input: The years of World War II were decisive for the history of diving. After the armistice of 1940, the family of Simone and Jacques-Yves Cousteau took refuge in Megeve, where he became a friend of the Ichac family who also lived there. Jacques-Yves Cousteau and Marcel Ichac shared the same desire to reveal to the general public unknown and inaccessible places -- for Cousteau the underwater world and for Ichac the high mountains. The two neighbors took the first ex-aequo prize of the Congress of Documentary Film in 1943, for the first French underwater film: Par dix-huit metres de fond (18 meters deep), made without breathing apparatus the previous year in the Embiez islands (Var) with Philippe Tailliez and Frederic Dumas, using a depth-pressure-proof camera case developed by mechanical engineer Leon Veche (engineer of Arts and Metiers and the Naval College).  In 1943, they made the film Epaves (Shipwrecks), in which they used two of the very first Aqua-Lung prototypes. These prototypes were made in Boulogne-Billancourt by the Air Liquide company, following instructions from Cousteau and Emile Gagnan. When making Epaves, Cousteau could not find the necessary blank reels of movie film, but had to buy hundreds of small still camera film reels the same width, intended for a make of child's camera, and cemented them together to make long reels.  Having kept bonds with the English speakers (he spent part of his childhood in the United States and usually spoke English) and with French soldiers in North Africa (under Admiral Lemonnier), Jacques-Yves Cousteau (whose villa "Baobab" at Sanary (Var) was opposite Admiral Darlan's villa "Reine"), helped the French Navy to join again with the Allies; he assembled a commando operation against the Italian espionage services in France, and received several military decorations for his deeds. At that time, he kept his distance from his brother Pierre-Antoine Cousteau, a "pen anti-semite" who wrote the collaborationist newspaper Je suis partout (I am everywhere) and who received the death sentence in 1946. However, this was later commuted to a life sentence, and Pierre-Antoine was released in 1954.  During the 1940s, Cousteau is credited with improving the aqua-lung design which gave birth to the open-circuit scuba technology used today. According to his first book, The Silent World: A Story of Undersea Discovery and Adventure (1953), Cousteau started diving with Fernez goggles in 1936, and in 1939 used the self-contained underwater breathing apparatus invented in 1926 by Commander Yves le Prieur. Cousteau was not satisfied with the length of time he could spend underwater with the Le Prieur apparatus so he improved it to extend underwater duration by adding a demand regulator, invented in 1942 by Emile Gagnan. In 1943 Cousteau tried out the first prototype aqua-lung which finally made extended underwater exploration possible.

input: O'Keeffe was a legend beginning in the 1920s, known as much for her independent spirit and female role model, as for her dramatic and innovative works of art. Nancy and Jules Heller said, "The most remarkable thing about O'Keefe was the audacity and uniqueness of her early work." At that time, even in Europe, there were few arts exploring abstraction. Even though her works may show elements of different modernist movements, such as Surrealism and Precisionism, her work is uniquely her own style. She received unprecedented acceptance as a woman artist from the fine art world due to her powerful graphic images and within a decade of moving to New York City, she was the highest paid American woman artist. She was known for a distinctive style in all aspects of her life. O'Keeffe was also known for her relationship with Stieglitz, in which she provided some insight in her autobiography.  A substantial part of her estate's assets were transferred to the Georgia O'Keeffe Foundation, a nonprofit. The Georgia O'Keeffe Museum opened in Santa Fe in 1997. The assets included a large body of her work, photographs, archival materials, and her Abiquiu house, library, and property. The Georgia O'Keeffe Home and Studio in Abiquiu was designated a National Historic Landmark in 1998 and is now owned by the Georgia O'Keeffe Museum.  In 1996, the U.S. Postal Service issued a 32 cent stamp honoring O'Keeffe. In 2013, on the 100th anniversary of the Armory Show, the USPS issued a stamp featuring O'Keeffe's Black Mesa Landscape, New Mexico/Out Back of Marie's II, 1930 as part of their Modern Art in America series.  A fossilized species of archosaur was named Effigia okeeffeae ("O'Keeffe's Ghost") in January 2006, "in honor of Georgia O'Keeffe for her numerous paintings of the badlands at Ghost Ranch and her interest in the Coelophysis Quarry when it was discovered".  O'Keeffe holds the record ($44.4 million in 2014) for the highest price paid for a painting by a woman.
