History
Doka, undasch The Store Makers and undasch Industrial Solutions make up the Umdasch Group AG with its headquarters located in Amstetten, Austria. In 1868 Stefan Hopferwieser founded the company St. & A. Hopferwieser as a carpenter in the town of Kollmitzberg. During the first 80 years of the company, the company had diversified into carpentry, sawmill wood and metal manufacturing, producing among others furniture, home appliances, metal hardware and packaging. In 1949, the engineer Josef Umdasch, who was married to Mathilde Hopferwieser (granddaughter of Stefan Hopferwieser) became the managing director of the company rebuilding and restructuring it. Josef Umdasch had been a board member of the company since 1939.

Why this record matters
The phrase “company” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The record creator and administrative purpose are central evidence, because official documentation reflects both action and institutional priorities. The source revision retrieved here is dated Jul 17, 2026. The linked authority identifier is Q634672. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2025, 1868, 1949 and 1939.
Official terminology may obscure informal participation, dissent or communities documented only indirectly. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
