Eunice Elizabeth Sargaison (17 March 1928 – 8 June 2018), known professionally as Eunice Gayson, was an English actress best known for playing Sylvia Trench, James Bond's love interest in the first two Bond films (Dr. No and From Russia with Love) and is thus considered to have been the first "Bond girl". Appearing in this capacity in two movies, she was unique in this regard until Lea Seydoux (as Madeleine Swann) in Spectre and No Time To Die nearly 60 years later.
