Sir Ernest Keith White CBE, MC (14 August 1892 – 1 August 1983) was an Australian timber merchant and political activist.
He was born at Gosford to timber contractor Robert John White and Bertha, née Davis. After attending Gosford Public School, he left at twelve and served in the junior cadets and worked for his father. He studied by correspondence with Sydney Technical College, qualifying through the Royal Sanitary Institute as a sanitary engineer. He worked as an inspector for Gosford and Moree shire councils before passing the local government and shire clerk's certificate. On 8 June 1915 he enlisted in the Australian Imperial Force. He married schoolteacher Pauline Marjory Mason, daughter of the mayor of Gosford, on 15 November 1915, and embarked as a second lieutenant in January 1916 as part of reinforcements for the 4th Battalion. He was wounded at Pozières in July and, after returning, rose to become the adjutant in July 1917. At Strazeele in April 1918 he reconnoitred the front line under heavy fire, winning the Military Cross and a mention in despatches. Promoted captain in September, his appointment was terminated on 5 April 1919.
After the war, White returned to work with his father's timber business, moving the headquarters to Sydney. Based in Strathfield, he also bought a timber property near Gloucester and developed land at Terrigal, Wamberal and Forresters Beach. He owned several successful racehorses, which helped finance an opulent house built in 1936. He helped establish the British American Co-operation Movement for World Peace (which became the Australian-American Association) in July 1936, and served as federal and state president; he was significantly involved in the creation of the Australian-American Memorial in Canberra.
