Jay Hanna "Dizzy" Dean (January 16, 1910 – July 17, 1974) was an American professional baseball player. He played in Major League Baseball as a pitcher for the St. Louis Cardinals, Chicago Cubs and the St. Louis Browns. A brash and colorful personality, Dean was the last National League pitcher to win 30 games in one season. After his playing career, he became a popular television sports commentator. Dean was elected to the Baseball Hall of Fame in 1953.

Dean was best known for leading the 1934 "Gashouse Gang" St. Louis team. He had a 30–7 record with a 2.66 ERA during the regular season. His brother, Paul, was also on the roster, and was nicknamed "Daffy", although this was usually only done for press consumption. Though "Diz" sometimes called his brother "Daf", he typically referred to himself and his brother as "Me an' Paul".

The Gashouse Gang was the southernmost and westernmost team in the major leagues at the time, and became a de-facto "America's Team." Team members, particularly Southerners such as the Dean brothers and Pepper Martin, became folk heroes in Depression-ravaged America. Americans saw in these players, dirty and hustling rather than handsome and graceful, a spirit of hard work and perseverance, as opposed to the haughty, highly-paid New York Giants, whom the Cardinals chased for the National League pennant.

Leo Ernest Durocher (in French Léo Ernest Durocher) (July 27, 1905 – October 7, 1991), nicknamed Leo the Lip, was an American infielder and manager in Major League Baseball. Upon his retirement, he ranked fifth all-time among managers with 2,009 career victories, second only to John McGraw in National League history. Durocher still ranks tenth in career wins by a manager. A controversial and outspoken character, Durocher's career was dogged by clashes with authority, umpires (his 95 career ejections as a manager trailed only McGraw when he retired, and still rank fourth on the all-time list), and the press.

Durocher was elected to the Baseball Hall of Fame in 1994.

Born in West Springfield, Massachusetts to a French-Canadian family, Durocher joined the New York Yankees briefly in 1925 before rejoining the club in 1928 as a regular, if unspectacular, player. Babe Ruth nicknamed him "The All-American Out."

Durocher was a favorite of Yankee manager Miller Huggins, who saw in him the seeds of a great manager – the competitiveness, the passion, the ego, the facility for remembering situations. Durocher's outspokenness did not endear him to Yankee ownership, however, and his habit of passing bad checks, to finance his expensive tastes in clothes and nightlife, annoyed Yankee general manager Ed Barrow.

Tyrus Raymond "Ty" Cobb (December 18, 1886 – July 17, 1961), nicknamed "The Georgia Peach," was an American Major League Baseball outfielder. He was born in Narrows, Georgia. Cobb spent 22 seasons with the Detroit Tigers, the last six as the team's player-manager, and finished his career with the Philadelphia Athletics. In 1936, Cobb received the most votes of any player on the inaugural Baseball Hall of Fame ballot, receiving 222 out of a possible 226 votes.

Cobb is widely credited with setting 90 Major League Baseball records during his career. He still holds several records as of 2012, including the highest career batting average (.366 or .367, depending on source) and most career batting titles with 11 (or 12, depending on source). He retained many other records for almost a half century or more, including most career hits until 1985 (4,189 or 4,191, depending on source), most career runs (2,245 or 2,246 depending on source) until 2001, most career games played (3,035) and at bats (11,429 or 11,434 depending on source) until 1974, and the modern record for most career stolen bases (892) until 1977. He committed 271 errors in his career, the most by any American League outfielder.

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.
