[3] From 1971–88, she worked as a research assistant at the Museum of Art Lucerne with Jean-Christophe Ammann and later with Martin Kunz.
Eigenheer’s work has its roots in drawing, in which the freely moving line precedes the flat, pictorial dimension.
Her drawings are gesticulating, free line works on paper, in which the spontaneous, subconscious action is combined with conscious formal and content-related decision-making.
They are semiabstract forms and “mergers of entirely different beings,”[3] which attain comic-like, erotic associations, symbolic elements and also a great dynamic.
At this time, she also painted large canvases, as part of the series Misere des Herzens (Misery of the Heart), with animal silhouettes, human figures and hybrid beings, who seem to float or lie before monochrome backgrounds.
These include the wall drawings Das Buch der 5 Ringe von Mushahi, 1991, at Kiel Central Station or Les Guédés dansent toujours (2012).
