The Osage Nation bestowed this title (“She of Two Standards”) on one of their own, the late prima ballerina Maria Tallchief, born 1925 in Fairfax, Oklahoma. It’s hard to imagine something in the realm of dance that she didn’t do, up to and including marrying George Balanchine, which she did in 1946. (They split in 1951.)
Here, we see her with Rudolf Nureyev in 1962:
Tallchief took a fall last December and broke her hip; complications from the injury caused her death Saturday.
