Question:
Hattie McDaniel (June 10, 1895 - October 26, 1952) was an American stage actress, professional singer-songwriter, and comedian. She is best known for her role as "Mammy" in Gone with the Wind (1939), for which she won the Academy Award for Best Supporting Actress, the first Academy Award won by an African American entertainer. In addition to acting in many films, McDaniel was a radio performer and television star; she was the first black woman to sing on radio in the United States. She appeared in over 300 films, although she received screen credits for only 80 or so.
The whereabouts of McDaniel's Oscar are currently unknown. In 1992, Jet magazine reported that Howard University could not find it and alleged that it had disappeared during protests in the 1960s. In 1998, Howard University stated that it could find no written record of the Oscar having arrived at Howard. In 2007, an article in the Huffington Post repeated rumors that the Oscar had been cast into the Potomac River by angry civil rights protesters in the 1960s. The assertion reappeared in the Huffington Post under the same byline in 2009. In 2010, Mo'Nique, the winner of the Academy Award for Best Supporting Actress, wearing a blue dress and gardenias in her hair, as McDaniel had at the ceremony in 1940, in her acceptance speech thanked McDaniel "for enduring all that she had to so that I would not have to". Her speech revived interest in the whereabouts of McDaniel's plaque. In 2011, J. Freedom duLac reported in the Washington Post that the plaque had disappeared in the 1960s. In November 2011, W. B. Carter, of the George Washington University Law School, published the results of her year-and-a-half-long investigation into the Oscar's fate. Carter rejected claims that students had stolen the Oscar (and thrown it in the Potomac River) as wild speculation or fabrication that traded on long-perpetuated stereotypes of blacks. She questioned the sourcing of the Huffington Post stories. Instead, she argued that the Oscar was likely returned to Howard University's Channing Pollack Theater Collection between the spring of 1971 and the summer of 1973 or had possibly been boxed and stored in the drama department at that time. The reason for its removal, she argued, was not civil rights unrest but rather efforts to make room for a new generation of black performers. If neither the Oscar nor any paper trail of its ultimate destiny can be found at Howard today, she suggested, inadequate storage or record-keeping in a time of financial constraints and national turbulence may be blamed. She also suggested that a new generation of caretakers may have failed to realize the historic significance of the 5 1/2" x 6" plaque.

what was the oscar for?

Answer:

input: Devika Rani Chaudhuri was born into a Bengali family in Waltair near Visakhapatnam in present-day Andhra Pradesh, into an extremely affluent and educated Bengali family. Her father, Colonel Manmatha Nath Chaudhuri, was the first Indian Surgeon-General of Madras Presidency and a nephew of Rabindranath Tagore. Her mother, Leela Devi Choudhary, came from an educated family and was a grand-niece of Tagore. Devika's father's brothers were Ashutosh Chaudhuri, Chief Justice of Calcutta High Court, Jogesh Chandra Chaudhuri, a prominent Kolkata-based barrister and Pramatha Chaudhuri, the famous Bengali writer. Devika Rani was related through both her parents to the poet and Nobel Laureate Rabindranath Tagore. Her father, Manmathnath Choudhary, was the son of Sukumari Devi Choudhary, sister of Rabindranath Tagore. Devika's mother, Leela Devi Chaudhuri, was the daughter of Indumati Devi Chattopadhyay, whose mother Saudamini Devi Gangopadhyay was another sister of the Nobel laureate. Devika's father and maternal grandmothers were first cousins to each other, being the children of two sisters of Rabindranath Tagore. Further, two of her father's brothers had also married their cousins: Prativa Devi Choudhury, wife of Ashutosh Choudhary, was the daughter of Hemendranath Tagore, and Indira Devi Choudhary, wife of Promatho Choudhary, was the daughter of Satyendranath Tagore. Devika thus had strong ties to Jarasanko, seat of the Tagore family in Kolkata and a major crucible of the Bengali renaissance. Devika Rani was sent to boarding school in England at the age of nine, and grew up there. After completing her schooling in the mid-1920s, she enrolled in the Royal Academy of Dramatic Art (RADA) and the Royal Academy of Music in London to study acting and music. She also enrolled for courses in architecture, textile and decor design, and even apprenticed under Elizabeth Arden. All of these courses, each of them a few months long, were completed by 1927, and Devika Rani then took up a job in textile design.

Answer the question at the end by quoting:

Born in Prague, Czech Republic (then part of the Austro Hungarian empire) Friml showed aptitude for music at an early age. He entered the Prague Conservatory in 1895, where he studied the piano and composition with Antonin Dvorak. Friml was expelled from the conservatory in 1901 for performing without permission.
Friml wrote his most famous operettas in the 1920s. In 1924, he wrote Rose-Marie. This operetta, on which Friml collaborated with lyricists Oscar Hammerstein II and Otto Harbach and co-composer Herbert Stothart, was a hit worldwide, and a few of the songs from it also became hits including "The Mounties" and "Indian Love Call". The use of murder as part of the plot was ground-breaking among operettas and musical theatre pieces at the time. After Rose-Marie's success came two other hit operettas, The Vagabond King in 1925, with lyrics by Brian Hooker and William H. Post, and The Three Musketeers in 1928, with lyrics by P. G. Wodehouse and Clifford Grey, based on Alexandre Dumas's famous swashbuckling novel. In addition, Friml contributed to the Ziegfeld Follies of 1921 and 1923. Friml wrote music for many films during the 1930s, often songs adapted from previous work. The Vagabond King, Rose-Marie and The Firefly were all made into films and included at least some of Friml's music. Oddly enough, his operetta version of The Three Musketeers was never filmed, despite the fact that the novel itself has been filmed many times. In 1930, he wrote a new operetta score for film, The Lottery Bride. Like his contemporary, Ivor Novello, Friml was sometimes ridiculed for the sentimental and insubstantial nature of his compositions and was often called trite. Friml was also criticized for the old-fashioned, Old World sentiments found in his works. Friml's last stage musical was Music Hath Charms in 1934. During the 1930s, Friml's music fell out of fashion on Broadway and in Hollywood.

What was his greatest piece he released?
In 1924, he wrote Rose-Marie.
