This is a minor point, but I like the joke she made in the beginning about her height. Not only was it funny, but I was unaware that she was 5'1", and think that makes her accomplishments even more impressive and says something about her tenacity, given that 58% of F500 CEOs are over 6 feet tall.
Definitely unusual. Most female executives are above average in terms of height too - Sheryl Sandberg, Ruth Porat, Susan Wojcicki, Marissa Mayer are all 5'8"+
Napoleon and Hitler were both shorter than the average and they were powerful leaders. Looking at their place in history I am confused about the research implications. I just search on Internet and the list is very large: http://www.ranker.com/list/shortest-world-leaders-from-histo... we cannot forget Putin!
