Sinclair Lewis awarded the Nobel Prize in Literature "for his vigorous and graphic art of description and his ability to create, with wit and humour, new types of characters".

Photograph by Man Ray: Yeshwant Rao Holkar II and Sanyogita Devi of Indore. The Maharaja of Indore spent much time in Europe and the United States (one of his homes was in Santa Ana, California). He became a patron of many important artists and designers of his day. The Paris-based American avant-garde photographer Man Ray photographed Yeshwant Rao Holkar extensively. This informal and intimate image of the Maharaja and his wife were probably taken when they were on holiday in Cannes, in the south of France.

Painting by Grant Wood: American Gothic. Wood's inspiration came from what is now known as the American Gothic House, and his decision to paint the house along with "the kind of people I fancied should live in that house." Created in 1930, it depicts a farmer standing beside a woman that has been interpreted to be either his wife or his daughter. The figures were modeled by Wood's sister, Nan Wood Graham, and a local dentist, Dr. Byron McKeeby. The woman is dressed in a colonial print apron evoking 19th-century Americana, and the man is holding a pitchfork. It is one of the most familiar images in 20th-century American art, and has been widely parodied in American popular culture.

Painting by Salvador Dalí: The Persistence of Memory (Catalan: La persistència de la memòria) is one of his most recognizable works. First shown at the Julien Levy Gallery in 1932, since 1934 the painting has been in the collection of the Museum of Modern Art (MoMA) in New York City, which received it from an anonymous donor. The well-known surrealist piece introduced the image of the soft melting pocket watch. It epitomizes Dalí's theory of "softness" and "hardness", which was central to his thinking at the time. As Dawn Adès wrote, "The soft watches are an unconscious symbol of the relativity of space and time, a Surrealist meditation on the collapse of our notions of a fixed cosmic order". This interpretation suggests that Dalí was incorporating an understanding of the world introduced by Albert Einstein's theory of special relativity. Asked by Ilya Prigogine whether this was in fact the case, Dalí replied that the soft watches were not inspired by the theory of relativity, but by the surrealist perception of a Camembert melting in the sun.

Cimarron wins Academy Award for best picture. This big-scale Hollywood western was based on the novel by Edna Ferber. The land-rush scene is still effective, but the acting is sometimes a reminder that some actors had a hard time making the transition from big theatrical acting to subtler film work.

Painting by Pablo Picasso: Le Rêve (French, "The Dream") portrays his 22-year-old mistress Marie-Thérèse Walter. It is said to have been painted in one afternoon, on 24 January 1932. It belongs to Picasso's period of distorted depictions, with its oversimplified outlines and contrasted colors resembling early Fauvism. In 2001, casino magnate Steve Wynn purchased the work for an undisclosed sum, estimated to be about $60 million. In October 2006, Wynn told a group of his friends that he had agreed the day before to sell the painting for $139 million to Steven A. Cohen. At the time, this price would have made Le Rêve the most expensive piece of art ever. While Wynn was showing the painting to his friends, he put his right elbow through the canvas, puncturing the left forearm of the figure and creating a six-inch tear. After a $90,000 repair, the painting was re-valued at $85 million. Wynn filed a claim to recover the $54 million perceived loss from his Lloyd's of London insurers, an amount which would have covered most of the initial cost of buying the painting. When the insurers balked, Wynn sued them in January 2007. The case was eventually settled out of court in March 2007. Cohen bought the painting from Wynn in 2013 for $155 million. The price is estimated to be the highest ever paid, up to that time, for an artwork by a U.S. collector

Luigi Pirandello awarded the Nobel Prize in Literature "for his bold and ingenious revival of dramatic and scenic art".

Currency as Art: The United States one-hundred-thousand-dollar bill (US$100,000), created during the Great Depression in response to the hoarding of gold. The bill, which features President Woodrow Wilson, was created as a large denomination note for gold transactions between Federal Reserve Banks; it never circulated publicly and its private possession is illegal. About 42,000 of the $100,000 bills were printed. Many were destroyed in the years following their commission, with the remaining few in possession of the United States federal government. The $100,000 bill, in possession aside from the federal government, is deemed illegal on account of its large denomination and the regulations declared at its signing.

