Loder was born in
London in February 1895, the only son of Conservative MP
Gerald Loder, the fourth son of
Sir Robert Loder, 1st Baronet and member of a prominent
Sussex family, and Lady Louise de Vere Beauclerk, the daughter of the
10th Duke of St Albans and personal friend of
Queen Victoria, who permitted Loder to be christened in the Chapel Royal of
St. James's Palace. Through his mother's family, he was descended from an
illegitimate royal line of
King Charles II. Loder was educated at
Eton College, where he excelled in history and languages, with a particular interest in drama. Although originally intending to go to
Trinity College,
Cambridge, with the outbreak of the
First World War, Loder was instead commissioned into the
4th Battalion of the
Royal Sussex Regiment, and later joined the
Intelligence Corps, seeing service throughout the war in
Gallipoli,
Egypt and Palestine. For his services, he was
Mentioned in Despatches, and left the British Army in 1919 with the rank of
captain. Loder worked as a clerk in the
Foreign Office from 1919 to 1922 and then for two years at the
League of Nations in
Geneva. On 3 June 1920, he married Margaret "Peggy" Tennant, the daughter of prominent Liberal politician and businessman,
Sir Charles Tennant, 1st Baronet. Together they had four children: three sons, Christopher, David and
Robert, and a daughter, Henrietta. Indulging in his interest in
Egyptology, Loder wrote his first book:
The Truth about Mesopotamia, Syria and Palestine. (1923). John and Peggy Loder travelled on a world tour in 1924, including a visit to Australia. Although initially unimpressed, describing
Sydney as "afflicted with so much Victorian architecture of the worst kind", by the end he had warmed to the country, writing that Australia was "a splendid country with splendid people" possessing a "democratic spirit". Returning to England, Loder was narrowly elected as the
Conservative Member of Parliament for
Leicester East in 1924, a seat he held until being defeated in the
1929 General Election. Loder then made several visits to
Bolshevik Russia, writing another book entitled:
Bolshevism in Perspective (1931). In 1931 he returned to the
House of Commons as member for
Lewes, and represented this constituency until succeeding his father on his death as the second
Baron Wakehurst in 1936, who had been raised to peerage in 1934. Loder then entered the
House of Lords. ==Governor of New South Wales==
