Ebba Maria Lovisa "Mia" Leche Löfgren (10 October 1878 – 8 April 1966) was a Swedish journalist, writer and peace activist, known for her strong stance against National Socialism and anti-Semitism as well as her involvement in refugee aid and humanitarian relief.

[1] The family's social networks were progressive and liberal, spanning academics as well as educators, cultural intellectuals and politicians, and leaving Leche Löfgren, her younger sister and several brothers many freedoms during their childhood.

[9] Back at home she wrote an anti-militarist article that she sent anonymously to Illustreradt Hvad Nytt, apparently in error as this conservative newspaper did not really align with her political convictions.

[2][11] From 1906 to 1908, she was employed by the conservative newspaper Vårt land as a writer of book reviews for literature that the journal's chief literary critic, Carl David af Wirsén, was not interested in, especially works written by and for women.

From 1916, she also began to write columns for Göteborgs Handels- och Sjöfarts-Tidning, whose editor-in-chief Torgny Segerstedt she already knew from previous work at the liberal periodical Forum in Stockholm.

[1][3] In the following years she continued to publish a series of autobiographical books in a style that mixed literary prose with subjective social commentary, including her insights of political and societal developments as well as portraits of friends, family members, her husband Eliel Löfgren and her role as a woman, wife and mother: Våra föräldras värld (The World of Our Parents), 1934, Så var det då 1900–1940 (It Was Like This 1900–1940), 1941, Hård tid (Hard Times), 1946, Ideal och människor (Ideals and People), 1952, Upplevt (Experienced), 1958, and Bokslut (Closure), 1962.

She increased her writing activities for Göteborgs Handels- och Sjöfarts-Tidning, taking on a decidedly anti-Nazist stance and quickly developing into one of the most prominent political voices of the paper.

[2] Following the death of her husband in 1940, Leche Löfgren decided to move to Gothenburg to better work with Torgny Segerstedt on the issue of Nazism and the persecution of Jews, journalists and other critical voices in the German Reich.

"Jag var naturligtvis i största allmänhet kvinnosakskvinna, som alla liberala kvinnor var på den tiden", men sådana rösträttspionjärer som Ann-Margret Holmgren, Karolina Widerström, Gerda Hallberg, Lydia Wahlström, Anna Bugge-Wicksell, Gulli Petrini och Signe Bergman tillhörde en något äldre generation än min.

However, the organization dissolved in 1940, amid an increasing influx of refugees from Germany as well as the occupied territories in Denmark, Norway, Poland and other countries, due to a lack of funding and problems in collecting sufficient donations from the general population.

[3][7] Leaving a rich legacy behind as one of the leading voices in Swedish peace activism during the first half of the 20th century, Leche Löfgren spent her last years in Stockholm until her death in 1966.
