In 1898, he entered the army and served during the Spanish-American war, although he did not see combat.
In 1900, he returned to Chicago, where he went to work as an advertising salesman and writer.
It was well received and Anderson was considered one of the most important writers of his time.
Unfortunately, he was never able to replicate its success with other books.
However, he was a mentor to important American writers such as William Faulkner and Ernest Hemingway at the start of their own careers, so his impact on American literature has been long-lasting.
Anderson would continue to write throughout his life.
He went into business for himself in Elyria, Ohio, and started a family with Cornelia.
However, he was clearly still harboring literary aspirations, as he wrote four books during this time. Upon recovery, he left his business and his family and moved to Chicago.
In 1904, he married the first of his four wives, Cornelia.
For the next eight years, he was a model businessman and family man.
