On April 8, 563 BC, according to Buddhist tradition, Siddhartha Gautama — the Buddha — was born in Lumbini, in present-day Nepal. The Kshatriya prince renounced his life of luxury to seek spiritual enlightenment and, after years of meditation, achieved nirvana under the Bodhi tree in Bodh Gaya, India. His teaching, rejecting the extremes of asceticism and hedonism, became one of the great religions of the world.

On April 8, 1973, Spanish painter Pablo Picasso died in Mougins, France, at age 91. Considered the most influential artist of the twentieth century, co-founder of Cubism alongside Braque and creator of works such as Guernica (1937), Les Demoiselles d'Avignon (1907) and the Portrait of Dora Maar, he left more than 20,000 works in a career spanning 80 years.

On April 8, 1911, the first issue of Der Blaue Reiter (The Blue Rider) was published in Munich — the almanac of the artistic movement of the same name founded by Wassily Kandinsky and Franz Marc, which was one of the pillars of German abstract expressionism. The group, alongside Die Brücke (The Bridge), defined the German artistic avant-gardes of the early twentieth century.
