Lieutenant Colonel Ewan Murray Robson CBE, DSO (7 March 1906 – 26 August 1974) was an Australian lawyer, soldier and a member of the New South Wales Parliament for over twenty years.

After working several years as a solicitor, Robson stood for, and was elected to, parliament on 29 August 1936 at a by-election for the seat of Vaucluse.

[7] Soon after his election Robson joined the UAP but soon joined a group of government backbenchers who were unhappy with the Bertram Stevens government's economic management and the party's control over preselection, becoming prominent in the struggle that led to the resignation of the Premier Stevens and his replacement by Alexander Mair in August 1939.

Attached to the Middle East Tactical School, he rejoined his unit in February 1942 and served with distinction in North Africa, being promoted to major on 8 October 1942.

[11][12][13] On 6 March 1945 he was awarded the Distinguished Service Order, on a recommendation by his Commanding officer, Major General George Alan Vasey.

The KING has been graciously pleased to approve that the following be Mentioned in recognition of gallant and distinguished services in the South-West Pacific: — Lt.Col.

His efficient handling of his command down Markham Valley to Lae, when his battalion carried out a major outflanking movement, was largely responsible for the rapid overpowering and destruction of the enemy.

By his actions he inspired complete confidence in all under his command.In July 1945 he led his unit in the invasion of Balikpapan, Borneo, and in September accepted the surrender of Japanese forces under Major General Michio Uno at Bandjermasin in the Dutch East Indies.

He remarried soon after to Naomi Priscilla Gee at St Peter's Anglican Church, Watsons Bay on 9 December 1950.

Robson then moved a motion to prevent Pat Morton, who was the only person nominated for leader, from taking the leadership.

[21] Robson, however, did not stay long afterward; on 26 July 1957, he resigned his seat,[1] and returned to his legal practice until he retired.

He was appointed a Commander of the Order of the British Empire in the 1966 New Year Honours,[23] On 26 August 1974, Robson died of a heart attack at his Rose Bay home, survived by his second wife and both his sons.
