Found out a terrific actor and man whom I was lucky enough to be in one of my plays died this morning of #coronavirus. He wasn’t elderly. He was one of the most respected actors in New York: a beacon of fierce intelligence, dry wit & deep kindness on stage and off. A tragic loss.

There are actors whose names appear in the announcement of a play, and you instantly think, without knowing any details: This will be work worth seeing. Mark Blum was of that wonderful caliber. Made me believe, every time I saw him. It’s terrible to read of his death.

My uncle, Mark Blum, has been known on stage by many names to many people over the years. But to me, he was just Uncle Mark. As you can imagine, my family is devastated. Reading tweets and seeing how many people loved & respected him is more special than you will ever know. pic.twitter.com/PaB5X401Vq

One of our family of Mozart in the Jungle passed this morning from the corona virus. Mark Blum was a truly wonderful actor, but more importantly, was a funny sensitive, and beautiful man. RIP. – Malcolm pic.twitter.com/fapOBe6WYp

When I was in drama school Mark Blum was exactly the kind of actor I aspired to be: constantly employed, deeply respected, total mensch. Gutted to hear of his passing. His wife Janet Zarish was my acting teacher at NYU. They were the loveliest couple. My heart breaks for her. https://t.co/J7MvHutdge
