Who invented Charmglow gas grills?

The outdoor gas grill was invented in the early 1950s by Don McGlaughlin, owner of the Chicago Combustion Corporation, known today as LazyMan.

McGlaughlin invented the first built-in grill from the successful gas broiler called BROILBURGER. These first Lazy-Man grills were marketed as "open-fire charcoal-type gas broilers" which featured "permanent coals", otherwise known as lava rock. In the 1950s, most residential households did not have a barbecue, so the term broiler was used for marketing purposes to commercial establishments.
