Jessie Royce Landis

Jessie Royce Landis was born Jessie Medbury in Chicago, Illinois, to Paul, an orchestra musician, and Ella Medbury. As per Ancestry.com, "Royce" does not appear to have been her middle name by birth; her middle initial is cited as either "J." or "T". Her acting surname "Landis" derives from her first husband, although she was married twice more.

Landis was a stage actress for much of her career. In the 1950s, she began appearing in movies as a character actress, most notably in To Catch a Thief (1955), and North by Northwest (1959), both starring Cary Grant and directed by Alfred Hitchcock. In North by Northwest she played Grant's character's mother, and in To Catch a Thief and The Swan (1956), she played the mothers of Grace Kelly's characters. Landis also made many television appearances.

Landis's appearance in North by Northwest earned her publicity for portraying Cary Grant's mother despite claiming to be nearly a year younger. Landis listed 1904 as the year of her birth, a date now given by many printed biographies and online sources. However, in the tradition of many actresses, she had actually shaved years off her age – in this instance, eight. She appears in the 1900 U.S. Census as a 3-year-old born in November 1896, and so was seven years older than Grant.

Landis was married three times. Her third husband and widower was United States Army Major General John F. R. "Jeff" Seitz (died 1978). Her autobiography, titled You Won't Be So Pretty (But You'll Know More), was published in 1954. She had no children.

Landis died of cancer in Danbury, Connecticut on February 2, 1972, aged 75.
