[1] She was one of seven children of merchant Carl Edward Johansson Derkert and Emma Charlotta Valborg, born Fogelin.

[3] Fellow students included Annie Bergman, Elsa Björkman-Goldschmidt, Harriet Löwenhjelm, Ragnhild Nordensten, Gerda Nordling, and Elvi Tondén.

In February 1914, the three friends spent five weeks in Algiers where Derkert was introduced to more vibrant and bolder colour schemes.

[6] Derkert had three children: a son Carlo (1915–1994) with Finnish artist Valle Rosenberg and daughters Liv (1917–38) and Sara (born 1920) with Swedish illustrator Bertil Lybeck.

At this time Russian Ballet had a heavy influence on fashion design and inspired an avant-garde dance show she participated in producing in 1917.

The dance show was produced in a theater in Stockholm known as the Intiman, with the collaboration of the artist Anna Petrus, Märta Kuylenstierna, and her sister Sonja Derkert.

Since the station was designed to serve as a shelter in case of a nuclear war, Derkert filled the walls with messages of peace, feminism and notes from revolutionary songs.

[6] When Apollo 11 landed on the moon in 1969, the Swedish Radio invited some noted Swedes to comment on the event during the broadcast.

Derkert was chosen to speak along with former leader of the Communist Party of Sweden C.-H. Hermansson and archbishop Ruben Josefson.
