But the City Opera season was limited, and she had to scrounge for jobs for much of the year; on tour with the company, she was forced to sleep in separate hotels from the other musicians, stopped at stage doors as white colleagues walked through, and told to perform hidden from view.
Politically a leftist, Ms. Jones became an insistent activist. When the critic Howard Taubman wrote in The New York Times in 1956 that “if there are capable Negro musicians” they would deserve major-ensemble jobs, she visited him to demonstrate that such musicians did, in fact, exist. She worked on an Urban League report about racism in the music world; within weeks of its publication in 1958, she found herself filling in at the New York Philharmonic. Although the Philharmonic’s records of substitute players are sparse, archival documents name her as the first Black musician to perform as part of the orchestra.
Ms. Jones left City Opera in 1960 at the request of her husband, the doctor and civil rights activist George Kaufman, who asked that she spend more evenings with him and their three children. But Leopold Stokowski, long a fan, quickly tapped her for his American Symphony Orchestra, for which she performed until 1972. She was one of the driving forces behind the founding of the integrated Symphony of the New World in 1965, and she joined other Black musicians to urge that the initial rounds of auditions be held blind, with the musicians behind a screen, to reduce bias. The San Francisco Symphony was an early adopter of that approach.
“I wouldn’t have gotten the job if the screen wasn’t in play,” she later told Dr. Wang. “I’m the recipient of a thing that I worked on.”
Ms. Jones’s marriage to Dr. Kaufman ended in divorce in 1964. In addition to her daughter Ms. Stanley, she is survived by her son, Stephen Kaufman, a violinist and performance artist also known as Thoth; another daughter, Harriet Kaufman Douglas; and three grandchildren.
As a single mother, Ms. Jones often had to take her children to rehearsals, she told The Times in 1965. She hoped, she said, that she offered them an example.
“All youngsters need an image to project to, Negro youngsters even more than white,” she said. “When they can see Negroes playing in the orchestra, they may feel that they can get there someday, too.”
