During the Second World War numerous employees at the Observatory were called up for military service. Many of those who stayed behind because they were too old, too young or were doing work considered essential to the war effort joined the Home Guard. This photograph shows three members of Observatory staff in their Home Guard uniforms.
The Ministry of Agriculture launched the 'Dig for Victory' campaign soon after the outbreak of war. People were encouraged to transform private gardens, parks and scrub land into mini-allotments. It was believed that this would not only provide essential crops for families and neighbourhoods alike, but help the war effort by freeing up valuable space for war materials on merchant shipping convoys. By 1943, over a million tons of vegetables were being grown in gardens and allotments like the ones shown here in Greenwich Park. The National Maritime Museum and Royal Naval College can be seen in the distance.
