Elaine Stritch, you will be greatly missed! The legendary showbiz star died today at her home in Birmingham, Michigan at the age of 89. Stritch was a fixture in New York City until just last year, when she left her famous residence at the Carlyle Hotel in Manhattan to be closer to her family.

The news of the sassy Broadway singer and actress’s passing was instantly felt among her colleagues, friends, and fans in Hollywood. Many of them took to social media to express their condolences—from Mia Farrow, who played her daughter in Woody Allen’s September (1987), to her more recent co-star Alec Baldwin, who played her long-suffering son on the hit NBC comedy 30 Rock.

Famous for her incredible range, Stritch’s career began in the 1940s and lasted for nearly 70 years. She appeared in a slew of films and television shows, but the stage remained the place where she most shined. Whether in musicals, dramas or solo cabaret shows, she attracted audiences to her with her infamous voice and charisma.

One of Stritch’s most memorable appearances was in the Stephen Sondheim musical Company (1970), where she played a cynical society woman, saluting her peers with the anthem “The Ladies Who Lunch.” The performance not only garnered her a Tony Award, but it became her signature tune—she went on to sing it in her one-woman show Elaine Stritch at Liberty and at the White House for President Obama. And today it became a refrain for her passing.
