The Baltimore Sun recently reported that Robinson was in the late stages of a long illness.
That December, Robinson was the centerpiece in what would ultimately be one of the most lopsided trades in baseball history, going to Baltimore for pitchers Milt Pappas and Jack Baldschun and outfielder Dick Simpson.
"We are deeply saddened by this loss of our friend, colleague and legend, who worked in our game for more than 60 years".
The slugger won two Most Valuable Player awards, one with the Reds and one with the Baltimore Orioles, making him the only player to win an MVP in both the American and National League.
Robinson was the NL MVP with Cincinnati in 1961 and Baltimore in 1966.
Robinson was the first player to win an MVP Award in both the National and American Leagues. We didn't belong on the same field, you know. You want to say guys are as good?
Robinson was named the AL Manager of the Year with the Orioles in 1989 - the same year he took part in history by coaching against the Blue Jays' Cito Gaston in the first games featuring two black managers.
Known for his elite talent and intense demeanor, Robinson became a central figure in advancing Major League Baseball's integration of black players after Jackie Robinson broke the color barrier in 1947.
After he was traded to the Indians in 1974, he was named the team's player-manager in 1975.
Elected to the Baseball Hall of Fame in 1982 when he was first eligible, Robinson batted at least.300 in nine different seasons, had 2,943 career hits, drove in 1,812 runs and played on five pennant-winning teams. "Frank Robinson was not only one of the great players in an era where there were so many great players".
The Orioles confirmed Robinson's passing Thursday afternoon. He also managed the Orioles' Triple-A affiliate in Rochester for most of the 1978 season.
Major League Baseball (MLB) is the most historic professional sports league in the United States and consists of 30 member clubs in the USA and Canada, representing the highest level of professional baseball. "It wasn't that they didn't try". Robinson was sacked 37 games into the 1991 season. He became the first manager of the Washington Nationals after the franchise moved from Montreal for the 2005 season - the Nationals put him in their Ring of Honor, too.
He also served as MLB's executive vice president of baseball development, with his focus on increasing African-American participation in the sport.
In February 2014, Robinson visited the Orioles' spring training camp in Sarasota, Fla.
Notable quote: "The only reason I'm the first black manager is that I was born black". Hart complied with the assignment.
