In addition to naming the most powerful people in the world (US President Barack Obama tops that list), Forbes had former NIH director Elias Zerhouni choose the seven most influential people in medicine. Zerhouni names the current NIH director Francis Collins as the most important person in that realm, followed by National Institute of Allergy & Infectious Diseases director Anthony Fauci. Also making an appearance are David Baltimore, Harold Varmus, and Shinya Yamanaka.
