This video from 1949 shows Eugene Ormandy conducting the Philadelphia Orchestra.  The flutist playing is William Kincaid, who was my teacher’s teacher.  Video here 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.
