This video from 1949 shows Eugene Ormandy conducting the Philadelphia Orchestra. The flutist playing is William Kincaid, who was my teacher’s teacher.
As I was watching the video, it struck me that Ormandy addressed the orchestra, saying “Gentlemen.” In 1949, there were no women in this orchestra. In fact, no woman held a principal position in a major orchestra until Doriot Anthony Dwyer in 1952. She won principal flute of the Boston Symphony and played with them 1952-1990. And Doriot studied with William Kincaid during WWII!
Here is a link to a great article on Doriot.
