Who is Lytton Strachey? Was it taken in Paris?
Lytton Strachey was from one point of view the brother of Dorothy Bussy, who translated into English much of Gide's work. From another point of view he was one of the Bloomsburys, if that means anything . . . He published in 1918 (significant year) a deplorable but regrettably very influential book entitled "Eminent Victorians". Influential to this day ninety years on we may say!
The photograph was taken in Pontigny in 1923; there are roughly ten more people in the original but we have cropped it. They were literary types who had gathered together there to discuss "Poetry as a Private Treasure, or the Untranslatable".
