Celia Milstein obituary

My friend Celia Milstein, who has died aged 92, was among those who contributed to the invention of monoclonal antibodies, which led to the Nobel prize for medicine of 1984, won by her husband, Cesar Milstein, with Georges Kohler and Niels Jerne. Monoclonal antibodies are used in both treatment and diagnosis of diseases, including cancers, and are being trialled against Covid-19.

Celia was born and grew up in the outskirts of Buenos Aires, to Efrain Prilleltensky, an accountant, and his wife, Ana (nee Davidson), both immigrants from the Ukraine who spoke Yiddish. She recalled her childhood as full of beauty.
