Garson’s first Hollywood production, Goodbye, Mr. Chips (1939), won her an Academy Award nomination. This began a remarkable run of five more Oscar nominations during the first half of the 1940s for her leading roles in Blossoms in the Dust (1941), Mrs. Miniver (1942), Madame Curie (1943), Mrs. Parkington (1944), and The Valley of Decision (1945). In 1942 she earned her only Oscar for playing the title role in Mrs. Miniver. Her portrayal of a British homemaker on the home front during World War II was a particular favorite of Winston Churchill and Franklin D. Roosevelt. Her remarks upon accepting the Oscar the longest recorded acceptance speech (5.5 minutes in length) in the Academy’s history, which afterward prompted organizers to place a cap on them. After her role in Madame Curie, which featured the popular pairing of Garson with actor Walter Pidgeon, she was pictured on the cover of Time magazine. Garson was honored as Hollywood’s most popular star in polls within the United States and throughout the world in 1944. Her star was waning, however, by the later 1940s. During the 1950s her movie efforts were regarded mostly with disappointment. Garson negotiated the end of her contract with MGM in 1953 after playing a small role in the blockbuster production of Julius Caesar. She made occasional television performances and in 1958 made her Broadway debut in Auntie Mame. Garson’s portrayal of Eleanor Roosevelt in the 1960 movie Sunrise at Campobello earned her a final Oscar nomination.
Garson’s first marriage, to Edward Snelson in 1933, ended in divorce in 1940. In 1943 she married Richard Ney, who had played her son in Mrs. Miniver; the couple divorced in 1947. Garson's third and final marriage, this time to Texas millionaire oil executive and rancher E. E. “Buddy” Fogelson, occurred on July 15, 1949. The union lasted nearly forty years and only ended with Fogelson’s death from Parkinson’s disease in 1987. It was Fogelson who brought Garson to Texas, and she remained connected to Dallas for the rest of her life, although she split her time between Los Angeles and the ranch they shared near Pecos, New Mexico. Garson retired from acting permanently in 1980. During these years Garson was a generous financier and benefactor to the arts, with Dallas being the recipient of many of her greatest contributions. Garson donated millions of dollars to Southern Methodist University in Dallas and funded the Greer Garson Theatre (part of the Meadows School of the Arts) which opened in 1992. Because of her late husband's fight with Parkinson's, Garson had a strong desire to use her name and celebrity status to kindle public awareness of various medical conditions that needed the support of the community in order to make advancements and/or breakthroughs that could only be facilitated through research dollars. By the early 1990s, Garson, a valiant spokeswoman, championed these initiatives at the Texas Health Presbyterian Hospital in Dallas, Texas. The Texas Health Presbyterian Foundation’s most recognized fund-raising event is the annual Greer Garson Gala, a signature event that seeks to raise money and support for programs and services of the hospital. Garson was a zealous healthcare advocate and vociferous supporter of medical research, healthcare, and education. On April 6, 1996, at Presbyterian Hospital in Dallas, Texas, Greer Garson passed away in the company of her close friend, pianist Van Cliburn. She was buried at the Sparkman Hillcrest Memorial Park in Dallas. Garson's epitaph on her gravestone is a testament to her legacy: A Dignified Lady of Grace and Beauty/Her Wit, Charm and Talent/Thrilled the World and Touched/All Who Knew Her. Source
