Anatole Mallet
Jules T. Anatole Mallet (23 May 1837 – 10 October 1919) was a Swiss mechanical engineer, who was the inventor of the first successful compound system for a railway steam locomotive, patented in 1874. 
He is known for having invented three important forms of compound locomotive.
In 1876 he introduced a series of small two-cylinder compound 0-4-2T tank locomotives for the Bayonne-Anglet-Biarritz Railway in France.
He subsequently designed an articulated compound system with a rigid chassis
Divided drive (locomotive)
A divided drive locomotive is a steam locomotive that divides the driving force on its wheels by using different cylinders to power different pairs of driving wheels in order to give better weight distribution and reduce "hammer blow" which can be damaging to the track, or else to enable the wider spacing of the driving wheels to accommodate a larger firebox.
