Forsström worked as Lohjan Kalkkitehdas Oy's (Lohja Lime Factory Ltd) managing director for an exceptionally long period of time, 65 years.
[2] In 1946 he was sentenced to six years in prison for treason after participating in the pro-German resistance movement during the Lapland War, after the Finnish government had switched sides.
Forsström served as the managing director of Lohjan Kalkkitehdas Oy, founded by his father, for a record long period, from 1897 to 1962.
[5] Unlike several other entrepreneurs and business leaders for whom the Lapua movement's achievements in defeating communism were sufficient, Forsström subsequently expressed even more radical far-right views.
[5] In the early 1940s, Forsström described his company Lohjan Kalkkitehdas Oy as “a national socialist community in the middle of a liberal democratic system”.
[8] Following the revelation of the organisation, Forsström received a six-year sentence, half of which he served and was stripped of his "civic confidence" (kansalaisluottamus) and deprived of his right to take part in the political process after his release.
