Mamaine and Koestler were divorced in 1952.

Mamaine Koestler (7 September 1916 – 2 June 1954) was the second wife of the author Arthur Koestler. She married Koestler on 25 April 1950. They separated on amicable terms on 15 August 1952[1] but remained very close right up to her sudden and unexpected death. She died on 2 June 1954 in a London hospital of an episode of acute asthma.

She was born Mamaine Paget in Melton, Suffolk, U.K., one of two identical twins. Her parents were Eric Morton Paget and Georgina Byng Paget (they both happened to have the surname ‘Paget’ but were unrelated). Her mother died of childbirth complications a week after giving birth to Mamaine and her twin sister Celia. The twins were brought up by their father, who was aged fifty at the time of their birth, with the help of a nanny, much loved by the twins.

Her childhood, education and early life, and details of her life with Koestler, both before and after her marriage, are candidly described in the book Living with Koestler: Mamaine Koestler's Letters 1945-51, written, compiled and edited by her twin Celia Goodman, published by Weidenfeld and Nicolson, London 1985. ISBN 0297785311.

Morality and Arthur Koestler By David Cesarani was “paradoxical” for Mamaine Paget, Koestler’s second wife, to have made common cause with his secretary, Cynthia Jeffries, when the two women became the objects of Koestler’s abuse. Why shouldn’t wife and secretary rally to each other? The paradox comes from the fact that two years earlier Koestler began an affair with Cynthia while Mamaine was gravely ill in hospital............ the illegal and dangerous abortions that were the price several women paid for their liaisons with Koestler, painful outcomes for which Koestler had little time or patience.
