Born in East St. Louis, Illinois as the youngest of nine children, Bauer was the son of an Austrianimmigrant, a bartender who had earlier lost his leg in an aluminum mill. With little money coming into the home, Bauer was forced to wear clothes made out of old feed sacks, helping shape his hard-nosed approach to life. (It was said that his care-worn face "looked like a clenched fist".)
While playing baseball and basketball at East St. Louis Central Catholic High School, Bauer suffered permanent damage to his nose, which was caused by an errant elbow from an opponent. Upon graduation in 1941, he was repairing furnaces in a beer-bottling plant when his brother Herman, a minor league player in the Chicago White Sox system, was able to get him a tryout that resulted in a contract with Oshkosh of the Class D Wisconsin State League.
Returning to East St. Louis, Bauer joined the local pipefitter's union, and he stopped by the local bar where his brother Joe Bauer worked. Danny Menendez, a scout for the New York Yankees, decided to sign him for a tryout with the Yankees' farm team in Quincy, Illinois. The terms of the contract were as follows: just $175 a month (with a $25 per month increase if he made the team) and a $250 bonus.
Batting .300 at Quincy and with the team's top minor league unit, the Kansas City Blues, Bauer eventually made his debut with the Yankees in September 1948.
In his 14-season Major League Baseball career, Bauer had a .277 batting average with 164 home runs and 703 runs batted in in 1,544 games played. Bauer played on seven World Series-winning New York Yankees teams, and he holds the World Series record for the longest hitting streak (17 games). Perhaps Bauer's most notable performance came in the sixth and final game of the 1951 World Series, where he hit a three-run triple. He also saved the game with a diving catch of a line drive by Sal Yvars for the final out. At the close of the 1959 season, Bauer was traded to the Kansas City Athletics in the trade that brought them the future home run king Roger Maris (1961). This deal is often cited among the worst examples of the numerous trades between the Yankees and the Athletics during the late 1950s – trades that were nearly always one-sided in favor of the Yankees.
In 1961, the year Maris broke Babe Ruth's single-season home run record, Bauer, at 38 years of age, was coming to the end of the line in his playing career. On June 19, Bauer was named as the playing-manager of the Athletics, and he retired as a player one month later. In Bauer's first stint as the Athletics' manager, through the end of the 1962 season, the Athletics won 107 games and lost 157 (0.405), and his teams finished ninth in the ten-team American League twice.
After his firing at the close of the 1962 campaign, Bauer spent the 1963 season as first-base coach of the Baltimore Orioles. He was elevated to manager at the end of the season, as the Orioles sought a firmer hand in command of the team. The move was successful: Baltimore contended aggressively for the 1964 American League pennant, finishing third, and then—bolstered by the acquisition of future Hall of Fame outfielder Frank Robinson—its first AL pennant and World Series championship in 1966. However, when the Orioles, hampered by an injury to Robinson and major off-years by a number of regulars and pitchers, finished in the second division in 1967 and then fell far behind the eventual champion Detroit Tigers in 1968, Bauer was dismissed as the manager on July 12, in favor of Earl Weaver, then the Orioles' first-base coach.
Weaver proceeded to forge a Hall of Fame career over the next 14½ years as the Orioles' pilot.
Bauer then returned to the Athletics, now based in Oakland, for the 1969 campaign. He was fired for the second and final time by Finley after bringing Oakland home second in the new American League West Division. Overall, his regular-season managerial record was 594-544 (0.522).
Bauer moved to the Kansas City area Prairie Village, Kansas in 1949 after playing with the Blues of 1947 and 1948. While there, he met and later married Charlene Friede, the club's office secretary. She died in July 1999.
The family's children attended St. Ann's Grade School in Prairie Village, then Bishop Miege High School in Shawnee Mission.
Hank owned and managed a liquor store in Prairie Village for a number of years after retirement from baseball.
Hank crawled on top of the Yankee dugout and searched the stands, looking for a fan who was shouting racial slurs at Elston Howard. When asked about the incident, Bauer explained simply, "Ellie's my friend".—Excerpt of the book "Clubhouse Lawyer", by Art Ditmar, former major league pitcher
Hank lost four prime years from his playing career due to his Marine service. This is heavy duty when you figure such a career is usually over when a player reaches his mid-thirties. This is something that does not bother Hank. "I guess I knew too many great young guys who lost everything out there to worry about my losing part of a baseball career", he says.—From the book Semper FI, MAC, by Henry Berry
Tommy Lasorda on Bauer: "This guy's tough. He had a face that looked like it'd hold two days of rain."
Bauer was a no-nonsense leader and could be unforgiving if he felt his teammates' off-the-field activities were hurting the Yankees' on-the-field performance. Pitcher Whitey Ford remembered how Bauer reacted when he thought players like Ford and Mantle were overindulging themselves after hours: He pinned me to the wall of the dugout one day and said, 'Don't mess with my money.'
