There are quite a few possibilities for this. Most likely in my opinion is engineer Paul Cope who worked for Proctor and Gamble in the 1940's. George Schultz invented a type of industrial glue gun but much later.

You can glue things faster and more easily with a glue gun than with a tube of glue (although I still use tubes, personally).
No, you cannot use a solder gun as a hot glue gun.No, you cannot use a solder gun as a hot glue gun.
Turn the glue gun on to loosen the glue, then, if the glue is persistent, use a wooden stick to CAREFULLY pick the glue off.

Glue stick.
No it is not.
Hot glue has been used for many centuries, the first hot glue was made by finely grating animal hooves together with a mineral spirit and heated in a double boiler, when soft it was used to glue wood and other porous materials. the glue gun was a natural evolution from the double boiler, it has made the use of hot glue very easy and quick. by the way, they make use of synthetic glue and no longer use animal hooves.
Dr. Harry Coover invented super glue
Glue guns are designed to heat up hot glue for craft projects. The glue gun warms up special glue sticks, and makes it easier to apply this glue to the right place in the projects.
Yes, you do need a hot glue gun, it's the only safe way.
