[1][2][3] Ahlström was born on 7 November 1827, in Merikarvia, and was a socially active citizen, representing the bourgeoisie of the Town of Pori at the Diet of the Estates in 1877–1878 and in 1894.
One month after the deed of sale was signed, his wife Margaretha died of a sudden illness.
In 1871, Antti Ahlström married again, this time to a woman 20 years his junior, Eva Holmström.
[5] Ahlström's business grew rapidly through major acquisitions, such as the iron works in Kauttua, Leineperi and Strömfors and the sawmills in Haminaholma, Suursaari and Tampere.
When Ahlström died on 10 May 1896, aged 68, in Helsinki, he left behind a fortune estimated at 11.4 million Finnish markkas, which was Finland's largest at the time.
