Obituary: Professor Pentti Matti Sakari Lackman shattered taboo truths

Professor Pentti Matti Sakari Lackman, a historian who fearlessly challenged conventional historical narratives, died suddenly on April 21, 2026, at the age of 78. Born in Simo on February 24, 1948, Lackman grew up on a farmer's family but was drawn to history after initially aspiring to be an artist.

Lackman's academic career included becoming a history teacher and later the rector of the Oulu Workers' Institute, which he led with a distinctive style until his retirement in 2013. Alongside his primary work, he was deeply involved in the Oulu Historical Society, serving as its long-time leader and contributing to its popular lecture series and publications. His engaging speaking style and dedication fostered strong collegial relationships, extending his influence to various other societies in Oulu and beyond.

His doctoral dissertation in 1985 marked the beginning of his reputation for bold research. Lackman is particularly noted for his work on the Jäger Movement, where he "shattered truths considered taboo." This courage extended to his research on the Finnish Civil War, peasant uprisings, and other historical subjects. He consistently defended the freedom of research, emphasized archival work, and contributed numerous reviews to newspapers.

In recognition of his scholarly achievements, Lackman was awarded the title of professor in 2008 and served as a docent in Finnish and political history at universities in Oulu, Eastern Finland, and Turku. He was known for his motto, derived from an old Roman saying: "lingua haeret metu" – fear paralyzes the tongue. His friends and colleagues remember him as a researcher who bravely pursued truth without compromise. He is survived by his wife, Eija, and their three daughters.
