|Ms. Boulanger with Igor Stravinsky|
I have a fascination with charts, like the "six degrees of separation" type charts that resemble family trees or mind mapping graphs.
I even laid a few out years ago, to see, interestingly, who is connected with whom in what way on what projects, and it's interesting to see how people's lives and projects and work intertwine and work together and butterfly effect and little decisions cause big waves, blah blah.
Think of people in history whose family trees would have influenced entire empires or continents. Genghis Khan potentially fathered thousands of children (with a number of his morganatic wives, those benign considered legitimate children), and other historical figures likes King Solomon (and others) who had hundreds of wives would have had massive, earth-shatteringly large type family trees.
Take that idea, and apply it to pedagogy (not the fathering of children as much as nurturing students' creativity and talents), and you will have some idea of what Nadia Boulanger did for the world. Her sphere of influence is staggering, and many of the pieces or people or performances that you appreciate or enjoy from the 20th century could very likely be influences from her or her students.
Born Juliette Nadia Boulanger, she came from a musical family, her father and mother
