned 66 this month so he is not there. President Bill Clinton will turn 66 next month, ergo he too has not yet appeared in the US Census. So President George H. W. Bush (#41) is the last President to appear in the census. Here is the 1930 Census (CT, Fairfield, Greenwich, ED: 1-134, SHT 4A) in which the president is five years old. Now that is Ancestry.com so you need a membership to view the image.

NARA – Presidents in the Census  (click on the link to go to their website)

I had fun looking at Thomas Jefferson. Many of the Presidents are recorded in more than one census. The links open to a page of census images and even a picture of the President. This might be a novel add-on for K-12 History Curriculum. Also a nice way to work the genealogy subject  into history (or vice-versa). All in all, this genealogical slant on history may spur new ideas for research.

My thanks to the NARA librarians/researchers who provided such a valuable resource!

I also want to thank @NYPLMilstein (twitter) who posted this tidbit on twitter.
