Andrew Carnegie ( kar-NAY-gee, but commonly KAR-n@-ghee or kar-NEG-ee; November 25, 1835 - August 11, 1919) was a Scottish-American industrialist, business magnate, and philanthropist. Carnegie led the expansion of the American steel industry in the late 19th century and is often identified as one of the richest people (and richest Americans). He became a leading philanthropist in the United States and in the British Empire. During the last 18 years of his life, he gave away about $350 million to charities, foundations, and universities--almost 90 percent of his fortune.
Carnegie did not want to marry during his mother's lifetime, instead choosing to take care of her in her illness towards the end of her life. After she died in 1886, the 51-year-old Carnegie married Louise Whitfield, who was 21 years his junior. In 1897, the couple had their only child, a daughter, whom they named after Carnegie's mother, Margaret. Carnegie made his fortune in the steel industry, controlling the most extensive integrated iron and steel operations ever owned by an individual in the United States. One of his two great innovations was in the cheap and efficient mass production of steel by adopting and adapting the Bessemer process, which allowed the high carbon content of pig iron to be burnt away in a controlled and rapid way during steel production. Steel prices dropped as a result, and Bessemer steel was rapidly adopted for rails; however, it was not suitable for buildings and bridges. The second was in his vertical integration of all suppliers of raw materials. In the late 1880s, Carnegie Steel was the largest manufacturer of pig iron, steel rails, and coke in the world, with a capacity to produce approximately 2,000 tons of pig metal per day. In 1883, Carnegie bought the rival Homestead Steel Works, which included an extensive plant served by tributary coal and iron fields, a 425-mile (684 km) long railway, and a line of lake steamships. Carnegie combined his assets and those of his associates in 1892 with the launching of the Carnegie Steel Company. By 1889, the U.S. output of steel exceeded that of the UK, and Carnegie owned a large part of it. Carnegie's empire grew to include the J. Edgar Thomson Steel Works in Braddock, (named for John Edgar Thomson, Carnegie's former boss and president of the Pennsylvania Railroad), Pittsburgh Bessemer Steel Works, the Lucy Furnaces, the Union Iron Mills, the Union Mill (Wilson, Walker & County), the Keystone Bridge Works, the Hartman Steel Works, the Frick Coke Company, and the Scotia ore mines. Carnegie, through Keystone, supplied the steel for and owned shares in the landmark Eads Bridge project across the Mississippi River at St. Louis, Missouri (completed 1874). This project was an important proof-of-concept for steel technology, which marked the opening of a new steel market.

Cosby was born on July 12, 1937 in Philadelphia, Pennsylvania. He is one of four sons of Anna Pearl (nee Hite), a maid, and William Henry Cosby Sr., who served as a mess steward in the U.S. Navy. During much of Cosby's early childhood, his father was away from home in Navy service and especially during WWII. As a student, he described himself as a class clown.
In 1965, Cosby was cast alongside Robert Culp in the I Spy espionage adventure series on NBC. I Spy became the first weekly dramatic television series to feature an African-American in a starring role. At first, Cosby and NBC executives were concerned that some affiliates might be unwilling to carry the series. At the beginning of the 1965 season, four stations declined the show; they were in Georgia, Florida, and Alabama. Viewers were taken with the show's exotic locales and the authentic chemistry between the stars, and it became one of the ratings hits of that television season. I Spy finished among the twenty most-watched shows that year, and Cosby would be honored with three consecutive Emmy Awards for Outstanding Lead Actor in a Drama Series. When accepting his third Emmy for the show, Cosby told the audience: "Let the message be known to bigots and racists that they don't count!" During the series run, Cosby continued to do standup comedy performances and recorded a half dozen record albums for Warner Bros. Records. He also began to dabble in singing, recording Silver Throat: Bill Cosby Sings in 1967. In June 1968, Billboard reported that Cosby had turned down a five-year, US$3.5 million contract renewal offer and would leave the label in August that year to record for his own record label. In July 1968, Cosby narrated "Black History: Lost, Stolen, or Strayed", a CBS documentary addressing the representation of blacks in popular culture. Andy Rooney wrote the Emmy awarded script for Bill Cosby to read. Michael Eric Dyson said it was one of "the rare exceptions when Cosby took off the gloves and blinders, to discuss race in public with candor and discernment." Due to its popularity and controversial nature, it was rebroadcast less than a month later. Tetragrammaton Records was a division of the Campbell, Silver, Cosby (CSC) Corporation, the Los Angeles-based production company founded by Cosby, his manager Roy Silver, and filmmaker Bruce Post Campbell. It produced films as well as records, including Cosby's television specials, the Fat Albert cartoon special and series and several motion pictures. CSC hired Artie Mogull as President of the label and Tetragrammaton was fairly active during 1968-69 (its most successful signing was British heavy rock band Deep Purple) but it quickly went into the red and ceased trading during 1970.
