Expressionism is a form of art that expresses an experience rather than the actual object. This movement is thought to have started as early as 1850 but did not get popular until the early 1900's. This movement started as a response to the major changes in the atmosphere of society. A few artists that are well known in this era are Edward Munch and Gustav Klimt.
In current times the expressionist works of Siri Beckman are well known. Over the time period of expressionism it hasn't changed much and Siri Beckman's work is alike to that of Kathe Kollowitz. Both of their styles in ink and engraving are very similar.
