World War One
For the firm, World War One was, like for almost everyone in Europe, a significant turning point. Reflecting the inexorable changes that the country went through, never again would the firm scale the heights seen in the preceding few decades.
Indeed, such was the change that the firm appeared to revise their business model, placing more emphasis on the foundry and engineering side of the business. This change, which was probably seen at the time as more of subtly rather than fundamental, probably lead the firm in a direction that eventually caused their demise, albeit some sixty years later.
