John,
Readers may be interested to know that Dorrit Hoffleit, shown in your list as born this day in 1907, is still flourishing. This being so, she celebrates her 100th birthday today!

Further to my previous comment, I'm sad to report that Dorrit Hoffleit passed away on April 9, 2007, at the age of 100, having celebrated her 100th birthday on March 12.
