The horn, commonly known as the French horn, is a brass instrument made of about 12–13 feet (3.7–4.0 m) of tubing wrapped into a coil with a flared bell. A musician who plays the horn is called a horn player (or less frequently, a hornist). In informal use, "horn" can refer to nearly any wind instrument with a flared exit for the sound.

Descended from the natural horn, the instrument is often informally known as the French horn (perhaps to make the sharp distinction with English horn, a woodwind descendant of the oboe da caccia). But the instrument is German in origin, not French, and for this reason the International Horn Society has since 1971 recommended that it be called simply horn. Despite this guidance, French horn remains the most common name for the instrument in the United States.

Horns have valves, operated with the left hand, to route the air into extra tubing to change the pitch. Most horns have lever-operated rotary valves, but some horns like the Vienna horn use piston valves (similar to trumpet valves). A horn without valves is known as a natural horn, changing pitch along the natural harmonics of the instrument (similar to a bugle), but with a wide range of notes due to the long tubing, coupled with a small mouthpiece, which makes the playable range of the horn higher in the harmonic series, where pitches are closer together.

John Towner Williams (born February 8, 1932) is an American composer, conductor, and pianist. In a career spanning almost six decades, he has composed some of the most recognizable film scores in the history of motion pictures, including the Star Wars saga, Jaws, Superman, the Indiana Jones films, E.T. the Extra-Terrestrial, Hook, Jurassic Park, Schindler's List, War Horse, Home Alone and the first three Harry Potter films. He has had a long association with director Steven Spielberg, composing the music for all but two (Duel and The Color Purple) of Spielberg's major feature films.

Other notable works by Williams include theme music for four Olympic Games, NBC Sunday Night Football, the NBC Nightly News, the rededication of the Statue of Liberty, and the television series Lost in Space. Williams has also composed numerous classical concerti, and he served as the principal conductor of the Boston Pops Orchestra from 1980 to 1993; he is now the orchestra's conductor laureate.

Williams has won five Academy Awards, four Golden Globe Awards, seven BAFTA Awards, and 21 Grammy Awards. With 47 Academy Award nominations, Williams is the second most nominated person, after Walt Disney. John Williams was honored with the prestigious Richard Kirk award at the 1999 BMI Film and TV Awards. The award is given annually to a composer who has made significant contributions to film and television music. Williams was inducted into the Hollywood Bowl Hall of Fame in 2000, and was a recipient of the Kennedy Center Honors in 2004.

Siegfried Herbert Horn (March 17, 1908 – November 28, 1993) was a Seventh-day Adventist archaeologist and Bible scholar. He is perhaps best known for his numerous books and articles and for his excavations at Tell Hesban in Jordan. He was Professor of History of Antiquity at the Seventh-day Adventist Theological Seminary in Berrien Springs, Michigan (now part of Andrews University). The Siegfried H. Horn Museum at Andrews University was named in his honor. A scholar of wide-ranging interests and abilities, he made significant contributions especially in the areas of Ancient Near Eastern chronology and archaeology. In a 1985 questionnaire of North American Adventist lecturers, Horn tied for seventh place among the Adventist authors who had most influenced them.

Horn was born March 17, 1908, to Albin and Klara Horn in Wurzen, Saxony, Germany. His father was one of the world's earliest aviators, trained as a pilot by Louis Blériot. Horn served as a minister and as a missionary from 1930 to 1940, first in the Netherlands and then in the Dutch East Indies. Because he was German, Horn spent six and a half years as a prisoner of war during World War II, from 1940 to 1946, first as a prisoner of the Dutch in Indonesia and then imprisoned by the English in India. Granted access to books, Horn made use of this time to develop his skills in Greek and Hebrew and to teach his fellow inmates. Upon gaining his freedom at the end of World War II, Horn immigrated to the United States and completed his education. He earned a B.A. at Walla Walla College (now a University) in Washington State (1947), an M.A. at the Seventh-day Adventist Theological Seminary in Washington, D.C. (1948), and a Ph.D. in Egyptology at the Oriental Institute of the University of Chicago (1951). He studied briefly under William F. Albright at Johns Hopkins University.
