Some context: Pieter Cornelis "Piet" Mondriaan, after 1906 Mondrian (; Dutch: ['pit 'mondrija:n], later ['mondrijan]; 7 March 1872 - 1 February 1944), was a Dutch painter and theoretician who is regarded as one of the greatest artists of the 20th century. He is known for being one of the pioneers of 20th century abstract art, as he changed his artistic direction from figurative painting to an increasingly abstract style, until he reached a point where his artistic vocabulary was reduced to simple geometric elements. Mondrian's art was highly utopian and was concerned with a search for universal values and aesthetics. He proclaimed in 1914: Art is higher than reality and has no direct relation to reality.
When the 47-year-old Piet Mondrian left the Netherlands for unfettered Paris for the second and last time in 1919, he set about at once to make his studio a nurturing environment for paintings he had in mind that would increasingly express the principles of neoplasticism about which he had been writing for two years. To hide the studio's structural flaws quickly and inexpensively, he tacked up large rectangular placards, each in a single color or neutral hue. Smaller colored paper squares and rectangles, composed together, accented the walls. Then came an intense period of painting. Again he addressed the walls, repositioning the colored cutouts, adding to their number, altering the dynamics of color and space, producing new tensions and equilibrium. Before long, he had established a creative schedule in which a period of painting took turns with a period of experimentally regrouping the smaller papers on the walls, a process that directly fed the next period of painting. It was a pattern he followed for the rest of his life, through wartime moves from Paris to London's Hampstead in 1938 and 1940, across the Atlantic to Manhattan.  At the age of 71 in the fall of 1943, Mondrian moved into his second and final Manhattan studio at 15 East 59th Street, and set about to recreate the environment he had learned over the years was most congenial to his modest way of life and most stimulating to his art. He painted the high walls the same off-white he used on his easel and on the seats, tables and storage cases he designed and fashioned meticulously from discarded orange and apple-crates. He glossed the top of a white metal stool in the same brilliant primary red he applied to the cardboard sheath he made for the radio-phonograph that spilled forth his beloved jazz from well-traveled records. Visitors to this last studio seldom saw more than one or two new canvases, but found, often to their astonishment, that eight large compositions of colored bits of paper he had tacked and re-tacked to the walls in ever-changing relationships constituted together an environment that, paradoxically and simultaneously, was both kinetic and serene, stimulating and restful. It was the best space, Mondrian said, that he had inhabited. He was there for only a few months, as he died in February 1944.  After his death, Mondrian's friend and sponsor in Manhattan, artist Harry Holtzman, and another painter friend, Fritz Glarner, carefully documented the studio on film and in still photographs before opening it to the public for a six-week exhibition. Before dismantling the studio, Holtzman (who was also Mondrian's heir) traced the wall compositions precisely, prepared exact portable facsimiles of the space each had occupied, and affixed to each the original surviving cut-out components. These portable Mondrian compositions have become known as "The Wall Works". Since Mondrian's death, they have been exhibited twice at Manhattan's Museum of Modern Art (1983 and 1995-96), once in SoHo at the Carpenter + Hochman Gallery (1984), once each at the Galerie Tokoro in Tokyo, Japan (1993), the XXII Biennial of Sao Paulo (1994), the University of Michigan (1995), and - the first time shown in Europe - at the Akademie der Kunste (Academy of The Arts), in Berlin (22 February - 22 April 2007).

Some context: Weldon Gaston "Hum" Humble (April 24, 1921 - April 14, 1998) was an American football guard who played five seasons in the All-America Football Conference (AAFC) and National Football League (NFL) for the Cleveland Browns and Dallas Texans in the late 1940s and early 1950s. Humble grew up in Texas and was a multi-sport athlete at Brackenridge High School in San Antonio. He enrolled at Rice University in Houston, Texas in 1940 and played three seasons on the school's football team. Humble then spent three years in the U.S. Marines during World War II, serving in the Pacific War and earning a Bronze Star Medal before returning to complete his college studies in 1946.
Humble was born in Nixon, Texas, a suburb of San Antonio, in 1921. His athletic career began at San Antonio's Brackenridge High School. Humble played as an end for two seasons and a fullback for a third season on the football team. He also played on the basketball, track and swimming teams before graduating and enrolling at Rice University in Houston, Texas in 1940.  Humble began play on Rice's freshman team as an end in 1940. He advanced to the varsity team the next year. While he started as an end, coach Jess Neely switched him to guard before the first game of the season. He thrived in the new position, and was named a sophomore all-star by the Associated Press after the Rice Owls finished 1941 with a 6-3-1 win-loss-tie record. The following year, Humble earned All-Southwestern Conference honors and won the George Martin Award, given to Rice's most valuable player, as Rice put up a 7-2-1 record.  Humble left Rice in 1943 for the University of Louisiana at Lafayette, then called Southwestern Louisiana Institute, to prepare for service in World War II in a V-12 U.S. Navy training program. As he trained, he played alongside enlistees from Tulane University, the University of Tulsa and Louisiana State University on a military team that won six straight games and was selected to play in the first Oil Bowl in Houston. Captained by Humble, Southwestern beat a service team from Randolph Air Force Base in San Antonio.  After the season, Humble enlisted in the United States Marine Corps and was sent to fight in the Pacific War. He rose to the rank of first lieutenant and won a Bronze Star Medal. Upon his discharge in 1946, Humble returned to Rice. He lettered in football and track and field and was voted a consensus first-team All-American guard while captain of Rice's Southwestern Conference co-champion team. He was also named lineman of the week by the Associated Press in November for his strong tackling in a game against the Texas A&M Aggies. After finishing with an 8-2 record, Rice beat Tennessee in the Orange Bowl game in early 1947. Rice was ranked the 10th-best college team in the nation in the AP Poll.
