In addition to making an online searchable database of time travel literature, some of which falls under AH (
http://www.TimeTravelLit.com), I make a specialty of collecting and researching the works of Edward Stratemeyer (1862-1930) and His Stratemeyer Syndicate (1905-1985).
I spotted this question on Sunday morning with a Google News alert for Stratemeyer and indeed I have thought about this question before in some detail.
Edward was an amateur writer and printer in the mid 1870s while he was still in school. Despite this, his father, some 46 years older than he, was doubtful that Edward could make a career from writing. Ten years after his graduation from high school Edward was 26 and his father was 72 in the early months of 1889 when he made his first professional sale of a long serial to
Golden Days, a Philadelphia weekly story paper that was established by James Elverson in 1880. The $75 he received impressed his father and he stated to his son that if they were going to pay that for writing a story, he should write a lot more for them. Stratemeyer wrote several more stories for this periodical and others and then eased into book publications (beginning with reprints of his serials) in 1894. In 1898 he started to write specifically for book publication.
Stratemeyer tried to buy back the book rights for this first long (20,000 words) serial story, "Victor Horton's Idea," as well as the others he wrote for
Golden Days but Elverson would not sell them back even after the publication folded. After Elverson died, his son wouldn't sell the stories either. Hence, Stratemeyer was never able to reuse this material in other story papers or in book form as they were or updated as he had with the works that appeared elsewhere.
This is one of the reasons why I decided to publish Victor Horton's Idea as an annotated illustrated book on Lulu, something Stratemeyer could not do himself.
Even without the Syndicate, Stratemeyer's writing career was extensive and influential. About 160 of his personally-written stories were published as books. The most successful of these series was the
Rover Boys (1899-1926) as by "Arthur M. Winfield." By 1934 more than 5 million copies of these books had been sold. These were best sellers for that period.
The original post mentions that Stratemeyer usually wrote the first volume in each of the series. This is an old myth. He did so in only two occasions. He wrote the first
Bobbsey Twins book for publication in 1904. In 1907 the second title was published as a Syndicate production. He also wrote a serial story that became the first
Dave Fearless story. Later volumes were Syndicate productions where ghostwriters worked from his outlines. He maintained complete control and ownership of the stories, series, pseudonym and characters. The hired writers were paid promptly a sum equivalent to two months' wages as a newspaper reporter, their most common "day job", for their four-weeks of "moonlighting."
What is true is that the publishers with whom Stratemeyer worked wanted more and more material. It was greater than he could write on his own. The Syndicate was the natural outgrowth of this. The idea was used before (Dumas) and since then (Tom Clancy, Clive Cussler, etc.).
Where Edward wrote 160 stories published as books (and many more for periodicals), his Syndicate produced about 1,400 books between 1905 and 1985. These included some popular and influential books such as
Tom Swift,
Bomba the Jungle Boy, the
Hardy Boys, and
Nancy Drew.
The original question concerned what sort of changes we might see in a world where Edward Stratemeyer remained a clerk in one of the family tobacco stores. He did briefly run a stationery store in Newark in the first half of 1890 but he did not write "Victor Horton's Idea" there. It was written at home in 1888. Other stories were written in his brother's (Maurice's) tobacco and music store or his own store for the brief period when he had it. In November 1914 he opened an office in Manhattan off Madison Square Park so he could be closer to the offices of most of the publishers who handled his books.
The 19th century world of juvenile literature was dominated by authors like "Harry Castlemon," Horatio Alger Jr. and "Oliver Optic" in the U.S. and G.A. Henty, W.H.G. Kingston, and Mayne Reid in the U.K. Although the Alger and "Optic" (William T. Adams) books were sometimes grouped into publisher series, they did not have continuing characters in the way we think of series books today. There were some examples such as the Frank series by "Castlemon" (Charles A. Fosdick) and the Elsie Dinsmore series by "Martha Finley" (Martha Farquharson) but these were exceptions. Stratemeyer was among the early writers to popularize the use of a group of characters or a single character so that story after story could be told about them so long as the demand required more.
One of the main areas of influence from Syndicate books was in the form of other writers who read the series as youths and went on to write other things. For example, authors like Isaac Asimov, Ray Bradbury, Robert A. Heinlein, and Clive Cussler read the
Tom Swift series and were inspired to write fantastic stories as a result. Indeed, the existence of semi-realistic science fiction stories such as the
Tom Swift series (1910-1941) and the Verne-like
Great Marvel series (1906-1935) for young people created a large market for the first pulp sci fi magazines from Hugo Gernsback such as
Amazing Stories in a way that few others would have done.
An explicit goal of the
Tom Swift series about a young inventor was to inspire the readers to enter into careers that embraced engineering and aviation. There are many people who read the more than 6 million copies sold by 1934 who did just that. The series was popular enough that it was revived in the form of a
Tom Swift Jr. series (1954-1971) of 33 volumes which was even more successful since it was available for the Baby Boom Generation. Readers of these books who cite
Tom Swift Jr. as being influential into their career choices include people like Steve Wozniak and Bill Gates. Numerous astronauts and NASA workers have also named
Tom Swift (of either generation) as influential. Chuck Yeager was a youthful reader of
Tom Swift.
There is also the well-known story of the TASER being named for
Tom Swift and His Electric Rifle (1911) even though the design is actually based on an underwater electric gun from a
Great Marvel volume,
Under the Ocean to the South Pole (1907).
In other classes of literature, reread
To Kill a Mockingbird and notice the influence of the
Seckatary Hawkins books (by Robert F. Schulkers, not the Syndicate), the
Rover Boys, and
Tom Swift on the childhoods of the characters. Harper Lee has stated her appreciation for these books. Joseph Heller (
Catch 22) also mentioned
Tom Swift as an inspiration. Many examples can be found. George Lucas and Steven Spielberg have also been influenced by Stratemeyer series, especially
Tom Swift.
Nancy Drew has been a role model for independent young women. The current Secretary of State and the women on the U.S. Supreme Court name
Nancy Drew as a major influence on them. The list of prominent people inspired by this character is a long one.
In addition to the readers, there are other writers who worked for Stratemeyer at one time or another and they went on to write other things which have been enjoyed. The Syndicate often hired young writers with relatively little publishing experience and over the years of working with the Syndicate, their technique improved. Upon Edward Stratemeyer's death in May 1930, several of his writers thanked the family for the apprenticeship and guidance he offered to them.
The Stratemeyer Syndicate series included many successes (and some failures too) and their success inspired competitors in the form of other writers and publishers to issue similar material. So even if one thinks that
Judy Bolton (by Margaret Sutton),
Rick Brant (mostly by Hal Goodwin), or
Ken Holt (by Sam & Beryl Epstein) are better than their Syndicate counterparts, the fact that publishers like Grosset & Dunlap were even issuing books of this type was due to Stratemeyer starting to work with them in 1908 and the success they obtained with them.
Not only would childhood reading have been affected, but key people who were inspired by reading these books might have done things differently and perhaps not entered the fields for which they are now famous.
