history we have to start long time ago and
study our ancestors and find the motive that push then to discover this
the beginning, the human kind noticed that staying
close to water was important for them to survive. And the
desire to go under water to supply food, uncover
artifacts, and perhaps just to observe marine life has always existed.
When did man started diving?
diving at least 6500 years ago
and soon the food
was out our reach, there was a desire to go deeper and divers trained
from childhood for lung capacity
water longer the natural way
so the concept of diving was abandoned, Or not mentioned in history until recovering goods from
became a desperate motive to start developing new ideas that will
change the diving history.
Desperate reason and new ideas for
diving bell is one of the earliest
types of equipment
for underwater work and exploration in diving history. Its use was
described by Aristotle "...they enable the divers
respire equally well by letting down a cauldron, for this does not fill
water, but retains the air, for it is forced straight down into the
Even that was
mentioned by Aristotle in 4th century BC, only in
1535, Guglielmo de Lorema created and
used what is
considered to be the first diving bell.
How divers used the diving bell?
divers went out from
the diving bell with their breath held, to do some work under water.
they were out of breath, instead of ascending to the surface, they
to the bell where they inhaled fresh air and return to work. When the
air was finished, the bell had to resurface.
In 1691 - Edmund Halley patented a diving bell method
which air pressure provided from the surface in barrels kept the diving
for longer periods of time.
From the diving bell to the diving suit
Augustus Siebe, a German-born British engineer, developed
the first workable diving suit about 1839. This waterproof suit had a
detachable helmet connected to the surface by a hose through which air
pumped. This kind of tethered suit remained the only practicable diving
until the 1900s.
1900's to modern diving history
1943, Jacques-Yves Cousteau and engineer Émile Gagnan, two Frenchmen
adapted a previously developed breathing apparatus to underwater
use. Their improvement was named the "aqualung, and was a great
and revolutionary invention in diving history. The Aqualung
remained a secret until the South of France was liberated from Germany
at the end of World War II.
