IN: Grace Brewster Murray Hopper (nee Murray; December 9, 1906 - January 1, 1992) was an American computer scientist and United States Navy rear admiral. One of the first programmers of the Harvard Mark I computer, she was a pioneer of computer programming who invented one of the first compiler related tools. She popularized the idea of machine-independent programming languages, which led to the development of COBOL, an early high-level programming language still in use today. Hopper had attempted to enlist in the Navy during World War II, but she was rejected by the military because she was 34 years of age and thus too old to enlist.

In 1949, Hopper became an employee of the Eckert-Mauchly Computer Corporation as a senior mathematician and joined the team developing the UNIVAC I. Hopper also served as UNIVAC director of Automatic Programming Development for Remington Rand. The UNIVAC was the first known large-scale electronic computer to be on the market in 1950, and was more competitive at processing information than the Mark I. When Hopper recommended the development of a new programming language that would use entirely English words, she "was told very quickly that [she] couldn't do this because computers didn't understand English." Her idea was not accepted for 3 years, and she published her first paper on the subject, compilers, in 1952. In the early 1950s, the company was taken over by the Remington Rand corporation, and it was while she was working for them that her original compiler work was done. The program was known as the A compiler and its first version was A-0. In 1952 she had an operational link-loader, which at the time was referred to as a compiler. She later said that "Nobody believed that," and that she "had a running compiler and nobody would touch it. They told me computers could only do arithmetic." She goes on to say that her compiler "translated mathematical notation into machine code. Manipulating symbols was fine for mathematicians but it was no good for data processors who were not symbol manipulators. Very few people are really symbol manipulators. If they are they become professional mathematicians, not data processors. It's much easier for most people to write an English statement than it is to use symbols. So I decided data processors ought to be able to write their programs in English, and the computers would translate them into machine code. That was the beginning of COBOL, a computer language for data processors. I could say "Subtract income tax from pay" instead of trying to write that in octal code or using all kinds of symbols. COBOL is the major language used today in data processing." In 1954 Hopper was named the company's first director of automatic programming, and her department released some of the first compiler-based programming languages, including MATH-MATIC and FLOW-MATIC.

did the company use univac for commercial purposes?

Answer the question at the end by quoting:

Bhatt was born on 15 March 1993 in Mumbai to Indian film director Mahesh Bhatt and actress Soni Razdan. Her father is of Gujarati descent and her mother is of Kashmiri and German ancestry. Director Nanabhai Bhatt is her paternal grandfather. She has an elder sister, Shaheen (born 1988) and two half-siblings, Pooja Bhatt and Rahul Bhatt.
Bhatt has performed playback singing for the song "Sooha Saaha" in Highway (2014). A. R. Rahman, the composer of the film, invited her to his music school to undergo training. In 2014, she sang the unplugged version of the song "Samjhawan", for the composers Sharib-Toshi, in Humpty Sharma Ki Dulhania. In 2016, she sang an alternate version of the song "Ikk Kudi", for the soundtrack of Udta Punjab, with her co-star Dosanjh. In addition to acting in films, Bhatt has performed at the Filmfare, Screen and Stardust award ceremonies, and has also participated in a stage show in Hong Kong alongside Varun Dhawan and Sidharth Malhotra. In 2013, she performed at a charity event with Dhawan, Malhotra, Aditya Roy Kapur, Shraddha Kapoor and Huma Qureshi to raise funds for the flood-affected victims of Uttarakhand. In August 2016, she performed in various cities of the United States as a part of the "Dream Team 2016" tour, alongside actors Dhawan, Malhotra, Kapur, Katrina Kaif, Parineeti Chopra, filmmaker Karan Johar, and singer Badshah. In 2013, Bhatt took part in a campaign for PETA to raise awareness about homeless animals. In 2017, Bhatt launched an ecological initiative named CoExist to raise awareness about the welfare of street animals. The following year, she collaborated with Facebook Live for a campaign named Find Your Green, to campaign for environmentalism. In 2014, Bhatt launched her own line of clothing for women in association with the online fashion portal Jabong.com; she described the collection to be "very simple" and "very me". She is also the celebrity endorser for a number of brands and products, including Coca-Cola, Garnier and Maybelline.

What is she currently working on?

In 2017, Bhatt launched an ecological initiative named CoExist to raise awareness about the welfare of street animals.

input: Levine made his Metropolitan Opera (the "Met") debut at age 28 on June 5, 1971, leading a June Festival performance of Tosca. Following further appearances with the company, he was named principal conductor of the Metropolitan Opera in February 1972. He became the Met's principal conductor in 1973, and its Music Director in 1975. In 1983, he served as conductor and musical director for the Franco Zeffirelli screen adaptation of La Traviata, which featured the Met orchestra and chorus members. He became the company's first artistic director in 1986, and relinquished the title in 2004. In 2005, Levine's combined salary from the Boston Symphony Orchestra and the Met made him the highest-paid conductor in the country, at $3.5 million. During Levine's tenure, the Metropolitan Opera orchestra expanded its activities into the realms of recording, and separate concert series for the orchestra and chamber ensembles from The Met Orchestra at Carnegie Hall. Levine led the Metropolitan Opera on many domestic and international tours. For the 25th anniversary of his Met debut, Levine conducted the world premiere of John Harbison's The Great Gatsby, commissioned especially to mark the occasion. On his appointment as general manager of the Met, Peter Gelb emphasized that Levine was welcome to remain as long as he wanted to direct music there. Levine was paid $2.1 million by the Met in 2010. Following a series of injuries that began with a fall (see below), Levine's subsequent health problems led to his withdrawal from many Metropolitan Opera conducting engagements. Following a May 2011 performance of Die Walkure, Levine formally withdrew from all conducting engagements at the Met. After two years of physical therapy, Levine returned to conducting with a May 2013 concert with the Metropolitan Opera Orchestra at Carnegie Hall. On September 25, 2013, Levine conducted his first Met performance since May 2011, in a revival production of Cosi fan tutte. Levine was scheduled to conduct three productions at the opera house and three concerts at Carnegie Hall in the 2013-14 season. On April 14, 2016, Met management announced that Levine would step down from his position as Music Director at the end of the 2015-16 season. Levine was paid $1.8 million by the Met for the 2015/16 season. He assumed the new title of Music Director Emeritus, which he held until December 2017, when in the wake of allegations that Levine had sexually abused four young men, the Met suspended its relationship with him and cancelled all his future scheduled performances with the company.
