Here's what we know:
* He was a chemist at Fleer. While his role in the company isn't specifically detailed, it's likely he had a background in chemistry.
* He created a gum that wouldn't stick to machinery. This was a significant challenge in the early days of gum production.
* The initial "bubble gum" wasn't very good. It was initially quite brittle and didn't make good bubbles. He continued experimenting until he found the right combination of ingredients to create a gum that was both chewy and bubble-forming.
There's a lot of information about Walter Diemer's contribution to bubble gum, but not much about his life or career outside of that invention.
It's worth noting that:
* He did not invent chewing gum. Chewing gum has been around for centuries, and modern chewing gum existed long before Diemer's invention.
* His discovery of bubble gum was accidental. He initially tried to create a gum that wouldn't stick to machinery, but it turned out to be perfect for blowing bubbles.
Overall, Walter Diemer's legacy is tied to his accidental invention of bubble gum, which has since become a popular treat worldwide. However, there's still much that's unknown about his life and accomplishments beyond that.
