CHICAGO (WLS) -- Margie Korshak, Chicago's famed publicist to the stars, died at 86 years old on Sunday morning, her family said.
Her family said she died at her home in the city's Gold Coast neighborhood after suffering from kidney failure.
Korshak, born in 1939, launched the public relations firm that bears her name more than 50 years ago.
Her company's clients include Broadway In Chicago.
"Margie helped shape hundreds of productions and careers-including ours. She was a brilliant strategist and a champion of Broadway In Chicago," said President and CEO of Broadway In Chicago Lou Raizin.
"Margie's presence was larger than life-her laughter unmistakable, her instincts unparalleled. She was one of a kind and fiercely loyal," recalled longtime friend Vice President of Broadway In Chicago and Eileen LaCario.
Korshak was known for making connections with both Hollywood and Chicago luminaries, like former First Lady Michelle Obama.
