Background

At the outbreak of
World War I
World War I or the First World War (28 July 1914 – 11 November 1918), also known as the Great War, was a World war, global conflict between two coalitions: the Allies of World War I, Allies (or Entente) and the Central Powers. Fighting to ...
, none of the combatants provided their troops with steel helmets. Soldiers of most nations went into battle wearing cloth, felt or leather headgear that offered no protection from modern weapons.
A significant partial exception to this lack was the German
''Pickelhaube''. Like other army helmets of 1914, it was made out of leather; but it also had a significant number of steel inserts, which offered some head protection. This included the top spike, originally used to stop strikes from an enemy hand-held sabre.
The huge number of lethal head wounds that modern artillery weapons inflicted upon the

led them to introduce the first modern steel helmets in the summer of 1915. The first French helmets were bowl-shaped steel skullcaps worn under the cloth caps. These rudimentary helmets were soon replaced by the Model 1915
Adrian helmet, designed by
August-Louis Adrian. The idea was later adopted by most other combatant nations.

had seen a similar need for steel helmets. The War Office Invention Department was ordered to evaluate the French design. They decided that it was not strong enough and too complex to be swiftly manufactured. British industry was not geared up for an all-out effort of war production in the early days of World War I, which also led to the
shell shortage of 1915.

but was working in London at that time. A design patented by him in August 1915 offered advantages over the French helmet. It was constructed in one piece that could be pressed from a single thick sheet of steel, giving it added strength and making it simple to manufacture. Brodie's patent deals mainly with the innovative lining arrangements; an engineer called Alfred Bates of the firm of Willis & Bates of
Halifax, Yorkshire, manufacturer of
Vapalux paraffin pressure lamps, claimed that he was asked by the War Office to find a method of manufacturing an anti-shrapnel helmet and that it was he who had devised the basic shape of the steel shell; some newspaper articles are the only evidence for this claim.
Brodie's helmet resembled designs from past eras, in particular the medieval infantry

projectiles bursting from above the trenches. The design allowed the use of relatively thick steel that could be formed in a single pressing while maintaining the helmet's thickness. This made it more resistant to projectiles but it offered less protection to the lower head and neck than other helmets.
The original design (Type A) was made of

Robert Hadfield to a harder steel with 12%

Hadfield steel and was virtually impervious to shrapnel hitting from above. Ballistically, this updated specification increased protection for the wearer by 10%. It also had a narrower brim and a more domed crown.

The original paint scheme, suggested by Brodie, was a mottled light green, blue and orange camouflage but they were also painted in green or blue-grey.

troops took place in September 1915, at the rate of 50 per battalion. Initially, there were far from enough helmets to equip every man, so they were designated as trench stores, to be kept in the front line and used by each unit that occupied the sector. By early 1916, about a quarter of a million had been made, and the first action in which the Brodie was worn by all ranks was the
Battle of St Eloi, in April.
Although the helmet's benefits were recognised, there was criticism from several quarters, including
General Herbert Plumer, who said that the helmet was too shallow and too light-reflective, its rim was too sharp, and its lining was too slippery. It was decided to introduce a number of improvements, and from May supplies of the modified helmet, designated the Mark I, began to arrive. It had a separate folded rim, a two-part liner, and matte
khaki paint finished with sand, sawdust, or crushed cork to give a dull, non-reflective appearance.

By the summer of 1916 the first million helmets had been produced, and they were issued to all troops.

Variants
United Kingdom
*Brodie's Steel Helmet, War Office Pattern, Type A: the original 1915 helmet with the shell made from magnetic mild steel.
*Brodie's Steel Helmet, Type B: with the shell made from Hadfield (manganese) steel.
*Helmet, Steel, Mark I: introduced in Spring, 1916, a modified version of the Brodie helmet with a wholly redesigned liner and a mild steel rim to the shell. In 1917, a rubber ring or "doughnut" was added between the liner and the top of the shell, and in 1935, the liner and chinstrap were modified to make them removable.
*Helmet, Steel, Mark I*: introduced in 1938 and made up from old Mark I shells, but fitted with an all new liner and chinstrap. This was the standard British Army helmet at the start of the Second World War.
*Helmet, Steel, Mark II: also introduced in 1938, the Mark II featured a new shell with a non-magnetic rim (so that the wearer could use a magnetic compass

