Michael Henson, president and CEO of the Minnesota Orchestra, will step down in August, it was announced late Thursday.
Some viewed Henson's departure as setting the stage for the return of former music director Osmo Vänskä, who resigned last October but has indicated he might wish to come back.
Henson, who joined the orchestra in 2007, oversaw the $50 million Orchestra Hall renovation, and spearheaded $110 million in overall fundraising, but he became a divisive figure during the bitter, 16-month labor dispute that ended in January.
During the lockout, in the fall of 2012, the musicians issued a vote of no confidence in Henson.
Then-board chair Jon Campbell dismissed the criticism, calling Henson "the perfect leader at this challenging time" and saying he "has the full confidence of our board."
Gordon Sprenger, who took over as board chair in January, publicly praised Henson, but the board reportedly was divided on whether he should stay or go.
Henson addressed the orchestra's "serious financial challenges," Sprenger said in a statement Thursday, and he leaves it "secure, on more solid financial footing.
"It is never easy to be an agent of change," Sprenger said.
