Happy Birthday, Robert Bunsen!

Rocking beard, man.
He's 200 years young today.  Read more about this excellent chemist here on Wikipedia.  He developed one of the most useful pieces of scientific laboratory equipment around.  Many students have horror stories from their first attempts at lighting a Bunsen burner in chemistry class.  In addition, he is the namesake inspiration for one of the Muppets Dr. Bunsen Honeydew.
