Scientific Advancment possible through Mid Century Wershian invention

Date Created: Development period started on January 18th, 1899, and finished on July 7th, 1909.

Invention: Deepwater cold suit inner layer, outer layer, and metallic exolayer, for use with deep sea diving suits of the time, however was revised into a more modern form by Ancesters when Diving gear underwent changes in the late 1970's and 80's

Inventor: Dr. Heynlee Jacobson (1980's revisor is an ancestor, one Kenway Harding)

Country or Region of Origin: South-Eastern Wersh, near Corlabelm

Description: A series of insulative layers for use with deep sea diving, designed to keep water out and heat in. Seen as the first iteration of the dry suit, although it was meant for use with the metallic overskin prevalent at the time of invention.

A modernized version was made and patented with Wershian patent #1763- BC784 "Polar Skin^TM" for use with

Story:

Dr. Jacobson paced his office, cursing his luck with the damnable oceans in the ports of the nearby capital. It would be a simple enough job of they were further south, but the ice cold conditions of the waters surrounding the port and the depth of the water makes using divers to clean the bottoms of the boats so much more dangerous. The water was cold, dangerously so, sitting at a frigid 0*f when the winters set in, making the possibility of figer loss or even death from exposure a high probability.

Just recently the Dr. had gotten told several of the young men in the ports service had come down with hypothermia, and his son numbeted among them. In a not so rare fit of anger, Dr. Jacobson quickly went to the port office and borrowed a diving suit, and set about designing something to defend the many youngsters. He tested various methods, from having warm water pumped into the suit minus the helmet, which actually made it to the final design, but by itself just lead to worse exposure when leaving the suit.
He then tried a strange attempt with a layer of waterproof rubber lining the interior of sailcloth made into a skintight suit that was put on before the metal and burlap oversuit, that when paired with the warm water being pumped into and out of the suit allowed for longer, safer dives, that could even go further into the depths as the elements were no longer a major concern.

Dr. Jacobson quickly set about getting as many of these "dry skin suits" as he could, which meant bringing the plans to a nearby seamstress shop for assembly. Whioe he osnt as well known today and his invention has undergone several changes since the initial model, his design has allowed free diving enthusiasts and deep sea explorers the freedom to adventure without fearing exposure and death or limb loss in response.

Romanoddle Republic, this is for possible entry into your technology timeline, as this invention set groundwork for military armor advancement and actually is important beyond sea exploration
