John Hillerman, the actor who made a career out of playing snooty types, including Tom Selleck’s fastidious estate caretaker Jonathan Quayle Higgins III on Magnum, P.I., died Thursday. He was 84.

Hillerman, who received four Emmy nominations in consecutive years for portraying Higgins and won in 1987, died at his home in Houston, family spokeswoman Lori De Waal told the Associated Press. She said the cause of death had not been determined.

Hillerman also appeared as Higgins on episodes of Murder, She Wrote and Simon & Simon.
