To propose somebody for membership, send email to Marc Abrahams at Harvard University marca /ate/ chem2.harvard.edu. Your email needs to include evidence of your luxuriant, flowing hair (a photo) and your credentials as a scientist. Some current members have impressive hair, see Simon Gregory, Carlisle Landel and Sterling Paramore for examples. Honorary and historical members include Dr. Brian May (Queen guitarist / astrophysicist), Dimitry Mendleyev and Albert Einstein, “Physicist. Bon vivant. A bold experimentalist with hair”.
So, if you are a scientist with a copius coiffure, ask yourself, will you ever get another chance to be in such distinguished company?
