Into the 2000s, Musial would spend time with the Cardinals at spring training, thrilling veterans and rookies alike with his stories.
Ever ready, he performed the national anthem on his harmonica at least one opening day at Busch Stadium. Musial learned his music during overnight train trips in the 1940s and in the 1990s was a member of a trio known as "Geriatric Jazz" and collaborated on a harmonica instructional book.
Stanley Frank Musial was born in Donora, Pa., on Nov. 21, 1920, son of a Polish immigrant steelworker. He began his minor league career straight out of high school, in June 1938, and soon after married high school sweetheart Lillian Labash, with whom he had four children.
Musial fell in 1940 while trying to make a tough catch and hurt his left arm, damaging his pitching prospects. Encouraged by minor league manager Dickie Kerr to try playing the outfield, he did so well in 1941 that the Cardinals moved him up to the majors in mid-September — and he racked up a .426 average during the final weeks of the season.
In his best year, 1948, he had four five-hit games and batted .376, best in the National League. He also led his league that year in runs scored (135), hits (230), total bases (429), doubles (46), and triples (18).
In 1954, he set a major league record with five home runs in a doubleheader against the New York Giants. He hit .300 or better in 16 consecutive seasons and hit a record six home runs in All-Star play, including a 12th-inning, game-winning shot in 1955.
In 1962, at age 41, he batted .330 and hit 19 home runs. In his final game, on Sept. 29, 1963, he had two hits at Busch Stadium against the Reds and the Cardinals retired his uniform number.
He was active in business, too. He served as a director of the St. Louis-based Southwest Bank. He was co-owner of a popular St. Louis steakhouse, "Stan Musial and Biggie's," and a bowling alley with former teammate Joe Garagiola (leading to a bitter fallout that eventually got resolved). He later ran Stan the Man Inc., specializing in merchandise he autographed. Musial was known for handing out folded $1 bills.
A prominent Polish-American, he was a charter member of the National Polish-American Sports Hall of Fame and was warmly regarded by his ancestral country, which in 2000 dedicated Stan Musial Stadium in Kutno, Poland. Musial also was involved politically, campaigning for John F. Kennedy in 1960 and serving as Lyndon Johnson's director of the President's Council on Physical Fitness.
Musial's versatility was immortalized in verse, by popular poet of the times Ogden Nash, who in "The Tycoon" wrote of the Cardinals star and entrepreneur:
"And, between the slugging and the greeting,
To the bank for a directors' meeting.
Yet no one grudges success to Stan,
Good citizen and family man,
Though I would love to have his job
One half tycoon, one half Ty Cobb."
The Cardinals said Musial is survived by his four children, Richard, Gerry, Janet and Jean, as well as 11 grandchildren and 12 great grandchildren.
Musial's wife died in May 2012.
Funeral arrangements had not yet been finalized, the Cardinals said. The team set up a memorial site around one of Musial's statues at Busch Stadium.