Fresco by Diego Rivera: Man at the Crossroads was intended for New York City's Rockefeller Center. The painting was controversial because it included an image of Lenin and a Soviet Russian May Day parade. Despite protests from artists, Nelson Rockefeller ordered its destruction before it was completed. Only black-and-white photographs exist of the original incomplete mural, taken when Rivera was forced to stop work on it. Using the photographs, Rivera repainted the composition in Mexico under the variant title Man, Controller of the Universe. The creation and destruction of the mural is dramatized in the films Cradle Will Rock (1999) and Frida (2002).

Architecture by Frank Lloyd Wright: Fallingwater or the Kaufmann Residence is a house in rural southwestern Pennsylvania, 43 miles southeast of Pittsburgh. The home was built partly over a waterfall on Bear Run in the Mill Run section of Stewart Township, Fayette County, Pennsylvania, in the Laurel Highlands of the Allegheny Mountains. The house was designed as a weekend home for the family of Liliane Kaufmann and her husband, Edgar J. Kaufmann, owner of Kaufmann's department store. Time cited it after its completion as Wright's "most beautiful job"; it is listed among Smithsonian's Life List of 28 places "to visit before you die". It was designated a National Historic Landmark in 1966. In 1991, members of the American Institute of Architects named the house the "best all-time work of American architecture" and in 2007, it was ranked 29th on the list of America's Favorite Architecture according to the AIA.

Mutiny on the Bounty wins Academy Award for best picture. The MGM spectacle is the third (and so far, last) film to take top prize with no other wins, after Broadway Melody and Grand Hotel. It is also the only film to have three best actor nominations: Clark Gable, Charles Laughton and Franchot Tone. The overcrowding helped lead to the Academy's creation of the supporting actor and actress categories.

Eugene Gladstone O'Neill awarded the Nobel Prize in Literature "for the power, honesty and deep-felt emotions of his dramatic works, which embody an original concept of tragedy".

Photograph by Dorothea Lange: Migrant Mother is one of a series of photographs that Lange made of Florence Owens Thompson and her children in February or March of 1936 in Nipomo, California. Lange was concluding a month's trip photographing migratory farm labor around the state for what was then the Resettlement Administration. The images were made using a Graflex camera. The original negatives are 4x5" film. In 1960, Lange gave this account of the experience: I saw and approached the hungry and desperate mother, as if drawn by a magnet. I do not remember how I explained my presence or my camera to her, but I do remember she asked me no questions. I made five exposures, working closer and closer from the same direction. I did not ask her name or her history. She told me her age, that she was thirty-two. She said that they had been living on frozen vegetables from the surrounding fields, and birds that the children killed. She had just sold the tires from her car to buy food. There she sat in that lean- to tent with her children huddled around her, and seemed to know that my pictures might help her, and so she helped me. There was a sort of equality about it.

Sculpture by Méret Oppenheim: Object (Le Déjeuner en fourrure) [Object (Breakfast in Fur)]. The sculpture consists of a teacup, saucer and spoon that the artist covered with fur from a Chinese gazelle. The fur suggests an expensively decked-out woman; the cup, hollow yet round, can evoke female genitalia; the spoon with its phallic shape further eroticizes the hairy object. It was purchased by Alfred Barr for the collection of the Museum of Modern Art in New York and included the museum's first surrealist exhibition Fantastic Art: Dada and Surrealism in 1936. Oppenheim was willing to sell the piece for one thousand francs, but Barr only offered her $50 and she accepted. This was the first piece of art that the museum acquired, and Oppenheim became known as the First Lady of MoMA. The enormous success of this early work would later create problems for Oppenheim as an artist. Soon after its creation she drifted away from the Surrealists. Decades later, in 1972, she artistically commented on its dominance of her career by producing a number of "souvenirs" of Le Déjeuner en fourrure.

