Baron is a title of nobility. In the kingdom of England, the medieval Latin word baro, baronis, was used originally to denote a tenant-in-chief of the early Norman kings, who held his lands by the feudal tenure of "barony", in Latin per baroniam, and who was entitled to attend the Great Council which by the 13th century had developed into the Parliament of England.

The title was quite common in most European countries often in a slightly modified form. In Italian, the word used was Barone. The corresponding title in the Holy Roman Empire was Freiherr.

The word baron comes from the Old French baron, from a Late Latin baro "man; servant, soldier, mercenary" (so used in Salic Law; Alemannic Law has barus in the same sense). Isidore in the 7th century thought the word was from Greek βαρύς "heavy" (because of the "heavy work" done by mercenaries), but the word is presumably of Old Frankish origin, cognate with Old English beorn meaning "warrior, nobleman"). Cornutus in the first century already reports a word barones which he took to be of Gaulish origin. He glosses it as meaning servos militum and explains it as meaning "stupid", by reference to classical Latin bāro "simpleton, dunce"; because of this early reference, the word has also been suggested to derive from an otherwise unknown Celtic *bar, but OED takes this to be "a figment".

Baron Walter Louis Davis (born April 13, 1979) is an American professional basketball player who currently plays for the New York Knicks of the National Basketball Association (NBA). A two-time NBA All-Star, he was drafted as the third pick in the 1999 NBA Draft by the Charlotte Hornets. He went on to play for the Golden State Warriors, Los Angeles Clippers and Cleveland Cavaliers before signing with New York as a free agent in 2011. Davis played college basketball at the UCLA, where he was an All-America honoree before turning professional after his sophomore year. He was a star high school player while at Crossroads School.

Davis was born in Los Angeles. His grandmother and guardian, Lela Nicholson, was instrumental in pushing him to play basketball. With her encouragement, he eventually enrolled at Crossroads School, a prestigious private school in Santa Monica, California.

As a senior at Crossroads, Davis led his team to the Championship of The Beach Ball Classic tournament in Myrtle Beach, South Carolina over perennial prep powerhouse Christ The King Regional High School (Queens, New York), while earning MVP honors and a spot on the All-Tournament team along with future St. John's standout Erick Barkley at that prestigious event. That year, Davis was also named Gatorade National Player of the Year and a Parade All-American. He was also selected to play in the prestigious McDonald's All-American High School Basketball Game in Colorado Springs in 1997, playing with future NBA players Elton Brand, Shane Battier, Larry Hughes and Ron Artest, and winning the Sprite Slam Dunk Contest despite being the smallest man in the competition at 6'2."

A graduate of Cambridge University, Baron Cohen is most widely known for writing and playing four unorthodox fictional characters: Ali G, Borat, Brüno, and Admiral General Aladeen.

Baron Cohen was named Best Newcomer at the 1999 British Comedy Awards for The 11 O'Clock Show, and since then, his work has been further recognised with two BAFTA Awards for Da Ali G Show, several Emmy nominations, a nomination for an Academy Award for Writing Adapted Screenplay, and a Golden Globe for Best Actor for his work in the feature film Borat: Cultural Learnings of America for Make Benefit Glorious Nation of Kazakhstan. After the release of Borat, Baron Cohen stated that because the public had become too familiar with the characters, he would retire Borat and Ali G. Similarly, after the release of Brüno, Baron Cohen has stated he would also retire the title character.

In 1996, David Letterman was ranked #45 on TV Guide's 50 Greatest TV Stars of All Time.

Letterman was born in Indianapolis, Indiana. His father, Harry Joseph Letterman (April 1915 – February 1973), was a florist of British descent; his mother Dorothy Letterman (née Hofert, now Dorothy Mengering), a Presbyterian church secretary of German descent, is an occasional figure on the show, usually at holidays and birthdays.

Édouard Louis Joseph, Baron Empain (20 September 1852 - 22 July 1929) was a wealthy Belgian engineer, entrepreneur, financier and industrialist, as well as an amateur Egyptologist.

Empain was born at Belœil, Belgium, and was the son of schoolteacher François Julien Empain and his wife Catherine (née Solivier). He went into business with his brother, Baron François Empain and other family members, and amassed a great fortune.

Empain began his career a draughtsman at a metallurgical company, Société métallurgique, in 1878, and became involved in railway construction when he noticed that transport infrastructure in the countryside was inadequate. After success in Belgium with the Liege-Jemeppe line, his companies developed several railway lines in France, including the creation of the Paris Métro.

Because he felt that he depended too much on the banks for his industrial plans, in 1881 he founded his own bank, Banque Empain, which later became the Belgian Industrial Bank ("Banque Industrielle Belge"). The Empain group of companies expanded greatly throughout the 1890s, constructing electric urban tramlines in Europe, Russia, China, the Belgian Congo, and in Cairo, Egypt. Desiring to also be independent of electricity producers, Empain also was involved in forming a number of electricity companies to power his projects.
