Isaac Asimov (; c. January 2, 1920 - April 6, 1992) was an American writer and professor of biochemistry at Boston University. He was known for his works of science fiction and popular science. Asimov was a prolific writer who wrote or edited more than 500 books and an estimated 90,000 letters and postcards. His books have been published in 9 of the 10 major categories of the Dewey Decimal Classification.
Asimov attended New York City public schools from age 5, including Boys High School in Brooklyn. Graduating at 15, he went on to Seth Low Junior College, a branch of Columbia University in Downtown Brooklyn designed to absorb some of the Jewish and Italian-American students who applied to Columbia College, then the institution's primary undergraduate school for men with quotas on the number of admissions from those ethnic groups. Originally a zoology major, Asimov switched to chemistry after his first semester as he disapproved of "dissecting an alley cat". After Seth Low Junior College closed in 1938, Asimov finished his BS degree at University Extension (later the Columbia University School of General Studies) in 1939.  After two rounds of rejections by medical schools, Asimov in 1939 applied to the graduate program in chemistry at Columbia; initially rejected and then accepted only on a probationary basis, he completed his Master of Arts degree in chemistry in 1941 and earned a Doctor of Philosophy degree in biochemistry in 1948.  In between earning these two degrees, he spent three years during World War II working as a civilian at the Philadelphia Navy Yard's Naval Air Experimental Station, living in the Walnut Hill section of West Philadelphia from 1942 to 1945. In September 1945, he was drafted into the U.S. Army; if he had not had his birth date corrected, he would have been officially 26 years old and ineligible. In 1946, a bureaucratic error caused his military allotment to be stopped, and he was removed from a task force days before it sailed to participate in Operation Crossroads nuclear weapons tests at Bikini Atoll. He served for almost nine months before receiving an honorable discharge on July 26, 1946. He had been promoted to corporal on July 11.  After completing his doctorate and a postdoc year, Asimov joined the faculty of the Boston University School of Medicine in 1949 with a $5,000 (equivalent to $51,427 in 2017) salary, with which he remained associated thereafter. By 1952, however, he was making more money as a writer than from the university. The difference grew, and in 1958 Asimov stopped teaching to become a full-time writer. Being tenured, he retained the title of associate professor (which he had held since 1955), and in 1979, the university honored his writing by promoting him to full professor of biochemistry. Asimov's personal papers from 1965 onward are archived at the university's Mugar Memorial Library, to which he donated them at the request of curator Howard Gotlieb.  In 1959, after a recommendation from Arthur Obermayer, Asimov's friend and a scientist on the U.S. missile protection project, Asimov was approached by DARPA to join Obermayer's team. Asimov declined on the grounds that his ability to write freely would be impaired should he receive classified information. However, he did submit a paper to DARPA titled "On Creativity" containing ideas on how government-based science projects could encourage team members to think more creatively.

Where else did he go to school?

After Seth Low Junior College closed in 1938, Asimov finished his BS degree at University Extension (later the Columbia University School of General Studies) in 1939.



Answer the question at the end by quoting:

"Hound Dog" is a twelve-bar blues song written by Jerry Leiber and Mike Stoller. Recorded originally by Willie Mae "Big Mama" Thornton on August 13, 1952, in Los Angeles and released by Peacock Records in late February 1953, "Hound Dog" was Thornton's only hit record, selling over 500,000 copies, spending 14 weeks in the R&B charts, including seven weeks at number one. Thornton's recording of "Hound Dog" is listed as one of the Rock and Roll Hall of Fame's "500 Songs That Shaped Rock and Roll", and was inducted into the Grammy Hall of Fame in February 2013. "Hound Dog" has been recorded more than 250 times. The best-known version is the July 1956 recording by Elvis Presley, which is ranked number 19 on Rolling Stone magazine's list of the 500 Greatest Songs of All Time; it is also one of the best-selling singles of all time.
Two records were released that were neither cover versions of nor answers to Thornton's release, yet used a similar melody without any attribution to Leiber and Stoller. The first was Smiley Lewis's "Play Girl", credited to D. Bartholomew and released by the Imperial Records label (Imperial 45-5234) by the end of March 1953. Described as a "stomping uptempo boogie rocker", it began: "You ain't nothin' but a Play Girl / Staying out all night long". In April 1955, female impersonator Jesse "Big 'Tiny'" Kennedy recorded "Country Boy" accompanied by His Orchestra that was released by RCA's Groove Records (Groove 4G-0106) by May 21. While credited solely to Kennedy, this song has a similar melody to "Hound Dog": "'Country Boy' has a deceptively slouching flip on the 'Hound Dog' motif - this time with Tiny proclaiming proudly that he 'ain't nothing but a country boy'".  In the early 1970s Robert Loers, owner of Dutch label Redita Records, found a song with the same melody as "Hound Dog" called "(You Ain't Nuttin' But a) Juicehead" on an anonymous acetate at Select-o-Hits, the Memphis distributorship owned by Sam Phillips' brother, Tom, where Sun artifacts were stored.  When Juice Head first appeared on a Redita Records LP [in 1974], it was credited to Rosco Gordon. But it's not Rosco. It simply is not him. Really. Even Rosco confirmed that. It might not even be a Memphis Recording Service demo. Just substitute the words "Hound Dog" for "Juice Head" and what have you got? Of course the inspiration for this song came from Big Mama Thornton's "Hound Dog" or perhaps even from Rufus Thomas' "Bear Cat". But the song's other parent is Eddie Vinson's slowed down "Juicehead Blues" which harks to the previous decade...If indeed this originated from Sam Phillips' studio, it was nothing that Phillips needed to touch because it was another lawsuit waiting to happen."  Philip H. Ennis sees "Two Hound Dogs", which was recorded on May 10, 1955, by Bill Haley & His Comets (Decca 29552), as a response to Thornton's recording. While not an answer record in the traditional sense, the lyric characterized "Rhythm" and "Blues" as the titular "Two Hound Dogs," an apparent testament to the stature of "Hound Dog."