Painting by Pablo Picasso: Guernica is a mural-sized work that Picasso completed in June 1937, at his home on Rue des Grands Augustins, in Paris. The painting, which uses a palette of gray, black, and white, is regarded by many art critics as one of the most moving and powerful anti-war paintings in history. Standing at 3.49 meters (11 ft 5 in) tall and 7.76 meters (25 ft 6 in) wide, the large mural shows the suffering of people wrenched by violence and chaos. Prominent in the composition are a gored horse, a bull, and flames. The painting was created in response to the bombing of Guernica, a Basque Country village in northern Spain, by Nazi German and Fascist Italian warplanes at the request of the Spanish Nationalists. Upon completion, Guernica was exhibited at the Spanish display at the Exposition Internationale des Arts et Techniques dans la Vie Moderne (Paris International Exposition) in the 1937 World's Fair in Paris and then at other venues around the world. The touring exhibition was used to raise funds for Spanish war relief. The painting became famous and widely acclaimed, and it helped bring worldwide attention to the Spanish Civil War.

Painting by Pablo Picasso: The Weeping Woman. Picasso was intrigued with the subject, and revisited the theme numerous times that year. This painting was the final and most elaborate of the series. It has been in the collection of the Tate in London since 1987, and is on exhibition at the Tate Modern, London. Dora Maar was Picasso's mistress from 1936 until 1944. In the course of their relationship, Picasso painted her in a number of guises, some realistic, some benign, others tortured or threatening. Picasso explained: For me she's the weeping woman. For years I've painted her in tortured forms, not through sadism, and not with pleasure, either; just obeying a vision that forced itself on me. It was the deep reality, not the superficial one.

The Life of Emile Zola wins Academy Award for best picture. The bio of French novelist Zola is mostly centered on his passionate defense of Capt. Alfred Dreyfus, who was falsely accused of treason and sentenced to Devil's Island. It's a good old-fashioned Hollywood biopic, with plenty of fictional touches, that is a great showcase for Paul Muni in the title role.

Pearl Buck awarded the Nobel Prize in Literature "for her rich and truly epic descriptions of peasant life in China and for her biographical masterpieces".

Painting by René Magritte: Time Transfixed (La Durée poignardée) is part of the permanent collection of the Art Institute of Chicago and is usually on display in the museum's new Modern Wing. The painting was one of many done for surrealist patron and Magritte supporter Edward James. The painting depicts a locomotive jutting out of a fireplace, at full steam, in an empty room. Above the mantelpiece is a tall mirror. Only the clock and one candlestick standing on the mantelpiece are reflected in the mirror. The title of the painting translates to English literally as "Ongoing Time Stabbed by a Dagger" and Magritte was reportedly unhappy with the generally accepted translation of "Time Transfixed".

Fishermen find a coelacanth, a fish long believed to be extinct, off the coast of South Africa. Margaret Courtney-Latimer, a curator at the East London Museum in South Africa, keeps the fish preserved long enough for its identity to be confirmed by ichthyologist J.L.B. Smith.

You Can't Take It with You wins Academy Award for best picture. This was the second Frank Capra film to take the top prize. The film is a sweet, zany comedy, but many pundits think that a major factor in its win was Capra's crucial role in keeping the peace between studios and the new guilds; some had predicted a long strike. Others predicted the end of Hollywood.

August 23, the Molotov–Ribbentrop Pact, officially the Treaty of Non-Aggression between Germany and the Union of Soviet Socialist Republics, and also known as the Hitler–Stalin Pact and the Nazi–Soviet Pact, was a non-aggression pact between Nazi Germany and the Soviet Union, with a secret protocol establishing Soviet and German spheres of influence across Northern Europe. The pact was signed in Moscow by Soviet Foreign Minister Vyacheslav Molotov and German Foreign Minister Joachim von Ribbentrop. One week after signing the pact, on 1 September 1939, Germany invaded Poland.

About 200 worked ivory fragments, roughly 32,000 years old, are found in the Hohlenstein-Stadel Cave in Germany. Three decades later, the pieces will be reassembled as statue of a lion-headed man.

Gone with the Wind wins Academy Award for best picture. Producer David O. Selznick optioned Margaret Mitchell's novel before it became a huge best-seller, and his search for an actress to play Scarlett O Hara was a pinnacle of Hollywood publicity. Anticipation was ridiculously high when the film opened, but fans embraced the movie and star Vivien Leigh, who won an Oscar (one of eight that the film earned). It also happened to be the only color film to take the Best Picture prize in the Academy's first 23 years.
