How Thomas Keller "gave birth" to so many of the great chefs today

I was just thinking about how some of the great chefs mentor so many people. Here are some people that worked for Thomas Keller: Grant Achaz, Curtis duffy, Rene Redzepi, Eric Ziebold, Tom Colichio, Cory Lee, Jonathon Benno, etc. Thomas Keller makes the people that work for him so much better. I think this is crazy how so many amazing chefs worked for him. This could be said th same about the Adria brothers, Daniel Boulud, Joel Robucon, etc.
I am in the process of making a chef "family tree" where it will show for instance that Marco Canora worked for Colicchio who worked for Keller. I think it will be a really cool think to look at and see how some chefs have influenced the culinary world in so many ways.
