Henry Clay, Sr. (April 12, 1777 – June 29, 1852), was a lawyer, politician and skilled orator who represented Kentucky separately in both the Senate and in the House of Representatives. He served three different terms as Speaker of the United States House of Representatives and was also Secretary of State from 1825 to 1829.

Clay was a dominant figure in both the First and Second Party systems. As a leading war hawk, he favored war with Britain and played a significant role in leading the nation to war in 1812. Later he was involved in the "Corrupt Bargain" of 1824, after which he was appointed Secretary of State by newly elected President John Quincy Adams, earning the scorn of Andrew Jackson. He was the foremost proponent of the American System, fighting for an increase in tariffs to foster industry in the United States, the use of federal funding to build and maintain infrastructure, and a strong national bank. He opposed the annexation of Texas, fearing it would inject the slavery issue into politics. Clay also opposed the Mexican-American War and the "Manifest Destiny" policy of Democrats, which cost him votes in the close 1844 election.

Henry Clay Frick (December 19, 1849 – December 2, 1919) was an American industrialist, financier, and art patron. He founded the H. C. Frick & Company coke manufacturing company, was chairman of the Carnegie Steel Company, and played a major role in the formation of the giant U.S. Steel steel manufacturing concern. He also financed the construction of the Pennsylvania Railroad and the Reading Company, and owned extensive real estate holdings in Pittsburgh and throughout the state of Pennsylvania. He later built the historic neoclassical Frick Mansion (now a landmark building in Manhattan) and at his death donated his extensive collection of old master paintings and fine furniture to create the celebrated Frick Collection and art museum. Once known by his critics as “the most hated man in America,” — Portfolio.com named Frick one of the "Worst American CEOs of All Time"— he has long been vilified by the public and historians for his ruthlessness and lack of morality in business.

Frick was born in West Overton, Westmoreland County, Pennsylvania, U.S., a grandson of Abraham Overholt, the owner of the prosperous Overholt Whiskey distillery (see Old Overholt). Frick's father, John W. Frick, was unsuccessful in business pursuits. Henry Clay Frick attended Otterbein College for one year, but did not graduate. In 1871, at 21 years old, Frick joined two cousins and a friend in a small partnership, using a beehive oven to turn coal into coke for use in steel manufacturing, and vowed to be a millionaire by the age of thirty. The company was called Frick Coke Company.
