Martin Mull, who played Roseanne, died at the age of 80.

Martin Mull died on Thursday, June 27th, after being sick for a long time. He was 80 years old. Television Line says that his daughter Maggie shared the sad news on Instagram:

“It breaks my heart to say that my father died at home on June 27th, after a brave battle with a long illness.” He was famous for being great at all kinds of creative tasks and for making commercials for Red Roof Inn. That joke would make him laugh. He was always funny. Friends, coworkers, fellow artists, comedians, musicians, and, most importantly, many, many dogs will miss my dad very much. His wife and daughter will also miss him a lot. I loved him very much.”

Martin was best known for his time on the show Roseanne as Leon Carp, Roseanne’s rude boss from 1991 to 1997. He then played Mr. Kraft, Sabrina’s annoying and rule-following principal, on Sabrina the Teenage Witch, which starred Melissa Joan Hart. Martin was there from Seasons 2 to 4, and he also played lead roles on Veep and Arrested Development. The second one got him nominated for an Emmy. When his former co-stars heard the news of his death, they spoke out right away in his honor.
