Walter Lionel George (20 March 1882, Paris, France – 30 January 1926) was an English writer, chiefly known for his popular fiction, which included feminist, pacifist, and pro-labour themes.

In addition to novels and short stories, George also wrote literary essays and several political tracts on left-wing themes.

[3] According to Alec Waugh, he was commercially successful, helpful in practical terms to upcoming authors, but unpopular in the literary world for his subject matter, his hack journalism, and his left-wing views.

[7] Washington Post columnist John Kelly opined in 2022 that, although George had been unduly optimistic and gotten some details wrong, he "had gotten nearly all of it right", noting George's predictions of an eight-hour flight time between New York and London, decreased reliance on fossil fuels, the availability of legal birth control, motion pictures with sound and color, the displacement of freight railroads by an emerging trucking industry, and wireless telephones.

The Pall Mall Gazette of 19 July 1909 printed a letter from George correcting various mistakes but the actual title of the book was not mentioned in the article.
