Oswald Achenbach was a German painter associated with the Düsseldorf school of painting. Though little known today, during his lifetime he was counted among the most important landscape painters of Europe. Through his teaching activities, he influenced the Kunstakademie Düsseldorf. His brother, Andreas Achenbach, who was twelve years older, was also among the most important German landscape painters of the 19th century. The two brothers were humorously called "the A and O of Landscapes" (a reference to their initials matching a common German reference to the Alpha and Omega).
Artemisia Gentileschi was an Italian Baroque painter. Gentileschi is considered among the most accomplished seventeenth-century artists, initially working in the style of Caravaggio. She was producing professional work by the age of 15. In an era when women had few opportunities to pursue artistic training or work as professional artists, Gentileschi was the first woman to become a member of the Accademia di Arte del Disegno in Florence and she had an international clientele.
Many of Gentileschi's paintings feature women from myths, allegories, and the Bible, including victims, suicides, and warriors. Some of her best known subjects are Susanna and the Elders (particularly the 1610 version in Pommersfelden), Judith Slaying Holofernes (her 1614–1620 version is in the Uffizi gallery), and Judith and Her Maidservant (her version of 1625 is in the Detroit Institute of Arts).
She is now regarded as one of the most progressive and expressive painters of her generation, with the recognition of her talents exemplified by major exhibitions at internationally esteemed fine art institutions, such as the National Gallery in London.
