" Helmet, Brodie Mark I, on 1916 ".
When the first conflict world sank into a trench warfare, which is indeed led with missiles to dispersal shells of shrapnells etc, three quarters of the wounded persons wore hurts in the head, among which 88 % were mortal.
It is thus for that reason that the French estate management created the first modern helmet in 1915: the helmet Adrian model 15.
With the arrival of the helmet Adrian on the heads of the French soldiers in June , 1915, drew the attention of a special commission, which decided to order 495 copies, which will be delivered in 1st, 2nd and 3rd british army as experiment.
In spite of favorable notices on the ground, the helmet Adrian was rejected by "War Office" of London for an ineffective protection and a too complex manufacturing.
It is thus during this period of search for a helmet for the British strengths, that the engineer John Leopold Brodie proposed his patent of helmet of manufacturing simple and protecting enough the head as well as the shoulders of a soldier in position in a trench.
The liner is unfortunately missing.
