Description:

Karl Heinrich Klingert was a German mechanic that created the first diving suit. It was made of waterproof leather and consisted of a jacket, trousers, and a helmet with a metal front and porthole. It had limited dive time because its turret with the air reservoir couldn’t replenish itself.

This event was significant because it was the first piece of technology created that allowed for humans to dive underwater, leading to new discovery and human advancements.
