Annie Wallén was a photographer who ran her own atelier. She was given the position of trust as the photographer to document in photographs the renovation of the Trollhätte Canal in 1910–1916.

Annie Wallén was born in 1880 in Vallsjö in the province of Småland. Her father was Isak Göransson from Hellinge, a tradesman. Her mother was Hedvig Kristina Agnes Eklasine Ek from Näsby near Vetlanda in the same province. Annie Wallén did not grow up with her biological parents but was placed instead in a foster home, the home of the apothecary Oskar Wallén. It became a family relationship that lasted all her life. Her name was originally Hanna Linnéa Göransson, so both her first name Annie and the surname Wallén are taken later on, in about 1889.

At the beginning of 1910, Annie Wallén moved to Trollhättan where she took over the photography enterprise at E. Jacobson Fotoateljé. The studion was run by Emelie Jacobson at Föreningsgatan 9B. The atelier was later renamed Anne Wallén Fotografiatelier and moved to Torggatan in 1913.

The same year as her move to Trollhättan, Annie Wallén received the assignment from Kungliga Vattenfallsstyrelsen to document the work of renovating the canal and lock section. The greater part of the photographs are taken in the area around Trollhättan and Vänersborg. Apart from being out in the field documenting the work on the canal, Annie Wallén also took care of the studio and took among other things photographs for visiting cards, a popular type of photo with its origins in France. It was modern to take portrait photographs and reproduce them in larger numbers. These visiting cards were then originally left on visits to finer families.

In 1930, Annie Wallén handed over her photography atelier in Trollhättan and moved instead to Halmstad. One year later, in 1931, Annie Wallén died of a cancer-related illness. She was buried in Västra Tunhem in the Vänersborg municipal district.
