Who were the Futurians? They were an amazing group of fans and writers who gathered between 1935 until 1945. On the left we see a some of the founding members: Frederik Pohl, John Michel, and Donald A. Wollheim.
The entire membership can be found here, but includes many who went on to have influential careers in Science Fiction. Wollheim, seen in the picture, organized the first science fiction convention on October 22, 1936 in Philadelphia, which later transformed into what we now call Worldcon.
What would Science Fiction have become without them? It’s hard to say, but certainly the genre we know and love was forever changed by their vision and writing.
