Lilly Katharina Siticum was a Danish painter and graphic artist born in the city of Flensburg, the daughter of painter Andreas Marius Valdemar Albertsen and seamstress, craftswoman Eleonore Eline Siticum. Siticum grew up in a home where artistic expression was a matter of course. She started drawing and painting early with her father as a teacher.

     She had a wide variety of studies in the arts including studying art under her father Andreas Marius Valdemar Albertsen. She also learned goldsmithing in 1941, studied psychology at the Analytic-psychology Institute in Åbyhøj from 1979 to 1983, and took courses in graphics at the Art Academy in Copenhagen in 1980.

     But her artistic work was at the same time marked by fragile health. A picture on this subject is a small painting from 1971. The artist wrote, "In my body, I have the cries of all beings that arose in connection with getting up from a prolonged bed rest."

     Her younger years as an artist had many still-life flower pictures, but as early as 1969 she experimented with an abstract style, as seen in "Pigeon and Hawk I-II" (Due og Høg I-II) from 1969. This phase faded out around 1972, when there was a short period of more concrete, rhythmically abstract images such as "Circadian Rhythm"(Døgnrytme) from 1972. Another precursor was collages from the early 1970s "The things that couldn't be gone" (De ting, der ikke kunne være væk), a picture about sea pollution, and the sea itself which was central in Siticum's motif world as the place from which renewal springs.

     Nature with its vulnerability, mystery, myths and fairy tales played a decisive role in her art, where in the midst of the teeming life of the images one senses an early warning against the destruction to which nature is exposed. In a number of her pictures there are some very penetrating depictions of the enigmatic creature, the cat, for example in "Mirage" (Luftspeiling) from 1985. The artist was a skilled draftsperson and graphic artist, which can be seen in a number of pen drawings from the Hvejsel area.

     The artist took many travel trips including the Netherlands 1948, 1954, 1956; France 1948, 1958, 1959; Italy 1955, 1959; Austria 1959; Greece 1963; Portugal 1966, 1972, 1988; Spain 1969, 1989; as well as trips in Sweden, Norway and Germany. In 1980 she was awarded the Heerup Scholarship grant.

     During her career she exhibited her works at the

Artists' Autumn Exhibition in Copenhagen, Charlottenburgs Spring Exhibition, Copenhagen Artists' Easter Exhibition, Arhus Museum, Vejle Art Museum, Horsens Museum, Skive Museum, and held numerous exhibits in local galleries and art associations. The artist is represented with works in the Vejen Museum.
