Ina Lange (née Forstén; 14 December 1846 – 23 October 1930), also known by her pen names Daniel Sten and Daniel Stern, was a Finnish writer, music historian, pianist and music instructor.
Early life and education
Ina Forstén was born into an upper-class family in Helsinki. Her father, Johan August Forstén, was a high-ranking civil servant, and her mother Augusta Wilhelmina (née Danielson) was cousin to the senator and professor, Valtioneuvos Johan Richard Danielson-Kalmari. She was second cousin on father’s side to professor G. V. Forsten.
She was privately educated, first at home by a governess, followed by studies at the Höhere Töchterschule (lit. 'Higher Daughter School') in Berlin.
She subsequently went on to study music, first in Berlin, and later at the Moscow Conservatory under the likes of Nikolai Rubinstein and Pyotr Ilyich Tchaikovsky.
Private life
While living in Stockholm in the 1870s, Forstén is known to have been friends with the Finnish noblewoman and actress Siri von Essen and her Swedish writer husband August Strindberg, in many of whose works she appeared.
In 1876, she married the opera singer Algot Lange. The couple had three sons, the youngest of whom, Åke Mortimer (b. 1884), later took his father's name and became known as the explorer and writer Algot Lange.
The Langes lived at first in Helsinki, then Stockholm, before moving in the mid-1880s to Copenhagen. There she became acquainted with Maria Feodorovna (then Princess Dagmar of Denmark) and Crown Prince Frederik. She is known later to have used her friendship with the former to pass on messages between Finnish politicians Danielson-Kalmari and Yrjö Sakari Yrjö-Koskinen and the Russian Imperial Court, to advocate for constitutional reforms in Finland.
