Question: What is the middle name of the English author whose bibliographer was Jon Gilbert?
Context: Thomas Troward (1847–1916) was an English author whose works influenced the New Thought Movement and mystic Christianity. Barend or (somewhat dated spelling) Barent is a Dutch male given name and occasional middle name.  As of 2014, there are over than 4,000 men in the Netherlands with this as their first name, and nearly 3,000 with it as their middle name.  It was likely derived from Bernard.  Notable people with the name include: In several cultures, people's names usually include one or more names in addition to the portion that is usually considered adequate to identify them.  In a number of cultures where a given name is expected to precede the surname, such a name is likely to be placed after the given name and before the surname, and thus called a middle name.  In English-speaking American culture, that term is often applied (arguably mistakenly) to names, occupying that position, even if the bearer would insist that that name is being mistakenly called a "middle name", and is actually (to mention several types of atypical cases): Ester Sowernam, English author whose pen name comes from Esther in the Old Testament, who defended her people against Haman.  Sowernam is also the antithesis of Joseph Swetnam’s last name (sweet/sour).  She was the second of three women to respond to Swetnam’s "The Arraignment of Women" in her pamphlet, "Ester Hath Hanged Haman"; or "An Answer to a Lewd Pamphlet, Entitled The Arraignment of Women" in response to "The Arraignment of Lewd, Idle, Froward and Unconstant Men, and Husbands" (1617). Eliza Fenwick (1 February 1766 – 8 December 1840) was an English author whose works include, "Secresy; or The Ruin on the Rock" (1795), as well as several children's books.  Born in Cornwall, she married an alcoholic and had two children with him.  She eventually left him to live with her children in Barbados, where she ran a school with her daughter. Jeff Strabone is a Brooklyn-based American scholar, political activist and civic leader.  In 2016, his website "directelection.org" listed the names and addresses of members of the U.S. Electoral College, and he urged people to write to electors to ask them not to vote for president-elect Donald Trump, an effort which brought him national attention.  As a civic leader in Brooklyn, he has been active in promoting theatre preservation, building codes and housing issues, hospital preservation, and traffic flow.  He has been a leader of Brooklyn's Cobble Hill Association, a neighborhood preservation group.  He is the co-founder and chairman of the New Brooklyn Theatre.  In 2008, he changed his middle name to "Hussein" as a show of solidarity with then presidential candidate Barack Obama, who was running for the office of president, and who had been criticized for his Muslim-sounding middle name.  He is an associate professor of English and teaches British and African literature, and he was granted tenure at Connecticut College in 2016.  He commented about the post-election effort: Ian Lancaster Fleming (28 May 1908 – 12 August 1964) was an English author, journalist and naval intelligence officer who is best known for his James Bond series of spy novels. Fleming came from a wealthy family connected to the merchant bank Robert Fleming & Co., and his father was the Member of Parliament for Henley from 1910 until his death on the Western Front in 1917.  Educated at Eton, Sandhurst and, briefly, the universities of Munich and Geneva, Fleming moved through several jobs before he started writing. William Simpson Potter (21 January 1805 – 16 January 1879) was a 19th-century English author.  From available information, Potter was a friend of Henry Spencer Ashbee, a merchant, bibliographer, bibliophile, authority on the life and works of Cervantes, and collector of erotic materials.  Ashbee describes Potter as a "shrewd business man, the ardent collector, and the enthusiastic traveller". Jon Gilbert is an English bibliophile, historian and the official bibliographer of Ian Fleming, creator of the fictional character James Bond.  He is also an authority on J.K. Rowling first editions.  He was educated at Caterham School and Roehampton Institute London. John Waynflete Carter (1905–1975) was an English author, diplomat, bibliographer, book-collector, antiquarian bookseller and Vice-President of the Bibliographical Society of London.  After attending Eton College, he studied classics at King's College, Cambridge, where he gained a double first.  His 1934 exposé, "An Enquiry into the Nature of Certain Nineteenth Century Pamphlets", co-written with Graham Pollard, exposed the forgeries of books and pamphlets by Harry Buxton Forman, a distinguished executive editor of Keats and Shelley, and Thomas J. Wise, one of the world's most prominent book collectors.  Forman and Wise's crimes are generally regarded as one of the most notorious literary scandals of the twentieth century.  Carter also wrote seminal books on aspects of book-collecting, and served on the board of directors of the influential journal The "Book Collector", published by Queen Anne Press, a company managed by James Bond creator Ian Fleming.  Carter also edited the prose of the poet A. E. Housman.  He was the husband of the writer and curator Ernestine Carter and the brother of the printer Will Carter (1912–2001) of the Rampant Lions Press, at which some of his smaller-scale works were published.  He was also a humorist and writer of clerihews, some of which were printed by Will Carter in 1938.