) and the new liner and chinstrap used in the Mark I*. Early production went to the ARP services, the fire brigade and the police. It was re-designated in July 1940 as the Helmet, Steel, Mark II, No 1 and in the following year, as the Helmet, Steel, No 1, Mark 1.
*Helmet, Steel, Mark II, No 2: by July 1940, it had been realised that demand for the Mark II helmet could not be met, and so helmets which had either been rejected as substandard, or had been newly manufactured from cheaper mild steel, began to be issued under the designation "Mark II, No 2" to the Home Guard and civilian services. These helmets were marked with between one and four small holes drilled into the rim, showing the level of protection that they would provide. This type of helmet was re-designated in 1941 as the Helmet, Steel, No 2, Mark 1.
*Helmet, Steel, Civilian, Civilian Protective Helmet or Zuckerman helmet: when it was found that a large number of civilians were needed to keep a lookout for fires started by incendiary bomb

(an early form of plastic), and offered little protection to the wearer.
Australia
*Helmet No 1, Mark II: a 1936 proposal that steel helmets should be manufactured in Australia was put into effect in 1939 by The Commonwealth Steel Company. The helmets were copies of the British Mark II but lacked the rim. More than two million were produced.
Belgium
*M1949: a post-war Belgian-made copy of the Mark II helmet. The shell was identical to the British original, except that the liner fixing screw on the crown sat in a small indentation. The liner was of Belgian design and the chinstrap was copied from the British Mark III helmet.
Canada
*Helmet, Steel, Mark II: having purchased British helmets in the First World War and at the outbreak of the Second, Canadian helmet production commenced in 1940. The helmets were identical to the British original, except that the rubber "bumper" pads in the lining were only fitted to horizontal helmet band and not to the vertical bands. The Mark II continued in front-line service with Canadian forces until March 1960.
New Zealand
*Helmet, Steel, Mark II: in 1940, an order for 30,000 steel helmets could not be fulfilled by the United Kingdom, so production commenced in New Zealand. Manufactured by General Motors New Zealand and the New Zealand Railway Workshops using presses and sheet steel imported from Australia, 54,000 Mark II had been made by 1942 with Australian and British liners. Surplus helmets were supplied to other Commonwealth and Empire armies.
Portugal
*M1916: on Portugal's entry into the First World War in 1916, the country lacked the facilities to produce its own helmets and looked to the United Kingdom. British helmet production at that time was giving priority to their own forces, however the Director of Munitions Supply was able to source a commercially produced version of the Brodie helmet, originally intended to be sold to British officers at the time when helmets were in short supply. Given the Portuguese designation "M1916", it equipped the Portuguese Expeditionary Corps

. Made of thin-gauge steel, the bowl was fluted in an attempt to add strength. However, the fluting actually increased the chances of penetration if a missile hit one of the ridges, so some M1916s were produced with a plain bowl. A simple liner was laced to the solid shell through a series of holes.
*M1917: the Portuguese designation for the Mark I helmet, which was supplied as soon as the British production facilities became available.
*M1917/30: in 1930, the M1917 helmets were refurbished with a redesigned leather liner.
South Africa

s in the Second World War, South Africa began to produce copies of the Mark II helmet when they became unobtainable from the United Kingdom. Manufactured by the Transvaal Steel Pressing Syndicate, some one and a half million helmets were produced. Unlike the British Mark II and other copies, the plan of the South African helmets was almost circular rather than oval. Another distinguishing feature was three small holes punched into the rear section of the brim, probably intended to allow the fitting of a neck curtain in hot climates. Surplus South African helmets were supplied to other Allied armies.
United States
*M1917: initially the United States purchased 400,000 British Mark I helmets to equip the American Expeditionary Forces
The American Expeditionary Forces (AEF) was a formation of the United States Armed Forces on the Western Front (World War I), Western Front during World War I, composed mostly of units from the United States Army, U.S. Army. The AEF was establis ...
in 1917, and those units which were to integrate with French formations were provided with Adrian helmets. The first US-made copies of the Mark I were supplied before the end of 1917 and some 2,700,000 had been made by the end of the war. The M1917 differed little from the British original; different rivets were used to secure the liner, the wire loop onto which the chinstrap was fixed was thicker and the rubber "doughnut" pad was not adopted. However, the US manufacturers were able to produce a shell with better ballistic protection than the original.
*M1917A1: a redesigned liner and a new webbing chinstrap were approved for service in 1934. This model went into full production in 1941, when 904,020 were produced.
*M1917 Civil Defense Helmet: this helmet was produced to equip the Civil Defense Corps at the start of the war, and differed from the standard helmet in having a simplified liner and thin webbing chinstrap.
