[3] Along with Eileen Power, he wrote and edited a 26-volume series published by George Routledge & Sons, The Broadway Travellers.
Ross joined the staff of the British Museum in 1914, appointed to catalogue the collections of Sir Aurel Stein.
In January 1940, shortly after the outbreak of WWII in Europe, Ross was named head of the British Information Bureau at Istanbul with the rank of Counsellor.
As an acquaintance of the deceased Turkish leader Mustafa Kemal Ataturk, Ross was eager to serve his country from Turkey.
However, the loss of his wife Dora in April 1940 was more than he could bear, and Sir Ross himself died in Istanbul at age 69 in September 1940.
