It was a companion to Future Science Fiction, and like that magazine was edited by Robert W. Lowndes and published by Columbia Publications.
Stories that appeared in its pages include "The Duplicated Man" by Lowndes and James Blish, and "The Possessed" by Arthur C. Clarke.
It was launched at the end of the pulp era, and when publisher Louis Silberkleit converted Future to a digest format in 1954, he decided not to do the same with Dynamic, simply cancelling the magazine.
All three had ceased publication by the end of World War II, killed by a combination of falling sales and wartime paper shortages.
[2] Robert W. Lowndes was the editor of all six issues of Dynamic Science Fiction, which remained in pulp format throughout its run.
