Back of the beating hammer
   By which the steel is wrought,
Back of the workshop’s clamor
   The seeking may find the thought;
The thought that is ever master
   Of iron and steam and steel,
That rises above the disaster
   And tramples it under heel!

The drudge may fret and tinker,
   Or labor with lusty blows,
But back of him stands the thinker,
   The clear-eyed man who knows;
For into each plow or sabre,
   Each piece and part and whole,
Must go the brains of labor
   Which gives the work a soul!

Back of the motor’s humming,
   Back of the belts that sing,
Back of the hammer’s drumming,
   Back of the cranes that swing,
There is the eye which scans them,
   Watching through stress and strain,
There is the mind which plans them—
  Back of the brawn, the brain!

Might of the roaring boiler,
   Force of the engine’s thrust,
Strength of the sweating toiler,
   Greatly in these we trust.
But back of them stands the schemer,
   The thinker who drives things through;
Back of the job—the dreamer,
   Who’s making the dream come true!

—Berton Braley (1882-1966)
