Thrilling Wonder Stories

American science fiction magazine often abbreviated TWS, founded by Hugo Gernsback.

After losing control of Amazing Stories, Gernsback launched Air Wonder Stories and Science Wonder Stories in 1929 and merged the two magazines into Wonder Stories in 1930. He sold the prozine to another pulp house in 1936, and then it became Thrilling Wonder Stories, which lasted until 1955.

With this magazine, Gernsback created the Science Fiction League, the seminal sf club that led to the emergence of fandom.
