The United States Steel Corporation (NYSE: X), more commonly known as U.S. Steel, is an integrated steel producer with major production operations in the United States, Canada, and Central Europe. The company is the world's tenth largest steel producer. It was renamed USX Corporation in 1991 and back to United States Steel Corporation in 2001 when the shareholders of USX spun off its steel-making assets following the acquisition of Marathon Oil and Texas Gas in 1982. It is still the largest domestically owned integrated steel producer in the United States, although it produces only slightly more steel than it did in 1902.

U.S. Steel is a former Dow Jones Industrial Average component, listed from April 1, 1901 to May 3, 1991. It was removed under its USX Corporation name with Navistar International and Primerica Corporation.^{[dead link]}

J. P. Morgan and the attorney Elbert H. Gary founded U.S. Steel in 1901 (incorporated on February 25) by combining Andrew Carnegie's Carnegie Steel Company with Gary's Federal Steel Company and William Henry "Judge" Moore's National Steel Company for $492 million ($13.74 billion today). It was capitalized at $1.4 billion ($39.11 billion today), making it the world's first billion-dollar corporation. At one time, U.S. Steel was the largest steel producer and largest corporation in the world. In 1907 it bought its largest competitor Tennessee Coal, Iron and Railroad Company which was headquartered in Birmingham, Alabama. This led to Tennessee Coal's being replaced in the Dow Jones Industrial Average by the General Electric Company. The federal government attempted to use federal antitrust laws to break up U.S. Steel in 1911, but that effort ultimately failed. Time and competitors have, however, accomplished nearly the same thing. In its first full year of operation, U.S. Steel made 67 percent of all the steel produced in the United States. It now produces less than 10 percent.

The United States of America (commonly abbreviated to the United States, the U.S., the USA, America, and the States) is a federal constitutional republic comprising fifty states and a federal district. The country is situated mostly in central North America, where its forty-eight contiguous states and Washington, D.C., the capital district, lie between the Pacific and Atlantic Oceans, bordered by Canada to the north and Mexico to the south. The state of Alaska is in the northwest of the continent, with Canada to the east and Russia to the west, across the Bering Strait. The state of Hawaii is an archipelago in the mid-Pacific. The country also possesses several territories in the Pacific and Caribbean.

At 3.79 million square miles (9.83 million km²) and with over 312 million people, the United States is the third or fourth largest country by total area, and the third largest by both land area and population. It is one of the world's most ethnically diverse and multicultural nations, the product of large-scale immigration from many countries. The U.S. economy is the world's largest national economy, with an estimated 2011 GDP of $15.1 trillion (22% of nominal global GDP and over 19% of global GDP at purchasing-power parity). Per capita income is the world's sixth-highest.

Walter Brennan (July 25, 1894 – September 21, 1974) was an American actor. Brennan won the Academy Award for Best Supporting Actor on three separate occasions, which is currently the record for most Oscar wins by a male actor, tied with Jack Nicholson.

Born in Lynn, Massachusetts, less than two miles from his family's home in Swampscott, Walter Andrew Brennan was the second of three children born to Irish immigrants William John Brennan and Margaret Elizabeth Flanagan. The elder Brennan was an engineer and inventor, and young Walter studied engineering at Rindge Technical High School in Cambridge, Massachusetts.

While in school, Brennan became interested in acting, and began to perform in vaudeville. While working as a bank clerk, he enlisted in the U.S. Army and served as a private with the 101st Field Artillery Regiment in France during World War I. Following the war, he moved to Guatemala and raised pineapples, before settling in Los Angeles. During the 1920s, he became involved in the real estate market, where he made a fortune. Unfortunately, he lost most of his money when the market took a sudden downturn due to the Great Depression.^{[citation needed]}

Lowell Jackson Thomas (April 6, 1892 – August 29, 1981) was an American writer, broadcaster, and traveler, best known as the man who made Lawrence of Arabia famous. So varied were Thomas's activities that when it came time for the Library of Congress to catalog his memoirs they were forced to put them in "CT" ("biographies of subjects who do not fit into any other category") in their classification.^{[citation needed]}

Thomas was born in Woodington, Darke County, Ohio, to Harry and Harriet (née Wagner) Thomas. His father was a doctor and his mother a school teacher. In 1900, the family moved to the mining town of Victor, Colorado. There he worked as a gold miner, a cook, and a reporter on the newspaper.

In 1910, Thomas graduated from Victor High School, where one of his teachers was Mabel Barbee Lee. The following year, he graduated from Valparaiso University with bachelor's degrees in education and science. The next year he received both a B.A. and an M.A. from the University of Denver and began work for the Chicago Journal, writing for it until 1914. Thomas also was on the faculty of Chicago-Kent College of Law at Illinois Institute of Technology, where he taught oratory from 1912 to 1914. He then went to New Jersey, where he studied for a master's at Princeton University (he received the degree in 1916) and again taught oratory at the university.

Lester William Polsfuss (June 9, 1915 – August 13, 2009)—known as Les Paul—was an American jazz and country guitarist, songwriter and inventor. He was the inventor of the solid-body electric guitar which made the sound of rock and roll possible. He is credited with many recording innovations. Although he was not the first to use the technique, his early experiments with overdubbing (also known as sound on sound),delay effects such as tape delay, phasing effects and multitrack recording were among the first to attract widespread attention.

His innovative talents extended into his playing style, including licks, trills, chording sequences, fretting techniques and timing, which set him apart from his contemporaries and inspired many guitarists of the present day. He recorded with his wife Mary Ford in the 1950s, and they sold millions of records.

Among his many honors, Paul is one of a handful of artists with a permanent, stand-alone exhibit in the Rock and Roll Hall of Fame. He is prominently named by the music museum on its website as an "architect" and a "key inductee" along with Sam Phillips and Alan Freed.
