August Macke (3 January 1887 – 26 September 1914) was a German Expressionist painter.
 He was one of the leading members of the German Expressionist group Der Blaue Reiter (The Blue Rider).
 He lived during a particularly innovative time for German art: he saw the development of the main German Expressionist movements as well as the arrival of the successive avant-garde movements which were forming in the rest of Europe.
 Like a true artist of his time, Macke knew how to integrate into his painting the elements of the avant-garde which most interested him.
Vincent Pepi (born 1926 in Boston) is an abstract expressionist painter associated with the New York School.
 His contribution to American art includes some of the foremost examples of action painting, produced consistently over the course of the second half of the 20th century.
 His art parallels the works of Jackson Pollock, Willem de Kooning, Franz Kline, Conrad Marca-Relli and others.
 He adapted the automatic techniques of the Surrealists and transformed it into his own kind of gesture painting.
James Bumgardner (1935 - 2015) was an expressionist/figurative painter, multi-media artist, and stage set designer who was a Virginia Commonwealth University professor of art in the VCU School of the Arts.
 As an undergraduate student at Richmond Professional Institute (RPI), Bumgardner was encouraged by his mentor Jewett Campbell to study with the notable Art Students League of New York instructor Hans Hoffman (1880 – 1966), and Bumgardner received the last scholarship given by Hoffman, a German-born American abstract expressionist painter.
 Using his scholarship, Bumgardner studied with Hoffman in Provincetown in 1957, during which time he became friends with gallery director Richard Bellamy and artist Jan Müller.
 In 1963 in Richmond Jim Bumgardner and Jon Bowie co-directed a series of multi-media events or "happenings".
 The first was called "Synthesis" and was influenced by the productions of Allan Kaprow and the "ONCE Festival of New Music" of Ann Arbor, Michigan.
 After "Synthesis" Bumgardner and Jon Bowie invited notable outside performance and visual artists who joined in a series of annual "Bang, Bang, Bang Arts Festival" happenings in Richmond.
Jacques Herbert Kupfermann (1926–1987) was an American Expressionist painter who was born in Vienna.
 His work, both abstract and figurative, divides into several distinct periods, reflecting both his early influences and later lengthy sojourns in countries as far apart as Mexico and Norway.
 Renowned for his portraits as well as landscapes, his subjects include many eminent figures.
 His distinctive use of impasto, the typically Expressionist love of the paint itself and rich earth colours, are perhaps some of the defining features of his work – as are his love of bleak Northerly scenery, the combination of delicacy and vibrant movement discernible in his still-life subjects, and an aura of tenderness and serenity even where a certain turbulence seems to lurk beneath the surface.
 Though he resisted making any obvious political or sociological statements in his work, it is not difficult to see how his early years in Vienna with all its uncertainty, daily threats and background violence, might have influenced his later paintings.
Natalia Dumitresco (born Natalia Dumitrescu; 1915 in Bucharest, Romania – 1997 in Chars, France) was a French-Romanian abstract painter associated with the "Réalités Nouvelles" salon of Paris after the Second World War, a movement influenced by the art of Wassily Kandinsky and Alberto Magnelli.
 Other abstract expressionist painters associated with the "Réalités Nouvelles" include Serge Poliakoff and Alexandre Istrati.
 Dumitresco later married Alexandre Istrati.
Johannes Itten (11 November 1888 – 25 March 1967) was a Swiss expressionist painter, designer, teacher, writer and theorist associated with the Bauhaus ("Staatliches Bauhaus") school.
 Together with German-American painter Lyonel Feininger and German sculptor Gerhard Marcks, under the direction of German architect Walter Gropius, Itten was part of the core of the Weimar Bauhaus.
Olivia Kapoor is best known as one of the pioneering Visionary Artists within the Inter-Dimensional Art Movement.
 She is an American painter who has exhibited and showcased her work in Paris, London, Amsterdam, New York City, Los Angeles, Miami, Toronto, and Bologna.
Following the teachings of noted 19th and early 20th century faculty from The Bauhaus Modernist Art School, Kapoor continues to examine Wassily Kandinsky’s, Josef Albers’, Laszlo Moholy-Nagy’s, Paul Klee’s, and Johannes Itten’s exploration of the relationship of art, technology, and the universe.
Elaine de Kooning (March 12, 1918 – February 1, 1989) was an Abstract Expressionist and Figurative Expressionist painter in the post-World War II era.
 She wrote extensively on the art of the period and was an editorial associate for "Art News" magazine.
 On December 9, 1943, she married painter Willem de Kooning.
Helen Frankenthaler (December 12, 1928 – December 27, 2011) was an American abstract expressionist painter.
 She was a major contributor to the history of postwar American painting.
 Having exhibited her work for over six decades (early 1950s until 2011), she spanned several generations of abstract painters while continuing to produce vital and ever-changing new work.
 Frankenthaler began exhibiting her large-scale abstract expressionist paintings in contemporary museums and galleries in the early 1950s.
 She was included in the 1964 "Post-Painterly Abstraction" exhibition curated by Clement Greenberg that introduced a newer generation of abstract painting that came to be known as Color Field.
 Born in Manhattan, she was influenced by Greenberg, Hans Hofmann, and Jackson Pollock's paintings.
 Her work has been the subject of several retrospective exhibitions, including a 1989 retrospective at the Museum of Modern Art in New York City, and been exhibited worldwide since the 1950s.
 In 2001, she was awarded the National Medal of Arts.
Gabriele Münter (Berlin, 19 February 1877 – 19 May 1962) was a German expressionist painter who was at the forefront of the Munich avant-garde in the early 20th century.
 A student of the painter Wassily Kandinsky, she was a founding member of the expressionist group "Der Blaue Reiter."
