Rita Lydig (born Rita Hernandez de Alba de Acosta, October 1875– October 27, 1929) was an American socialite regarded as "the most picturesque woman in America." She was photographed by Adolf de Meyer, Edward Steichen, and Gertrude Käsebier, sculpted in alabaster by Malvina Hoffman, and was painted by Giovanni Boldini and John Singer Sargent, among others. She also wrote one novel, Tragic Mansions (Boni & Liveright, 1927), under the name Mrs Philip Lydig, a society melodrama described as "emotionally moving and appealing" by The New York Times.
Rita de Acosta was born in New York City in 1875 to Ricardo de Acosta, a steamship-line executive of Cuban descent, and a Spanish mother, Micaela Hernández de Alba y de Alba, reputedly a relation of the Dukes of Alba. She had seven siblings: Joaquín, Enrique, Ricardo, Mercedes, Aida, Maria, and Ángela.
Her sister Mercedes de Acosta, a lover of movie star Greta Garbo, was an author, a scriptwriter, and social critic. Another sister, Aida de Acosta, became the first female to fly a powered aircraft solo.
Rita de Acosta was married twice:
In 1921 Lydig announced her engagement to Reverend Percy Stickney Grant, rector of the Church of the Ascension. Their wedding plans were broken off in 1924 when Bishop William Manning refused to authorise the marriage, citing Lydig being a divorcée with two living former husbands. Rev. Grant died shortly afterwards, leaving his personal fortune to the woman he had hoped to marry, and Lydig spent large sums of money on fashion, art, furniture, and other objects to overcome her grief. Heavily in debt, she was forced to sell her Washington Square home and its contents, was declared bankrupt, and died of pernicious anaemia at the Gotham Hotel shortly after, at the age of 54.
