Griswold’s founder was born in 1865. Wagner bought Griswold — they knew they couldn’t compete and had to buy the best.
That's nice. It's also irrelevant.
Wagner started operations in 1891. It had nothing to do with "knowing they couldn't compete" (that's silly) or with buying anybody. Your statement is completely counterfactual.
Wagner and Griswold were both bought by an auto-parts conglomerate in 1957 ... when the whole cast-iron cookware market was collapsing. It wasn't "Modern" enough.
Please get your facts straight.
