Inge Ginsberg, who fled the Holocaust, helped American spies in Switzerland during WWII, wrote songs in Hollywood and, in a final assertion of her presence on earth, made a foray into heavy metal music as a nonagenarian, died July 20 in a care home in Zurich. She was 99.

She was the frontwoman for the band Inge and the Tritone Kings, which competed on television on “Switzerland’s Got Talent,” entered the Eurovision Song Contest and made music videos. Whatever the venue, Ms. Ginsberg would typically appear in long gowns and pearls and flash the two-fingered hand signal for “rock on” as she sang about the Holocaust, climate change, mental health and other issues.
