Question: The first performance of the opera "Lord Byron" was choreophraphed by a man that was awarded the Spingarn Medal in what year?
Context: Frederick Douglass Patterson (October 10, 1901 – April 26, 1988), born in Washington D.C. and orphaned at the age of two.  Patterson would later become president of what is now Tuskegee University (1935–1953) and founder of the United Negro College Fund (1944, "UNCF").  In 1987, President Ronald Reagan awarded Dr. Patterson the Presidential Medal of Freedom, the nation’s highest civilian honor.  In 1988, he was awarded the Spingarn Medal from the NAACP. The Spingarn Medal is awarded annually by the National Association for the Advancement of Colored People (NAACP) for outstanding achievement by an African American. The Bad Lord Byron is a 1949 British historical drama film centered on the life of Lord Byron.  It was directed by David MacDonald and starred Dennis Price as Byron with Mai Zetterling, Linden Travers and Joan Greenwood. "Fragment of a Novel" is an unfinished 1819 vampire horror story written by Lord Byron.  The story, also known as "A Fragment" and "The Burial: A Fragment", was one of the first in English to feature a vampire theme.  The main character was Augustus Darvell.  John William Polidori based his novella "The Vampyre" (1819), originally attributed in print to Lord Byron, on the Byron fragment.  The vampire in the Polidori story, Lord Ruthven, was modelled on Byron himself.  The story was the result of the meeting that Byron had in 1816 with Percy Bysshe Shelley where a "ghost writing" contest was proposed.  This contest was also what led to the creation of "Frankenstein" according to Percy Bysshe Shelley's 1818 Preface to the novel.  The story is important in the development and evolution of the vampire story in English literature as one of the first to feature the modern vampire as able to function in society in disguise.  The short story first appeared under the title "A Fragment" in the 1819 collection "Mazeppa: A Poem", published by John Murray in London. Thomas J. "Tom" Bradley (December 29, 1917September 29, 1998) was the 38th Mayor of Los Angeles, serving from 1973 to 1993.  He has been the only African-American mayor of Los Angeles, and his 20 years in office mark the longest tenure by any mayor in the city's history.  His 1973 election made him the second African-American mayor of a major U.S. city.  Bradley retired in 1993, after his approval ratings began dropping subsequent to the 1992 Los Angeles Riots.  Bradley unsuccessfully ran for Governor of California in 1982 and 1986 and was defeated each time by the Republican George Deukmejian.  The racial dynamics that appeared to underlie his narrow and unexpected loss in 1982 gave rise to the political term "the Bradley effect."  In 1985, he was awarded the Spingarn Medal from the NAACP. Lord Byron is an opera in three acts by Virgil Thomson to an original English libretto by Jack Larson, inspired by the historical character Lord Byron.  This was Thomson's third and final opera.  He wrote it on commission from the Ford Foundation for the Metropolitan Opera (Met), but the Met never produced the opera.  The first performance was at Lincoln Center, New York City on April 20, 1972, by the music department of the Juilliard School with John Houseman as stage director, Gerhard Samuel as the conductor and Alvin Ailey as the choreographer.  A performance of a revised version, by the composer, took place in 1985 with the New York Opera Repertory Theater. Alvin Ailey (January 5, 1931 – December 1, 1989) was an African-American choreographer and activist who founded the Alvin Ailey American Dance Theater in New York City.  He is credited with popularizing modern dance and revolutionizing African-American participation in 20th-century concert dance.  His company gained the nickname "Cultural Ambassador to the World" because of its extensive international touring.  Ailey's choreographic masterpiece "Revelations" is believed to be the best known and most often seen modern dance performance.  In 1977, Ailey was awarded the Spingarn Medal from the NAACP.  He received the Kennedy Center Honors in 1988.  In 2014, President Barack Obama selected Ailey to be a posthumous recipient of the Presidential Medal of Freedom. Henry Alexander Hunt (October 10, 1866 – October 1, 1938) was an African-American educator who led efforts to reach blacks in rural areas of Georgia.  He was awarded the Spingarn Medal by the National Association for the Advancement of Colored People (NAACP), as well as the Harmon Prize.  In addition, he was recruited in the 1930s by President Franklin D. Roosevelt to join the president's Black Cabinet, an informal group of more than 40 prominent African Americans appointed to positions in the executive agencies. Joel Elias Spingarn High School was a public high school located in the District of Columbia.

Glenarvon is Lady Caroline Lamb's first novel, published in 1816.  Its rakish title character, Lord Ruthven, is an unflattering depiction of her ex-lover, Lord Byron.  Drawing from "Glenarvon", John Polidori used a vampire named Lord Ruthven as a characterization of Lord Byron in his short story "The Vampyre" published in 1819.
