Ruth Weiss, a South African journalist who covered apartheid in the early 1990s and later wrote about the brutal white regime in Rhodesia, died on Sept. 5 in Aalborg, Denmark. She was 101.

Her long life and the hundreds of articles and many books she wrote were shaped by twin experiences of discrimination: first, as a girl, when her life was upended after the Nazis came to power in 1933, and then, three years later, when her family immigrated to Johannesburg on one of the last refugee boats allowed into South Africa.

From being an object of exclusion and persecution, she became a witness to it. And like many other refugee Jews, she became a determined opponent of apartheid.

Addressing the state Parliament of North Rhine-Westphalia in Germany in 2023, Ms. Weiss said, “Racism, antisemitism and misanthropy know no borders. These are injustices that must be fought everywhere.”
