Years earlier, she appeared as school teacher Miss Parker in the film Spencer's Mountain – an earlier adaptation of the Earl Hamner stories on which The Waltons was based. Gregg may be best remembered for her many appearances in Dragnet. Jack Webb used her in dozens of roles on both the radio and TV versions of the show, as well as in the 1954 film version of Dragnet. In later years, she appeared on other shows produced by Webb's production company, Mark VII Limited (e.g. Adam-12 and Emergency!). Voice acting Gregg was the voice for Riabouchinska, the ventriloquist doll, in the 1956 Alfred Hitchcock Presents TV episode "And So Died Riabouchinska". Gregg supplied the voice of Mrs. Bates in Psycho (1960), as did Jeanette Nolan and Paul Jasmin, all uncredited. Only Gregg did the voice in the sequels Psycho II and Psycho III. She voiced Tarra on the 1967 animated TV series The Herculoids. She reprised that role when the series was revived in 1981 as part of the Space Stars animated series. Personal life Gregg married producer Jaime del Valle in 1948 (another source says October 15, 1947, in Las Vegas, Nevada). They had three children, Gregg, Jaime, and Ricardo. They were divorced on December 22, 1959. Gregg was active with Recording for the Blind, making recordings as a volunteer and serving on the group's board of directors. Death Gregg died from lung cancer in Encino, California, on September 15, 1986, aged 70.
