The ophicleide ( /ˈɒfɨklaɪd/) is a family of conical-bore keyed bugles. It has a similar shape to the sudrophone.

The ophicleide was invented in 1817 and patented in 1821 by French instrument maker Jean Hilaire Asté (also known as Halary or Haleri) as an extension to the keyed bugle or Royal Kent bugle family. It was the structural cornerstone of the brass section of the Romantic orchestra, often replacing the serpent, a Renaissance instrument which was thought to be outdated. Its long tubing bends back on itself, and it is played with a cupped mouthpiece similar to modern trombone and euphonium mouthpieces. It originally had nine keys, later expanded to as many as twelve keys, covering the large tone holes. The various members of the ophicleide family may be pitched in B♭and C (bass), or E♭ or F (alto). Contrabass members were known, but rare. The most common members are the bass ophicleides pitched in B♭ or C. Adolph Sax and the modern maker Robb Stewart have also created soprano ophicleides an octave above the bass. Two modern contrabass ophicleides in Eb were built by Mr. Stewart as well.

Anton Hulman "Tony" George (born December 30, 1959) was the former President and CEO of the Indianapolis Motor Speedway and Hulman & Company, serving from 1989 to 2009. He was also formerly on the Board of Directors of both entities. He founded the Indy Racing League and co-owns Vision Racing. Many commentators, such as Gordon Kirby, suggest that George's actions at the head of the Indianapolis Motor Speedway and in creating the IRL to rival the then-dominant CART led to a sharp decline in popularity of open-wheel racing in the United States as it split the fanbase, and gave a significant boost to the national popularity of NASCAR.

Tony George's grandfather, Tony Hulman purchased the Indianapolis Motor Speedway at the end of World War II. George is a former driver, having competed in the 1989 Indy Lights championship, finishing 12th in points and capturing 5 top-tens. His mother (and Hulman's daughter), Mari Hulman George (born 1934), serves as the speedway's Chairman and delivers its famed "ladies and gentlemen, start your engines" public address before every Indianapolis 500.

Hyacinthe Eléonore Klosé (October 11, 1808 in Corfu (Greece) - August 29, 1880 in Paris) was a French clarinet player, professor at the Conservatoire de Paris, and composer.

Klosé is noted for his design improvements to the clarinet using the principles laid down by Theobald Boehm in his innovative work on the flute keywork. From 1839 to 1843, he enlisted the help of Louis-August Buffet of Buffet-Crampon fame, an instrument-making technician, to construct — what is known today as — the Boehm system clarinet^{[citation needed]}.

Klosé was second clarinet at the Théâtre Italien to Frédéric Berr beginning in 1836, then to Iwan Müller following Berr's death in 1838, finally becoming solo clarinet when Müller left in 1841.

In the Paris Conservatory, Klosé had many notable pupils including:

Sir Arthur Seymour Sullivan MVO (13 May 1842 – 22 November 1900) was an English composer of Irish and Italian ancestry. He is best known for his series of 14 operatic collaborations with the dramatist W. S. Gilbert, including such enduring works as H.M.S. Pinafore, The Pirates of Penzance and The Mikado. Sullivan composed 23 operas, 13 major orchestral works, eight choral works and oratorios, two ballets, incidental music to several plays, and numerous hymns and other church pieces, songs, and piano and chamber pieces. The best known of his hymns and songs include "Onward Christian Soldiers" and "The Lost Chord".

The son of a military bandmaster, Sullivan composed his first anthem at age eight. He was selected as soloist in the boys' choir of the Chapel Royal. The Reverend Thomas Helmore, the choirmaster, encouraged Sullivan and arranged for the publication and performance of his early compositions. In 1856, the Royal Academy of Music awarded the first Mendelssohn Scholarship to the 14-year-old Sullivan, allowing him to study first at the Academy and then in Germany, at the Leipzig Conservatoire. His graduation piece was a suite of incidental music to Shakespeare's The Tempest. When it was performed in London in 1862, it was an immediate sensation. Sullivan began his composing career with a series of ambitious works, interspersed with hymns, parlour ballads and other light pieces. Among his best received early pieces were a ballet, L'Île Enchantée (1864), and his Irish Symphony, Cello Concerto and Overture in C (In Memoriam) (all in 1866). From 1861 to 1872, he supplemented his income by working as a church organist and as a music teacher.

Born in Monterey, California in 1955, Yeo holds a bachelor of music degree with honors from Wheaton College in Illinois and a master of arts degree from New York University. His principal teachers were Edward Kleinhammer and Keith Brown.

Before joining the Boston Symphony Orchestra/Boston Pops Orchestra in May 1985, Yeo was a member of the Baltimore Symphony Orchestra, (1981–1985), and was on the faculties of the Peabody Conservatory of Music, in Baltimore, and The Catholic University of America in Washington, D.C.. His background has included a four-year tenure with the Goldman Band, and performances with the Vienna Philharmonic Orchestra, the Mostly Mozart Festival Orchestra, the Gerry Mulligan Big Band, and orchestras for numerous Broadway shows.

In 1998, he was named Music Director of the New England Brass Band, which has released four compact disc recordings under his direction. In 2006, the New England Brass Band, under Mr. Yeo's direction, won first place in the Honors Section at the North American Brass Band Association National Championship, held in Louisville, Kentucky.
