Denis d'or

[1] The Czech theologian Václav Prokop Diviš, who had his parish in the Moravian town Přímětice near Znojmo, was interested in both music and electricity.

Some sources even date its existence as far back as the year 1730, but this claim is historically untenable and not supported by any available information on Diviš's biography and work.

[2] The Denis d'or was reported to have 14 registers, most of which were twofold, and its complex mechanism fitted in a symmetrical wooden cabinet equipped with a keyboard and a pedal.

This was mainly owing to the responsiveness and combinability of the stops, which permitted the player to vary the sound in multiple ways, thereby generating far more than a hundred different tonal voices altogether.

Allegedly, Diviš could charge the iron strings with electricity in order to enhance the sound quality.
