Some context: (Franz) Joseph Haydn (; German: ['jo:zef 'haId@n] ( listen); 31 March 1732 - 31 May 1809) was an Austrian composer of the Classical period. He was instrumental in the development of chamber music such as the piano trio and his contributions to musical form have earned him the epithets "Father of the Symphony" and "Father of the String Quartet".
Haydn returned to Vienna in 1795. Prince Anton had died, and his successor Nikolaus II proposed that the Esterhazy musical establishment be revived with Haydn serving again as Kapellmeister. Haydn took up the position on a part-time basis. He spent his summers with the Esterhazys in Eisenstadt, and over the course of several years wrote six masses for them.  By this time Haydn had become a public figure in Vienna. He spent most of his time in his home, a large house in the suburb of Windmuhle, and wrote works for public performance. In collaboration with his librettist and mentor Gottfried van Swieten, and with funding from van Swieten's Gesellschaft der Associierten, he composed his two great oratorios, The Creation (1798) and The Seasons (1801). Both were enthusiastically received. Haydn frequently appeared before the public, often leading performances of The Creation and The Seasons for charity benefits, including Tonkunstler-Societat programs with massed musical forces. He also composed instrumental music: the popular Trumpet Concerto, and the last nine in his long series of string quartets, including the Fifths, Emperor, and Sunrise. A brief work, "Gott erhalte Franz den Kaiser" (the "Emperor's Hymn"; 1797), achieved great success and became "the enduring emblem of Austrian identity right up to the First World War" (Jones); in modern times it became (with different words) the national anthem of Germany.  During the later years of this successful period, Haydn faced incipient old age and fluctuating health, and he had to struggle to complete his final works. His last major work, from 1802, was the sixth mass for the Esterhazys, the Harmoniemesse.

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.
Paul Brown, the coach of the Cleveland Browns in the All-America Football Conference (AAFC), met Humble while vacationing in Florida in 1946. Brown came to watch the Orange Bowl on New Year's Day, and was staying in the same hotel as the Rice team. He saw Humble and his wife Lorraine, whom Humble had met while in training at Southwestern, on a dance floor at the hotel. "He appeared to be the sort of fellow we like to have on our team," Brown said later in 1947. "Then I watched him in that Tennessee game and after that made up my mind he'd be with my club if I ever had the chance to make a deal for him." The AAFC's Baltimore Colts selected Humble in the league's draft, but Brown got his chance in August. He engineered a trade that sent four players including quarterback Steve Nemeth and guard George Cheroke to the Colts, plus two players to be named later.  Before joining the Browns, Humble played in the College All-Star Game, a now-defunct annual matchup between the National Football League (NFL) champion and a selection of the best college players from around the country. The college all-stars won the game, defeating the Chicago Bears 16-0. In Cleveland, Humble was part of an offensive line that included Lin Houston, Ed Ulinski and Bob Gaudio. Their job was to protect quarterback Otto Graham from opposing defenders and open up running room for fullback Marion Motley. They chanted "nobody touches Graham" when they broke the huddle.  Helped by strong line play, Graham, Motley and Cleveland ends Dante Lavelli and Mac Speedie led a potent offense that dominated the AAFC for three years. The Browns won the AAFC championship in 1947, 1948 and 1949 before the league disbanded and Cleveland was absorbed by the more established NFL. Humble was a consensus second-team All-Pro selection in 1948, when Cleveland won all of its games. Cleveland's success continued in the NFL in 1950, when Humble was used on occasion as a linebacker on defense. The Browns finished the season with a 10-2 record and beat the Los Angeles Rams in the NFL championship game. Humble was selected to play in the first-ever Pro Bowl, the NFL's all-star game.  Humble continued as a member of the Marine Reserves as his professional career continued, and in 1951 he was in danger of being called up for service in the Korean War. He re-enlisted in the summer and played for a military team at Marine Corps Base Quantico later in the year. After the season, he was named the best service player in the country by the Washington Touchdown Club.  Humble was expected to return to the Browns after his discharge from the military in 1952. In a surprise move, however, Brown traded him before the season to the Dallas Texans for fullback Sherman Howard. The trade was unexpected because Cleveland's other guards, including Gaudio and Alex Agase, were getting older and nearing retirement. "I'm sure we'll be all right at the guard position," Brown said at the time. "But we do have a definite fullback problem." Humble played one season for the Texans before retiring. Dallas had a 1-11 record in 1952.
