Anna Maria Augusta Cassel (15 March 1860 close to Grythyttan – 18 February 1937 in Stockholm) was a Swedish artist.
[3] The two first met in 1878 when Cassel started studying at Slöjdskolan, the year before it changed name to Tekniska skolan (now called Konstfack).
Anna Cassel was a member of the Edelweiss Society at the same time as Hilma af Klint.
Through their spiritual guidance, the group was inspired to draw automatically in pencil, a technique that was not unusual at that time.
When the hand moved automatically, the conscious will did not direct the pattern that developed on the paper, and, in theory, the women thus became artistic tools for their spirit leaders.
In a series of sketchbooks, religious scenes and symbols were depicted in drawings made by the group collectively.
