Just devastated to learn that the magnificent Brian Dennehy has died. They is no one i enjoyed working with more. And there are few friends as valued in my life. I took this photo backstage when we were in Love Letters. He loved my pup Bowie.

Kevin M. Kruse:

First thing I thought of when I heard Brian Dennehy had died was the story @pattonoswalt tells about meeting him at a buffet table.

"Character actors! Who cares if we get fat?!"

Lin-Manuel Miranda:

Was lucky enough to see Brian Dennehy twice on stage, masterful in Love Letters, and monumentally heartbreaking in Death Of A Salesman. A colossus. What a loss.

Dana Delany:

I met Brian in a bar, acted in a movie with him but the stage was what he loved. In rehearsal he said, “This is it, kid.” He was a fellow nutmegger, mick and a Marine. They don’t make his kind anymore. ❤️to his family.

Brian Dennehy's Irish roots

In 2010, Aliah O’Neill spoke with Dennehy about his Irish roots in a piece for Irish America Magazine, sister publication to IrishCentral: “Dennehy’s Irish roots extend to the West and Southwest of Ireland on both sides of his family – on his father’s side, his grandfather was born in Millstreet, County Cork, and his grandmother was born in Kilmacalogue in West Cork. 

“Dennehy said his ancestors 'were born back in the 1850s or 1860s and were essentially farmworkers, and my grandfather emigrated I’m guessing sometime around 1900 – 1904, 1905, he was very young. All of his brothers and sisters eventually came to America and they were all factory workers – they worked for a major factory in Bridgeport, Connecticut called Jenkin’s Valve, which is no longer there.'”

“On Dennehy’s mother’s side were the Mannions. His grandmother emigrated from Waterford and became a domestic in the United States, a few generations earlier than his father’s people. Most of his relatives settled in Bridgeport and Danbury.

“Like O’Neill’s father James, who was born in Kilkenny during the worst year of the Great Famine, 1847, Dennehy’s paternal grandfather refused to return to Ireland in his later years. 'My grandfather who was an immigrant under the worst conditions didn’t go back and never wanted to go back, refused to go back, he was so bitter about his experiences as a child. I think most Irish Americans have forgotten how difficult it was for those people. But I can still remember his scars about that. That’s something that we shouldn’t forget…how difficult it was in the 1880s and the 1890s and before.'"
