Emmy-winning actor Reg E. Cathey, best known for his work on “The Wire” and “House of Cards,” has died. He was 59.

“The Wire” creator David Simon reported Cathey’s death on Friday.

“Reg Cathey, 1958-2018. Not only a fine, masterful actor — but simply one of the most delightful human beings with whom I ever shared some long days on set,” Simon tweeted. “On wit alone, he could double any man over and leave him thinking. Reg, your memory is a great blessing.”

Cathey was nominated three consecutive times for role as Freddy Hayes on “House of Cards” and grabbed a win in 2015. He is also known for his parts as Norman Wilson on “The Wire” and Martin Quern on “Oz.”
