Conchata Ferrell’s passing has caused Jon Cryer to reminisce about their time together on Two and a Half Men.

On Tuesday, the 55-year-old actor paid tribute to Ferrell, who played the CBS sitcom’s maid Berta, calling her a “wonderful human.”

“Berta’s nasty temperament was made up by the writers.” Chatty’s genuine virtues, according to him, were her warmth and openness. “I’m grieving for the woman I’ll miss and the happiness she brought to so many.”

Cryer first met Ferrell on Two and a Half Men in the second episode, and he commented, “I was so happy that they’d been able to place her on the show.” When I informed her I was a huge fan of hers, she just refused to believe me.”

“I had to reprise one of my favorite scenes from a canceled mid-’70s sitcom called ‘Hot L Baltimore,’” he said before she realized what he meant. I’m pleased I was fully aware of how lucky I was to be on stage with her.”

“I treasured every moment and will continue to do so till we cross paths again.” “I’m guessing she’ll call me Zippy,” Cryer remarked of the character’s nickname on the show.

Cryer recommended that people “check out” Ferrell’s “great body of film work,” which includes Edward Scissorhands, Erin Brockovich, Network, and Heartland.

“My heartfelt condolences go out to Arnie, Samantha, her family, and the countless UCLA students whose lives she impacted,” he continued.

Ferrell died on Monday at the age of 77 after complications from a heart attack, according to Deadline. She died in Sherman Oaks Hospital in Sherman Oaks, California, surrounded by her family.

PEOPLE reached out to Ferrell’s representative, who did not immediately respond.

According to her husband, Arnie Anderson, the actress was admitted to the hospital in May after becoming ill. Ferrell was in the intensive care unit for more than four weeks and experienced a cardiac arrest once, which Anderson believed lasted around ten minutes. Ferrell was unable to communicate or speak and was placed on a respirator and dialysis before being transferred to a long-term care facility.

The actress told TMZ in February that she had been staying at her holiday home in Charleston, West Virginia, since Thanksgiving, when she was rushed to the hospital in December with a kidney disease.

She claimed that the illness became more severe as it spread and into her circulation. Ferrell was in the intensive care unit for several weeks before being discharged and placed in transitional care in January. She recovered at home while bedridden for a month, receiving physical therapy multiple times every day.

The actress told the publication that her spouse was there for her during the ordeal and did everything he could to look after her.
