Gotthilf Lufft founded the firm Mech Werkstatt G Lufft in Stuttgart, Germany in 1881, and was the pre-eminent German manufacturer of barometers and barographs. Lufft, a name that rapidly gained worldwide recognition for excellence, supplied the majority of such instruments to the German government and armed forces during both World Wars. 

Interestingly, the first barocyclonometers (the enhanced Faura typhoon barometers) designed by Father José Algué, S. J., director of the Philippine Weather bureau, Manila observatory, were commissioned by him from Lufft in the early 1900s, ahead of the, by then much respected, French and British makers, because of the consistent excellence of Lufft’s production.

This table barometer is a very unusual model, and certainly represents amongst the very best in continental aneroid barometer making.
