Ovartaci was the artistic name of the Danish visual artist Louis Marcussen (1894 – 1985).
Ovartaci was committed to the Risskov psychiatric hospital in 1929.
She then had a sex change operation in 1957.
She lived and worked in the institution for fifty-six years.Ovartaci's phantasmagoric work features numerous female and animal figures set within an abundance of symbols, interiors, and landscapes.
These figures are invested with a sense of identification that seems to defy the divide between real life and the realm of art.
In 2018 an expansive exhibition entitled "Ovartaci and the Art of Madness" included a survey of the artist's work, as well as homages and related works by contemporary artists.
