Arthur Sneezum, park-keeper, probably in the Maldon Road Recreation Ground (the Park). Possibly the shelter and fountain are behind. He died in 1955.
See also the Essex County Chronicle for 5 November 1915 and for 26 May 1916.
There are a considerable number of photos of the Sneezum family, i.e. M150, M201, M922 to M927, M929 to M943, and M1086. There are also references to them in many of the posts about the First World War, which come under Subjects.
