Who are the most important scientists in life science currently? - (Jun/30/2010 )

in each life science discipline there are, of course, some leaders but who is most important beyond her/his faculty?

"Importance" can be discussed in various directions: importance in science, or importance in making a topic popular or important to explain us science or etc

any contribution is appreciated

to drop a name, my favourite is Hiroaki Kitano

E. O. Wilson
