Question: Did Richard Wilbur:or Robert Jordan used more pen names?

<P0-S0> James Oliver Rigney Jr. (October 17, 1948 – September 16, 2007), better known by his pen name Robert Jordan, was an American author of epic fantasy. <P0-S1>  He is best known for the "Wheel of Time" series, which comprises 14 books and a prequel novel. <P0-S2>  He is one of several writers to have written original Conan the Barbarian novels; his are highly acclaimed to this day. <P0-S3>  Rigney also wrote historical fiction under his pseudonym Reagan O'Neal, a western as Jackson O'Reilly, and dance criticism as Chang Lung. <P0-S4>  Additionally, he ghostwrote an "international thriller" that is still believed to have been written by someone else. <SEP> <P1-S0> Richard Purdy Wilbur (born March 1, 1921) is an American poet and literary translator. <P1-S1>  He is considered by many to be one of the greatest of the 20th century. <P1-S2>  Working primarily in traditional forms, his work is marked by its wit, charm, and gentlemanly elegance. <P1-S3>  Wilbur was appointed the second Poet Laureate Consultant in Poetry to the Library of Congress in 1987, and twice received the Pulitzer Prize for Poetry, in 1957 and again in 1989. <SEP> <P2-S0> Marijane Meaker (born May 27, 1927) is an American novelist and short story writer in several genres using different pen names. <P2-S1>  From 1952 to 1969 she wrote twenty mystery and crime novels as Vin Packer, including "Spring Fire", which is credited with launching the genre of lesbian pulp fiction (although few of Packer's books address homosexuality or feature gay characters). <P2-S2>  Using her own observations of lesbians in the 1950s and 1960s, she wrote a series of nonfiction books about lesbians under the pen name Ann Aldrich from 1955 to 1972. <P2-S3>  In 1972 she switched genres and pen names once more to begin writing for young adults, and became quite successful as M.E. Kerr, producing over 20 novels and winning multiple awards including the American Library Association's lifetime award for young-adult literature, the ALA Margaret Edwards Award. <P2-S4>  She was described by "The New York Times Book Review" as "one of the grand masters of young adult fiction." <P2-S5>  As Mary James, she has written four books for younger children. <SEP> <P3-S0> Wandering Stars is an anthology of Jewish fantasy and science fiction, edited by American writer Jack Dann, originally published by Harper & Row in 1974. <P3-S1>  It represented, according to the book cover, "the first time in science fiction that the Jew - and the richness of his themes and particular points of view -- will appear without a mask." <P3-S2>  In his introduction, "Why Me?" <P3-S3> , Isaac Asimov discussed how many Jewish science fiction writers prior to that time had used gentile pen names in order to get published: "Many of the Jewish pulp writers, however, used pen names as a matter of sound business. <P3-S4>  A story entitled "War Gods of the Oyster-Men of Deneb" did not carry conviction if it was written by someone named Chaim Itzkowitz." <P3-S5>  He then goes on to discuss the pen names of various Jewish writers included in this book. <P3-S6>  "Wandering Stars" is therefore of historical significance as the first science fiction anthology where Jewish writers openly identified themselves as such. <P3-S7>  It was followed by a second anthology, "More Wandering Stars", also edited by Jack Dann, published by Doubleday in 1981.
