Conduit 1, also known by its systematic name BFx59H, is one of the earliest and most remarkable converters, discovered by David Buckingham on July 5, 1996. Composed of a block and a snake (or eater 1 in either of two orientations to make it Spartan, or shillelagh for slightly better clearance[1]), it transforms a B-heptomino into a clean Herschel with very good clearance in 59 generations, allowing easy connections to other conduits.
It forms the final stage of many of the known composite conduits, including the majority of the original sixteen Herschel conduits. It is important because it was one of the key pieces in finding a method for construction of oscillators and guns of arbitrary large period (see omniperiodic).

Earlier in 1992, Buckingham found a collision involving two 180-degree gliders and the block in the exact relative position to snake that gives rise to the same Herschel. The reaction has a repeat time of 65 ticks. This is used by the over-unity reaction in a p500 glider gun built around November 17.[2]
