The 18 greatest conductors of all time
4. Nadia Boulanger
Nadia Boulanger made her conducting debut in 1912, at the age of just 24 and rose to become one of the most respected conductors and teachers of all time. She taught everyone who was anyone in the 20th century, from Copland to Elliott Carter. She's also awesome. When asked by a reporter about being a woman conductor she replied: "I've been a woman for a little over 50 years and have gotten over my initial astonishment."
