Question: Egbert B. Gebstadter is a fictional author who appears in the indexes of books written by an American professor who was born in what year?
Context: Janetta Walters is a fictional author of romantic novels, created by D. E. Stevenson.  Born Jane Watt, about 1913, she and her sister Helen lived in a small house in Bayswater in semi-genteel poverty, until she discovered her writing talent.  When her first romance, "Bride of May", was published by Abbott and Spicer, the two sisters could at last enjoy a life of comfort, with Jane writing and Helen acting as agent, housekeeper and amanuensis.  Her subsequent books include "Her Loving Heart", "Her Prince at Last" and "Love Triumphant". Professor Branestawm is a series of thirteen books written by the English author Norman Hunter.  Written over a 50-year period, between 1933 and 1983, the children's books feature as protagonist the eponymous inventor, Professor Theophilus Branestawm, who is depicted throughout the books as the archetypal absent-minded professor.  The name "Branestawm" is a pun, as a homophone of the word "brainstorm". Stanton Arnold Glantz, Ph.D. (born 1946) is an American professor, author, and leading tobacco control activist.  Glantz is Professor of Medicine in the Division of Cardiology, the American Legacy Foundation Distinguished Professor of Tobacco Control, and director of the Center for Tobacco Control Research and Education at the University of California, San Francisco (UCSF) School of Medicine.  Glantz's research focuses on the health effects of tobacco smoking.  Often called the "Ralph Nader of the anti-tobacco movement," Glantz is an activist for nonsmokers' rights and an advocate of public health policies to reduce smoking.  He is the author of four books, including "The Cigarette Papers" and "Primer of Biostatistics".  Glantz is also a member of the UC San Francisco Cardiovascular Research Institute and Institute for Health Policy Studies and co-leader of the UCSF Comprehensive Cancer Center Tobacco Program.  He was elected to the Institute of Medicine in 2005. Harvey Aronson (born May 1929) is an American journalist and journalism teacher, and a former "Newsday" editor who also wrote or co-wrote several books.  He was part of a group of "Newsday" reporters involved in writing the bestselling hoax novel "Naked Came the Stranger", initially credited to fictional author Penelope Ashe, and published as a parody of commercialized book publishing in general and of novels in the genre of Jacqueline Susann's "Valley of the Dolls" in particular.  Aronson co-edited the project with his colleague, Mike McGrady, who had conceived the idea, and Aronson also wrote a chapter of the book about a character described in a later news article as "Melvin Corby, a meek real-estate lawyer, unsatisfied in his marriage yet incapable of adultery, the only character in the book thus afflicted."  In a "Life" magazine article written after the ruse was revealed, Aronson commented that he thought the book had ended up being more comedic than pornographic, and he opined that Susann "writes about sex as if she were a virgin".
