Unica Bachmann-Calcoen studied from 1922 to 1924 at the Rijksakademie van beeldende kunsten in Amsterdam and then became a student of Marie de Jonge (1872–1951) in Laren and from 1924 to 1928 of Martin Monnickendam (1874–1943) in Amsterdam.
After a study trip to Italy in 1928 , she visited the Atelier Grande Chaumière and that of André Lhote in Paris in 1929 . Further study visits took her to Florence , Munich , Amsterdam and Oberstdorf im Allgäu .
Her favorite subjects were portrait and landscape painting and especially depictions of animals with horses and riding scenes as well as free compositions. Committed to a realistic style of painting, she preferred a loose style of painting with a condensed composition.
Unica Calcoen was married to the lawyer Otto Bachmann since 1935.
