Henri-Robert-Marcel Duchamp was a French-American painter, sculptor, chess player and writer whose work is associated with Cubism, conceptual art, and Dada, although he was careful about his use of the term Dada and was not directly associated with Dada groups. Duchamp is commonly regarded, along with Pablo Picasso and Henri Matisse, as one of the three artists who helped to define the revolutionary developments in the plastic arts in the opening decades of the twentieth century, responsible for significant developments in painting and sculpture. Duchamp has had an immense impact on twentieth-century and twenty first-century art; and he had a seminal influence on the development of conceptual art. By World War I, he had rejected the work of many of his fellow artists as "retinal" art, intended only to please the eye. Instead, Duchamp wanted to use art to serve the mind.
Anton Pavlovich Chekhov was a Russian playwright and short-story writer, who is considered to be among the greatest writers of short fiction in history. His career as a playwright produced four classics, and his best short stories are held in high esteem by writers and critics. Along with Henrik Ibsen and August Strindberg, Chekhov is often referred to as one of the three seminal figures in the birth of early modernism in the theatre. Chekhov practiced as a medical doctor throughout most of his literary career: "Medicine is my lawful wife", he once said, "and literature is my mistress."
I decided that if I could paint that flower in a huge scale, you could not ignore its beauty.Georgia O'Keeffe
A nation may be born in a day, but the great truths which make for the glory and uplift of the race only through long ages permeate and control humanity. We must have the divine patience and understand the divine mathematics of a thousand years as one day.David Josiah Brewer
