Firefighters did not wear eagles before that, but eagles became associated with fire helmets ever since.
The beaver ornament adorning on many Canadian firefighters' helmets is said to represent firefighters' relentless hard work, focused mission and undying dedication.
A Denver firefighter known as Merriman invented an early hose mask that was featured in the January 7, 1892 issue of Fireman's Herald.
This respirator featured a tube like that of an elephant trunk connected to an air hose that ran parallel to the firefighter's water hose.
However, many firefighters and fire departments still retain the leather helmet as a matter of tradition.
In 1871, British physicist John Tyndall wrote about his new invention, a fireman's respirator, featuring a valve chamber and filter tube.
These ornaments protrude from the helmet and can catch on window sashes, wires and other obstacles, frequently leading to damage.
The device was featured in the July 1875 issue of Manufacturer and Builder.These helmets were modelled on the helmets of the Sapeurs-pompiers which Captain Sir Eyre Massey Shaw had seen on a visit to Paris and introduced to the Metropolitan Fire Brigade in London in 1868, replacing a black leather helmet.The design was widely copied by other British and British Empire fire services.However, during World War II, military-style steel helmets were adopted, similar to the Brodie helmet used by the British Army, to improve protection during air raids.A composite helmet was reintroduced after the end of the war.
