One man invented Band-Aids, granola bars, plastic ketchup bottles, microwaveable containers and disposable diapers!
His name is Stanley Mason and he died in 2006 at 84-years old. In his long and productive career, he had over 60 US-patents under his name. The most impressive thing is that they are things extremely varied in nature. In his career he worked as a professional inventor, working with many corporate clients to create products.
Some credit his success to his process. Before he even starts designing an invention, he first discovers the need for a product. If he realizes that there are many people who would buy his invention; then he spends time inventing it. This process led him to invent things as varied as band-aids, granola bars, and even plastic wire bras!
