He didn't write any books in the literary sense. He was a travel agent, businessman, and social reformer.
His primary contribution was establishing the first organized tourist trips and founding the travel company that bears his name.
While he didn't write novels or poetry, he did publish:
* Travel guides and itineraries for his tours.
* Articles and pamphlets on topics like temperance and social reform.
* Letters and diaries documenting his travels and business ventures.
So, although he didn't write traditional books, his work significantly shaped the tourism industry and left a lasting legacy in the world of travel.
