George Washington (February 22, 1732 [O.S. February 11, 1731] – December 14, 1799) was the first President of the United States of America, serving from 1789 to 1797, and the dominant military and political leader of the United States from 1775 to 1799. He led the American victory over Great Britain in the American Revolutionary War as commander-in-chief of the Continental Army from 1775 to 1783, and presided over the writing of the Constitution in 1787. Washington became the first president, by unanimous choice, and oversaw the creation of a strong, well-financed national government that maintained neutrality in the wars raging in Europe, suppressed rebellion, and won acceptance among Americans of all types. His leadership style established many forms and rituals of government that have been used since, such as using a cabinet system and delivering an inaugural address. Washington is universally regarded as the "Father of his country."

Nathanael Greene (August 7 [O.S. July 27] 1742 – June 19, 1786, frequently misspelled Nathaniel) was a major general of the Continental Army in the American Revolutionary War. When the war began, Greene was a militia private, the lowest rank possible; he emerged from the war with a reputation as George Washington's most gifted and dependable officer. Many places in the United States are named for him. Greene suffered financial difficulties in the post-war years and died suddenly of sunstroke in 1786.

Nathanael was the son of a Quaker farmer and smith. Nathanael was born on Forge Farm at Potowomut in the township of Warwick, Rhode Island, on August 7, 1742 new style. His mother, Mary Mott, was his father's second wife. Though his father's sect discouraged "literary accomplishments," Greene educated himself, with a special study of mathematics and law. The Rev. Ezra Stiles, later president of Yale University, was a strong influence in the young Nathanael's life.

In 1770, Greene moved to Coventry, Rhode Island, to take charge of the family-owned forge (foundry), just prior to his father's death. There, he was the first to urge the establishment of a public school and in the same year he was chosen as a member of the Rhode Island General Assembly, to which he was re-elected in 1771, 1772 and 1775. It is debatable that he was a member of the General Assembly since there is no mention of his participation in his personal papers and because there were several of his contemporaries with the same name from Rhode Island. He sympathized strongly with the "Whig," or Patriot, element among the colonists.

Sidney K. "Sid" Meier (born February 24, 1954) is a Canadian-American programmer and designer of several popular strategy video games and simulation video games, most notably Civilization. Meier co-founded MicroProse in 1982 and is a Director of Creative Development for computer game developer Firaxis Games, which he co-founded with Jeff Briggs and Brian Reynolds in 1996. He has won several prestigious accolades for his contributions to the computer games industry.

Sid Meier was born in Sarnia, Ontario, Canada. He graduated from the University of Michigan.

Meier founded MicroProse together with Bill Stealey in 1982. MicroProse initially developed flight simulator video games, such as Silent Service and F-19 Stealth Fighter. In 1987, the company released Sid Meier's Pirates!, which also began a trend of placing Meier's name in the titles of his games. Meier later explained that the inclusion of his name was because of the dramatic departure in the design of Pirates! compared to the company's earlier games. Stealey decided that it would improve the company's branding, believing that it would make those who purchased the flight simulators more likely to play Pirates!. After the release of F-19 Stealth Fighter, Meier decided to focus on developing strategy games. He later said, "Everything I thought was cool about a flight simulator had gone into that game." Inspired by SimCity and Empire!, Meier created Railroad Tycoon and later the game series for which he is most widely recognized, Civilization, although he designed only the first installment. Meier eventually left MicroProse and in 1996 founded Firaxis Games along with veteran designer and gaming executive Jeff Briggs. Today Firaxis makes strategy games, many of which are follow-ups to Meier titles, such as Civilization V and Pirates!. In 1996 he was awarded US Patent 5,496,962 for a "System for Real-Time Music Composition and Synthesis" used in a product called "CPU Bach".
