Some context: Vladimir Vladimirovich Nabokov (; Russian: Vladimir Vladimirovich Nabokov, pronounced [vla'djimjIr na'bok@f] ( listen), also known by the pen name Vladimir Sirin; 22 April [O.S. 10 April] 1899 - 2 July 1977) was a Russian-American novelist, translator and entomologist.
The Nabokovs settled in Manhattan and Vladimir began volunteer work as an entomologist at the American Museum of Natural History.  Nabokov joined the staff of Wellesley College in 1941 as resident lecturer in comparative literature. The position, created specifically for him, provided an income and free time to write creatively and pursue his lepidoptery. Nabokov is remembered as the founder of Wellesley's Russian Department. The Nabokovs resided in Wellesley, Massachusetts, during the 1941-42 academic year. In September 1942 they moved to Cambridge where they lived until June 1948. Following a lecture tour through the United States, Nabokov returned to Wellesley for the 1944-45 academic year as a lecturer in Russian. In 1945, he became a naturalized citizen of the United States. He served through the 1947-48 term as Wellesley's one-man Russian Department, offering courses in Russian language and literature. His classes were popular, due as much to his unique teaching style as to the wartime interest in all things Russian. At the same time he was the de facto curator of lepidoptery at Harvard University's Museum of Comparative Zoology. After being encouraged by Morris Bishop, Nabokov left Wellesley in 1948 to teach Russian and European literature at Cornell University, where he taught until 1959. Among his students at Cornell was future U.S. Supreme Court Justice Ruth Bader Ginsburg, who later identified Nabokov as a major influence on her development as a writer.  Nabokov wrote Lolita while travelling on butterfly-collection trips in the western United States that he undertook every summer. Vera acted as "secretary, typist, editor, proofreader, translator and bibliographer; his agent, business manager, legal counsel and chauffeur; his research assistant, teaching assistant and professorial understudy"; when Nabokov attempted to burn unfinished drafts of Lolita, it was Vera who stopped him. He called her the best-humored woman he had ever known.  In June 1953 Nabokov and his family went to Ashland, Oregon. There he finished Lolita and began writing the novel Pnin. He roamed the nearby mountains looking for butterflies, and wrote a poem called Lines Written in Oregon. On 1 October 1953, he and his family returned to Ithaca, New York, where he would later teach the young writer Thomas Pynchon.

Some context: Laura Nyro ( NEER-oh; born Laura Nigro, October 18, 1947 - April 8, 1997) was an American songwriter, singer, and pianist. She achieved critical acclaim with her own recordings, particularly the albums Eli and the Thirteenth Confession (1968) and New York Tendaberry (1969), and had commercial success with artists such as Barbra Streisand and The 5th Dimension recording her songs.
By 1976, her marriage had ended, and she released an album of new material, Smile. She then embarked on a four-month tour with a full band, which resulted in the 1977 live album Season of Lights.  After the 1978 album Nested, recorded when she was pregnant with her only child, she again took a break from recording, this time until 1984's Mother's Spiritual. She began touring with a band in 1988, her first concert appearances in 10 years. The tour was dedicated to the animal rights movement. The shows led to her 1989 release, Laura: Live at the Bottom Line, which included six new compositions.  Her final album of predominantly original material, Walk the Dog and Light the Light (1993), her last album for Columbia, was co-produced by Gary Katz, best known for his work with Steely Dan. The release sparked reappraisal of her place in popular music, and new commercial offers began appearing. She turned down lucrative film-composing offers, although she contributed a rare protest song to the Academy Award-winning documentary Broken Rainbow, about the unjust relocation of the Navajo people.  Nyro performed increasingly in the 1980s and 1990s with female musicians, including her friend Nydia "Liberty" Mata, a drummer, and several others from the lesbian-feminist women's music subculture, such as members of the band Isis. During this period, Nyro made appearances at such venues as the 1989 Michigan Womyn's Music Festival and the 1989 Newport Folk Festival, of which a CD containing portions of her performance was released. On July 4, 1991, she opened for Bob Dylan at the Tanglewood Music Center in Lenox, Massachusetts. Among her last performances were at Union Chapel, Islington, London, England in November 1994; The New York Bottom Line Christmas Eve Show in 1994; and at McCabe's in Los Angeles February 11 and 12, 1995.  Both The Tonight Show and the Late Show with David Letterman staffs heavily pursued Nyro for a TV appearance during this period, yet she turned them down as well, citing her discomfort with appearing on television (she made only a handful of early TV appearances and one fleeting moment on VH-1 performing the title song from Broken Rainbow on Earth Day in 1990). According to producer Gary Katz, she also turned down a request to be the musical guest on the fall 1993 season opener of Saturday Night Live. She never released an official video, although there was talk of filming some The Bottom Line appearances in the 1990s.
Did she face any criticism in her later career?
