Zara Bate

Dame Zara Kate Bate (; previously Fell and Holt; 10 March 190914 June 1989), was an Australian businesswoman, and the wife of Harold Holt, who was the Australian Prime Minister in 1966 and 1967.
Early life and career.
Zara Kate Dickins was born in Kew, Victoria in 1909. She was educated at Ruyton Girls' School and Toorak College. In 1930, she and her friend Bettine 'Betty' James (later the wife of Sir Roy Grounds) established a dress shop in Little Collins Street. With another friend, she later opened a salon, called "Magg", in Toorak Village. In 1961, a Magg dress won the "Australian Gown of the Year" award.
Her first husband was Colonel James Fell, by whom she had three sons, Nicholas (1937) and twins Sam and Andrew (1939). Their marriage broke down soon after the birth of the twins. They divorced, and in 1946 she married Harold Holt, a Liberal Party politician. He legally adopted her children and gave them his surname. Tom Frame's biography "The Life and Death of Harold Holt" reveals that Holt was the twins' biological father.
Harold Holt was a member of Robert Menzies' cabinet continuously from 1949, becoming deputy Liberal leader in 1956 and Treasurer in 1958. When Menzies retired in January 1966, Holt became Prime Minister. Zara brought a new style and prominence to the role of prime minister's wife. According to Diane Langmore, the author of "Prime Ministers' Wives" (published 1992), Zara Holt "was the only one of the prime ministers' wives to have been a successful businesswoman. No intellectual, and not particularly introspective, she had common sense and a lack of pretension which endeared her to many. [...] The tragedies of life did not make her bitter or cynical; she retained an openness and warmth until her death."
In December 1967, Harold Holt disappeared while swimming near Portsea, Victoria; his body was never recovered.
Zara Holt was created a Dame Commander of the Order of the British Empire in the Queen's Birthday Honours of June 1968, for "devotion to the public interest". In 1968 Dame Zara published "My Life and Harry: An autobiography".
Later life.
On 19 February 1969, Dame Zara Holt married Jeff Bate, a farmer, Liberal politician and member of the Bate family of Tilba, New South Wales. She then became known as Dame Zara Bate. It was the third marriage for both of them. In the early 1970s, Dame Zara promoted Maxwell House instant coffee and Amana microwave ovens and refrigerators in television commercials. After Jeff Bate's death in 1984, Dame Zara retired to the Gold Coast, where she died in 1989 at age 80.
Dame Zara was buried at Sorrento Cemetery, Victoria in the seaside suburb of the same name. Sorrento Cemetery is the closest cemetery to Cheviot Beach, the site from which Holt disappeared.
