David Loeschman was a remarkable character. Apart from this one, only one other piano carrying his name is recorded, a cabinet piano last heard of in Den Haag.
But perhaps he should be better remembered as an inventor. Musicians have wrestled with the problems of tuning and temperament for hundreds of years, and one obvious idea to distinguish between for example G sharp and A flat is to provide more than twelve keys in the octave. These are often called 'enharmonic' keyboards, and a number of historical examples exist. The nameboard of this instrument describes him as 'Inventor and Manufacturer of the Patent Enharmonic Grand...'
A summary of his 1809 patent, in his own words, is given below:
Sad to say (but perhaps not surprising) no example of an instrument using this patent is known, nor indeed any evidence that such a thing was ever built.
By contrast, the piano now offered is relatively conventional. The generously rounded corners, or 'circular ends' as they were called at the time, do perhaps remind us of Dettmer, but there is no sign of his usual 'GWD' mark on the soundboard.
The pedal is missing, but good to see the original silk-covered inner board.
Conventional English double action, and 'dolly' dampers.
This piano is generously offered Free to Good Home, but the owner would prefer that it should remain in the UK, with the intention that it should be carefully restored. It is currently in Leintwardine, Herefordshire, and as usual the new owner will be responsible for collection and transport.
