G. A. Henty
Henty wrote 122 works of historical fiction and all first editions had the date printed at the foot of the title page. (Reference G.A.Henty 1832-1902 A Bibliographical Study by Peter Newbolt.) Several short stories published in book form are included in this total, with the stories taken from previously published full length novels.
Henty once related in an interview how his storytelling skills grew out of tales told after dinner to his children. He wrote his first children's book, Out on the Pampas in 1868, naming the book's main characters after his children. The book was published by Griffith and Farran in November 1870 with a title page date of 1871. While most of the 122 books he wrote were for children, he also wrote adult novels, non-fiction such as The March to Magdala and Those Other Animals, short stories for the likes of The Boy's Own Paper and edited the Union Jack, a weekly boy's magazine.
