As the brewery fell on hard times in the 1940s their Souvenir brand became the top seller and Grossvater became an aged and outdated relic. Despite a repackaging of their staple brew sales continued to fall and the brewery ceased operations on December 8, 1952 and closed the plant for good 6 weeks later after dispensing of the last cases of beer. I'm guessing that ads like the following didn't help their cause.

The company itself survives as the Renner Akron Ralty Co. which had been a branch of the corporation since before Prohibition. According to this informative site much of the brewery still stands as well.
This is another beer and company that I'd never heard of and probably never would have if it wasn't on the same page as a Tech Beer ad. Apparently Tech's market reached into Ohio and Pittsburgh Brewing Company's longevity probably played into the demise of both Grossvater and Renner.
