Madvig learned to draw with the painter and illustrator Carl Thomsen, and then to model with professor August Saabye, with whom she worked for four to five years. In 1892, she exhibited at the annual Charlottenborg Spring Exhibition her first piece, En kvinde, and in 1893 Sovende barn. Later, modeled a body-sized figure, called Asra and some busts, among others, one of her sister Jenny, who was married to the painter Georg Seligmann.
Madvig also played music and gave concerts in Paris, where she lived from 1903 until shortly before her death.
Madvig used especially family members as models, but also famous people, both contemporaries, like professor Julius Petersen, and deceased, such as the composer Frédéric Chopin. As a sculptor, she was a naturalist, while her painting was mostly influenced by French Impressionism.
