In the 1923 World Series, the New York Yankees beat the New York Giants in six games. This would be the first of the Yankees' 27 World Series championships (as of 2011). The home field alternated each game, a noted difference to the 2–3–2 format.

The Yankees opened their new Yankee Stadium in April on a home run by Babe Ruth, setting the tone for the season and this Series, in which Ruth hit three home runs along with drawing eight walks. In Game 2, second baseman, Aaron Ward hit a home run. The Giants' one bright spot was "Old Casey" Stengel, who hit game-winning homers in each of the two Giants' victories. In typically eccentric Stengel fashion, one of them was inside-the-park at the cavernous Yankee Stadium, and his shoe came loose during his run around the bases. Stengel was traded after the season, leading him to quip later in life, "It's a good thing I didn't hit three homers in three games, or McGraw would have traded me to the Three-I League!". A quarter century later, Stengel would take on the role of Yankees manager, and would guide the Bronx Bombers through one of their most successful eras.

The World Series is the annual championship series of Major League Baseball (MLB), played between the American League and National League champions since 1903. The winner of the World Series championship is determined through a best-of-seven playoff and awarded the Commissioner's Trophy. As the series is played in October, Major League Baseball also refers to it as the "Fall Classic". The most recent World Series was won by the St. Louis Cardinals, who defeated the Texas Rangers in 7 games in 2011.

The New York Yankees of the American League have played in 40 World Series and won 27, and the Oakland/Philadelphia Athletics have played in 14 and won 9. In the National League, the St. Louis Cardinals have played in 18 and won 11, while the San Francisco/New York Giants and Los Angeles/Brooklyn Dodgers have both appeared in 18 and won 6.

Until the formation of the American Association in 1882 as a second major league, the National Association of Professional Base Ball Players (1871–75) and then the National League (founded 1876) represented the top level of organized baseball in the United States. All championships went to whoever had the best record at the end of the season, without a postseason series being played. Starting in 1884 and going through 1890, the National League and the American Association faced each other in a series of games at the end of the season to determine an overall champion. These matchups were disorganized in comparison to the modern Series: games played ranged from as few as three in 1884 (Providence defeated New York 3 games to zero), to a high of 15 in 1887 (Detroit beat St. Louis 10 games to 5), and both the 1885 and 1890 Series ended in ties, each team having won three games with one tie game.

George Herman Ruth, Jr. (February 6, 1895 – August 16, 1948), best known as "Babe" Ruth and nicknamed "the Bambino" and "the Sultan of Swat", was an American baseball player who spent 22 seasons in Major League Baseball (MLB) playing for three teams (1914–1935). Known for his hitting brilliance, Ruth set career records for home runs (714), slugging percentage (.690), runs batted in (RBI) (2,217), and on-base plus slugging (OPS) (1.164). Ruth originally entered the major leagues with the Boston Red Sox as a starting pitcher, but after he was sold to the New York Yankees in 1919, he converted to a full time right fielder. He subsequently became one of the league's most prolific hitters and with his home run hitting prowess, he helped the Yankees win seven pennants and four World Series titles. Ruth retired in 1935 after a short stint with the Boston Braves, and the following year, he became one of the first five players to be elected into the National Baseball Hall of Fame.

Ruth was the first player to hit 60 home runs in one season (1927), a mark first eclipsed by Roger Maris in 1961 with 61. Ruth's lifetime record of 714 home runs stood until 1974 when it was surpassed by Hank Aaron. Unlike many power hitters, Ruth also hit for a high batting average: his .342 lifetime average is the tenth highest in baseball history, and in one season (1923) he batted .393, a Yankee record. Ruth dominated the era in which he played. He led the league in home runs during a season twelve times, slugging percentage and OPS thirteen times each, runs scored eight times, and RBIs six times. Each of those totals represents a modern record.

Henry Louis "Lou" or "Buster"Gehrig (June 19, 1903 – June 2, 1941) was an American baseball first baseman who played 17 seasons in Major League Baseball (MLB) for the New York Yankees (1923–1939). Gehrig set several major league records, including most career grand slams (23) and most consecutive games played (2,130). Gehrig is chiefly remembered for his prowess as a hitter and his durability, a trait which earned him his nickname "The Iron Horse", as well as the pathos of his farewell from baseball at age 36, when he was stricken with amyotrophic lateral sclerosis (ALS). Gehrig was elected to the Baseball Hall of Fame in 1939. In 1969 he was voted the greatest first baseman of all time by the Baseball Writers' Association, and was the leading vote-getter on the Major League Baseball All-Century Team, chosen by fans in 1999.

A native of New York City, he played for the Yankees until his career was cut short by ALS, a disorder now commonly known in the United States and Canada as Lou Gehrig's disease. Over a 15-season span from 1925 through 1939, he played in 2,130 consecutive games. This streak ended only when Gehrig became disabled by the fatal neuromuscular disease that claimed his life two years later. His streak, long considered one of baseball's few unbreakable records, stood for 56 years, until finally broken by Cal Ripken, Jr., of the Baltimore Orioles on September 6, 1995.

Harold Clayton Lloyd, Sr. (April 20, 1893 – March 8, 1971) was an American film actor and producer, most famous for his silent comedies.

Harold Lloyd ranks alongside Charlie Chaplin and Buster Keaton as one of the most popular and influential film comedians of the silent film era. Lloyd made nearly 200 comedy films, both silent and "talkies", between 1914 and 1947. He is best known for his "Glasses Character", a resourceful, success-seeking go-getter who was perfectly in tune with 1920s era America.

His films frequently contained "thrill sequences" of extended chase scenes and daredevil physical feats, for which he is best remembered today. Lloyd hanging from the hands of a clock high above the street in Safety Last! (1923) is one of the most enduring images in all of cinema.^{[citation needed]} Lloyd did many of these dangerous stunts himself, despite having injured himself in August, 1919 while doing publicity pictures for the Roach studio. An accident with a bomb mistaken as a prop resulted in the loss of the thumb and index finger of his right hand (the injury was disguised on future films with the use of a special prosthetic glove, though the glove often did not go by unnoticed).
