Marr was commissioned to work on the graves project by the New Zealand Government. He lived in a small house on the peninsula for three years until the work was complete. "Living there, he had a real feeling for those men, that's why he spent so much time there and put in so much effort," his grandson Bill Marr told the Herald. "Grandad was meticulous. He would have done all the 21 cemeteries, him and a guy from Tasmania. They designed them and supervised them being built."
Edmund Marr never spoke much of his time at Gallipoli, despite not being there for the campaign in which New Zealand lost almost 3000 men. "I think he was distressed at the needless deaths. It overcame him," Bill Marr said. "The braveness of the lads, that's totally undisputed. They were incredibly brave - what they did was amazing."
Gallipoli historian and author Ian McGibbon explained how the memorials were designed.
"Built in the form of an enclosure containing the graves, each cemetery has a monument, the size of which depends on the number of graves buried within it. These monuments are building the style of a mural cross, with the cross projecting from a higher central structure. In the larger cemeteries a great stone of remembrance is set in front of the monument."
