Heikki Nurminen, who developed Finland's paper industry, dies at 94

Heikki Nurminen, a distinguished chemical engineer and a pivotal figure in Finland's paper industry, passed away on May 9, 2026, at the age of 94. Born in Jokioinen on April 15, 1932, Nurminen's career was marked by significant contributions to the development and expansion of paper manufacturing in Finland.

After completing his military service and graduating with a degree in paper technology from the Technical University of Helsinki in 1960, Nurminen began his professional journey at Enso-Gutzeit Oy's Summa mill. His career took a transformative turn in 1966 when he was recruited to establish the paper industry for Rauma-Repola Oy in Rauma. As the first employee and chief engineer, he faced the challenging task of selecting production factors for a new facility.

Nurminen successfully oversaw the launch of Rauma-Repola Oy's first paper machine, PK 1, in June 1969, which was then the world's widest. Two more paper machines followed in 1971 and 1980, each producing different paper grades. Under his leadership, the Rauma paper mill evolved into a world-leading facility. By the time Nurminen retired in 1990, the mill's annual production had surged from 140,000 tons in 1970 to nearly 500,000 tons.

Throughout his career, Nurminen held various titles, including chief engineer, mill manager, deputy director of the industrial group, and finally, development director from 1985. In this last role, he was responsible for identifying and evaluating potential paper mills for investment by Rauma-Repola Oy, including the St. Mary's paper mill in Sault Ste. Marie, Canada, where he served on the board. Nurminen's legacy extends beyond his direct roles; he is remembered as a pioneer who significantly influenced the rise and development of the entire Finnish paper industry. His service was recognized with the Central Chamber of Commerce's 20-year service medal and the Knight of the Order of the Lion of Finland by the President in 1985. He also actively participated in local civic duties in Rauma.
