Actually, the modern missionary movements were almost all postmil at their inception.
I was referring specifically to the surge in missionary activity, with the formation of Missions such as the China Inland Mission, TEAM, Sudan Interior Mission.
J. Hudson Taylor of CIM, and Frederick Fransen of TEAM (then known as the Scandinavian Alliance Mission), and a group of young men of the day were all affected by the idea that at "any moment" Christ could come and they felt the urgency to evangelize as much of the world as possible.
Those who didn't promote missions began their careers as Evangelists, Dwight Moody among them, although he may have been a little late, or reluctant coming to embrace it fully, or ambivalent about Pre- or Post-.
Still at work, so I might be a little disjointed in reply.
