If "Google is your friend," then Wikipedia is your mom:

Although the article doesn't answer your question (just like ma).

Drywall was first patented in 1917 by the USGypsum company.

From their website:

The company patented the world's first drywall panel - the
SHEETROCK Brand panel - in 1917. Following years of
refinement, these gypsum panels revolutionized home building
techniques during the 1940s and 1950s by providing an
economical alternative to conventional plaster wall
construction. Their development enabled builders to meet an
unprecedented demand for new, affordable homes during the
post-World War II housing boom.

During the 30's, salesmen would drive around to job sites with a sheet
tied to the roof of their car to show the durability of the panel. I
wouldn't want to do that now. I wonder how much the
formulation/fabrication has changed over the years... I'm sure the
paper facing has gotten thinner.
