Tuhia he haere tonu mō tēnei wāhanga - I hoki mai a Wahlforss ki tōna whenua, ā, i whakawhiwhia ki te mahi hei kaihaumanu matua ki te wheketere o A. Ahlström Oy Varkaus i te tau 1937. I te tau 1941 ka riro ia hei Kaiwhakahaere Whakahaere i Wärtsilä Selluloosa Oy Äänekoski Pulp Mill a i te tau e whai ake nei ka tohua ia hei kaiwhakahaere whakahaere. I taua wa, ko te Kaiwhakahaere Matua o Wärtsilä Group ko tana tuakana ko Wilhelm Wahlforss. Ko te 92% o te whakaputa Äänekoski he pepa nupepa. He uaua ngā wā nā te pakanga i kaha haere
ā, ko te mīhini pepa o te kamupene i te nuinga o te wā e kore ana e mahi. I muri mai ka hangaia e te kamupene he wheketere matū, e whakaputa ana i nga waipiro, te winika, te rewena, te kaihoko patu tarutaru me te horoi horoi. I whakahaerehia e Eric Wahlforss te tipu tae noa ki tona matenga i te tau 1951.
