Marc Chagall

 “poetic without poetry, mystic without mysticism”. 
Born Moishe Shagal in Belarus, which was then part of the Russian Empire, in 1887. Jews were ostracized within their communities and could not attend "regular" Russian schools and universities. Marc got his early education from Jewish religious school. He was able to attend a Russian high school after his mother bribed the headmaster. There, he saw someone drawing. Not having any art in his own home to have referenced, the process fascinated him. He asked his fellow student how he could draw, and the student told him to find a book in the library to copy the pictures from. He realized he wanted to be a painter. He is arguably one of the most successful artists of the twentieth century. An early modernist who dabbled in the Cubist, Symbolist and Fauvist styles.
 "When Matisse dies," Pablo Picasso remarked in the 1950s, "Chagall will be the only painter left who understands what colour really is"

Shintaro Ohata

Japanese artist that combines 2d and 3d, normally a 3d sculpture in front of a 2d painting.

He has a somewhat painterly style, even with the sculptures. His pieces are glimpses into bits of every day, with an air of melancholy.

He's been exhibiting since 2004.

Jutta Koether

German artist, musician, and critic based in New York.
Was in the 2012 Whitney Biennial.

Vladimir Tatlin

Russian Constructivist. Architect and Artist

Conceived sculptures in order to question the traditional idea of painting.

Designed Tatlin's Tower, a conceptual piece that used industrial materials. It was designed to exemplify modernity, and to hold several geometric shapes that had different functions.The structure consisted of a steel frame in a helix shape that held transportation to the various parts of the tower. The base was a cube that would have lecture space, conference rooms, and meeting spaces.It was designed to make a full rotation in a year.  Above that would have been a pyramid that rotated completely in a month and held executive function.   Next highest would have held a cylinder which was to be a broadcasting center, and rotated over the span of a day. At the very top would have been a hemisphere that held broadcasting equipment.

His paintings are also really interesting, and I like his female nudes the best:

Man Ray

"I paint what cannot be photographed, that which comes from the imagination or from dreams, or from an unconscious drive. I photograph the things that I do not wish to paint, the things which already have an existence." — Undated interview, circa 1970s; published in Man Ray: Photographer, 1981

Born Emmanuel Radnitzky, but refused to acknowledge himself as anything but Man Ray in his lifetime. His family changed their surname to Ray after immigrating to the United States and seeing prevalent anti-Semitism. American modernist, spent most of his career in France.
Was most famous in his day for his portraits and fashion photography, and now he's known for his work within Dada and Surrealist movements.
Helped Duchamp on several pieces, and with Duchamp and Katherine Dreier helped found the first modern museum of art in the United States.

"There is no progress in art, any more than there is progress in making love. There are simply different ways of doing it." — 1948 essay, "To Be Continued, Unnoticed".

Can sex ever be art, or will it always be porn?

At what point does the line blur for sex to be an art form? In India, there are many temples decorated with sexual acts that are considered sacred. In our society it's considered vulgar. The nude is very much an accepted subject matter in our art, and seeing them interacting in romantic ways (think of all the sculptures portraying seductions from Greek myths) is common. But sex itself is taboo to depict.
If sexual acts are engaged in for the sake of an art film, does that make it art or porn? Does sex have to be faked to be artistic? This brings to mind countless movies with mimicry of sex. If it had been real sex, between two consenting adult actors, would that make it pornography? Can they ever be the same thing? Are pornography and tastefulness mutually exclusive?
The supreme court has ruled that porn is the depiction of sexual behavior that is intended to arouse sexual excitement in its audience. Arousal is subjective. In addition, if art is meant to evoke emotions or ideas, how does arousal not have a legitimate conveyance through art?

Postmodern: 
"Of or relating to art, architecture, or literature that reacts against earlier modernist principles, as by reintroducing traditional or classical elements of style or by carrying modernist styles or practices to extremes."
""Postmodern and contemporary artists often adopt, borrow, steal, recycle and/or sample from earlier modern and classical works. They combine or alter these images to create new, contemporary pieces. And many fill their works with a strong sense of self-awareness.” They also work with and combine artistic, scientific, technological, media and digital/Internet tools."
