"You could go toe-to-toe, face-to-face and cheek-to-cheek with him," former Oriole outfielder Don Buford said, "and, no matter what, the next day it was forgotten. That was outstanding."
Born Aug. 14, 1930, in St. Louis, Weaver was an undersized but talented teenager who played second base in high school.
After eight years in the minor leagues, Weaver realized he would never reach the majors and turned to managing, according to the 2002 book he co-wrote, "Weaver on Strategy."
He spent about half of his 20 years in the minors as a manager "who was just happy to be in baseball," Weaver said in his Hall of Fame induction speech.
Soon after joining the Orioles as a first-base coach in 1968, he became the manager.
His famous feud with Palmer dated to the 1970s, when they would exchange barbs on the mound and in print. They clearly grated on each other but there also was a grudging mutual respect between two dynamic personalities who were integral to the Orioles' winning chemistry.
"Did he make my life difficult ... yes," Palmer said. "Did I make his life difficult sometimes ... of course ... and sometimes you did it for entertainment value."
They occasionally sparred good-naturedly on the banquet circuit after both left the field, but carried on a largely cordial relationship until the feud bubbled up during an ugly incident at a 2000 banquet.
Several former Orioles stars were on hand to roast Weaver, but Palmer's allusions to the diminutive former manager's size and drinking habits struck a nerve. When Weaver got his chance to fire back, he ripped into Palmer, calling him an idiot and an egotist who often had little stomach for pitching with discomfort. The nasty scene ended with Weaver being led away by former Orioles first baseman Lee May and Orioles coach Elrod Hendricks.
"It was unfortunate because these two men have such great respect for each other," Hendricks said at the time.
It was in keeping with Weaver's quick temper, which got him ejected from major league games 98 times.
His animated disagreements with umpires often ended with a red-faced Weaver hurling away his hat or kicking dirt on the ump's shoes.
"Earl was Earl," Palmer said, "but once you were an Oriole, you played because winning was a lot of fun and Earl was all about winning."
Weaver had three children from his first marriage, which ended in divorce. Survivors include his second wife, Marianna, whom he married in 1964.
