Olivia Newton-John was born on September 26, 1948 in Cambridge, England, to a Welsh father, Brinley ("Bryn") Newton-John, and a German-born mother, Irene Born, the eldest child of the Nobel prize-winning atomic physicist Max Born.

Her mother's family had left Germany before World War II to avoid the Nazi regime (Newton-John's maternal grandfather was Jewish, and her maternal grandmother was of paternal Jewish ancestry).
