Johan Fredrik Aminoff

[1][2] He was born into the Aminoff noble family, which traced its roots to the Holy Roman Empire and Russia.

King Gustav III advanced Aminoff to the position of Colonel and Commander of the Pori County Regiment.

[1][2] King Gustav IV Adolf reached adulthood in 1796 and subsequently granted Aminoff his freedom, honor, titles, and fortunes.

[1][2] The new main building at Riilahti Manor was constructed between 1803 and 1806 by architect Pehr Granstedt, who later designed the Imperial Palace in Helsinki.

Aminoff, Gabriel von Bonsdorff, and Johan Albrecht Ehrenström were involved in the design process of the new main building and the new English landscape garden that surrounds it.

Aminoff was appointed to Count Wilhelm Mauritz Klingspor's army headquarters as Chief of Staff and Advisor.

[1][2] After the Kainuu armistice agreement in March 1809 between Sweden and Russia, Aminoff returned to his Riilahti Manor in Bromarv, Finland.

[1][2] In 1810, Aminoff led a Finnish officer delegation to meet with the Emperor of Russia, Grand Duke of Finland, Alexander I in Saint Petersburg.

Aminoff negotiated an agreement with the Emperor that allowed Finnish officers, the majority of whom were members of the nobility, to retain their salaries and estates.

[1][2] In 1811, Emperor Alexander I invited Aminoff to become a member of the Committee for Finnish Affairs in Saint Petersburg.

The Great Fire of Turku occurred in September 1827, and Aminoff retired from his position in December of the same year.
