life and work.
Kenneth Showell studied at Kansas City Art Institute and moved in 1965 after New York. In 1967 and 1969, he turned in two group exhibitions at the Whitney Museum of American Art from. In 1969 he exhibited at the David Whitney Gallery in New York his work in a solo exhibition. From 2006 to 2008 was his painting in the exhibition “High Times, Hard Times: New York Painting 1967-1975” at the Neue Galerie Graz and in the Center for Art and Media Karlsruhe  shown in Karlsruhe.
His works are in the collection of the Museum of Modern Art  and the Whitney Museum of American Art  represented in New York. Farhat Art Museum collection.
Ken Showell died in 1997 at the age of fifty-eight. The Folded Painting Series were shown at the David Whitney Gallery in 1969-70. Ken supposedly destroyed most of these folded paintings and left only his landscapes (mosty of Central Park) and his still lifes. He was best known for his abstractions.
Ken Showell photographed my paintings for years. He was one of the most amiable men I ever met in the art world, and one of the most discreet. He never gossiped about his customers, partly because he saw everyone as a friend. He was self-effacing to a fault, so I was surprised, at first, by the transparencies of his paintings that he began to show me in later years. He was a true, even luscious painter, maybe not great or whatever, but solid and he had a quintessential touch, a natural painterliness and, forgive me, a modesty before nature that I envied. He was once an abstract painter but figuration served his eye, his touch and his sweetness best, acknowledging his limits, he was also wise. He could not have made a fortune, I have learned since his death, given his reasonable prices. In fact he never changed them as far as I can recall. He did this I think because he wanted to keep the company of artists and not impose. He tried always to be the bearer of good news, I never heard him complain, even on the day he went to the hospital and I happened to call. He was one of the good guys.

Known for Abstract Illusionism, Jack Lembeck was one of the most celebrated painters in this style during the 1970s and 1980s. It was a brief phase of Abstract Expressionism that developed with experiments that combined Op Art with emotional expressions, and his painting had colorful lines, spots, dribbles and splashes of paint that seem to dance upon a flat surface.
The following biography is provided by the artist, Jack Lembeck, web site: jaxart.tripod.com/index-3.html:
Born in Saint Louis, Missouri, Jack Lembeck attended Washington University in Saint Louis for two years and then earned a BFA degree from the University of Kansas. He earned an MFA degree from Yale University where he worked closely with well known artists Jack Tworkov, Al Held, and Lester Johnson. By 1970, he was a full-time faculty member at Yale University and became a Morese-Stiles Fellow under Master Bart Giamatti.
In 1969, he joined a small artists co-op to become an art pioneer in the now fashionable SoHo district of New York. As a reorganization president, he converted this co-op on West Broadway into one of the earliest alternative exhibition spaces for emerging artists. In 1970, his first solo exhibition was there, now called Razor Gallery, and consisted of paintings influenced by his investigations at Yale of children’s art development.
From Razor Gallery, Lembeck launched an exhibition career, and included primitive art, graffiti, and subjects related to the harsh physical environment of New York City. He has also done installations, collaborations with other artists as well as solo exhibitions with professional galleries and institutions.
In 1986, Lembeck, looking for fresh inspiration and a change of pace and surroundings, moved with his family to Florida, and from then has commuted between there and New York City.
In Florida, he pursued marine archaeology and geology which involved archaeology-research diving. These interests stem from his childhood when he grew up near the Mississippi mound builder sites. “Brittle Star Park” and “Windscape,” large-scale painting and sculpture installation projects, resulted from these activities.
