As an intern with the History Department at Te Papa, I have been given the challenging task of researching the sitters who appear in a number of photographic portraits held in the collection.

Looking closely at some of the pictures, it seems that the images contained on the museum’s glass plate negatives are not all original photographs.  Some were taken in their frames by family members to the premises of Berry & Co. in Wellington for copies to be made.  This would often have happened if the picture had been sent from family members abroad, or if the soldiers pictured had died.

Two of the images which seem to have produced this way were each marked with the handwritten name ‘Jessen’, and although there are sometimes two or three images among the collection with the same sitter, these two were certainly not the same man.

Through using database records and military personnel files, I believe I have identified these two men as brothers John and Donald Jessen.  Both were members of the New Zealand Field Artillery who died while away at war in Europe.

Elder brother John Jessen was born in Mauriceville to parents William August and Christine in the same year as their marriage, 1890.  The family had moved to Wellington by 1908, when John joined the D Battery of the New Zealand Field Artillery Volunteers.  In 1914 he joined the New Zealand Expeditionary Force who departed for Samoa on the 8^th August.  Returning from Samoa on the 22^nd March 1915 he was discharged on his own request and went to work as a clerk in the New Zealand Government Thorndon Railway Station.  On discharge he held the rank of Battery Sergeant Major.

At the end of 1915 John Jessen was among a number of non-commissioned officers called up to join the 14^th reinforcements for the Western Front.  He was killed in action in France during the Battle of Bapaume on the 24^th August 1918, aged 28.  By this point he held the rank of Bombardier and was part of the 9^th Battery.  He is buried in Achiet-le-Grand Communal Cemetery Extension in grave IV.P.3.

Younger brother Donald Jessen worked as a warehouseman in Wellington and also served in the D Battery volunteer force until 1915 when he joined the New Zealand Field Artillery as part of the 10^th reinforcements.  He went into Trentham Camp on the 16^th November 1915 and embarked on the Willochra or Tofua to Egypt on 4^th March 1916.  His unit on embarkation was the No. 5 Field Battery (2^nd Field Artillery Brigade).

Although he survived the war, Donald contracted a bout of influenza in 1919 which became pneumonia, and he died at Endell Street Military Hospital in London on the 23^rd February 1919.  He is buried at Brookwood Military Cemetery, grave reference II.J.4.

Both soldiers were commemorated by their parents and sisters in adverts placed in the Evening Post.  They are just two casualties of an estimated 14,000–17,000 New Zealand citizens who were killed in action or died as a result of their wounds. New Zealand had one of the highest casualty rates as a proportion of the total population of all the countries involved in the war.
