Americus Backers (died 1778), sometimes described as the father of the English grand pianoforte style, brought the hammer striking action for keyboard instruments from his master Gottfried Silbermann's workshop in Freiburg to England in the mid-18th century.
Since we know that Zumpe, next to set up shop in England, arrived in 1756, Americus must have been here before this, yet we have no record of his domicile or trade until 1763 when he took up residence in London's Jermyn Street (with the Anglicized Christian name of Andrew) where, according to the rate books of St. James, Piccadilly, he lived until 1778.
Subsequent Backers pianos were used by J.C. Bach and his protégé Johann Samuel Schroeter for concerto performances in London and would certainly have been known by Muzio Clementi.
We know from the history of the Broadwood family that John Broadwood and his fellow Scot Robert Stodart – both apprentices to the harpsichord builder Burkat Shudi (Anglicized) – would spend evenings at Americus's Jermyn Street home and workshop, helping him to perfect his escapement for his pianoforte action based on, but differing in several important factors, from Silbermann's design that was in turn developed from Cristofori's original.
(The term Grand Pianoforte for this design was not coined until Robert Stodart patented and used it to adorn the nameplate of a 1777 model bearing his name as manufacturer.)
The right hand pedal operated a mechanism that lifted all the dampers away from the strings, Americus's own original idea that was not copied by the Viennese piano makers until much later.
Following hot on the heels of the Backers instruments came offerings from John Broadwood, succeeding his master, and from Robert Stodart striking out in business on his own.

The Russell Collection, St. Cecilia's Hall (University of Edinburgh) There is a photograph of a copy built by Michael Cole in 1960 now in the Cantos Collection at [2] The instrument shows no evidence of alteration (it was quite common for piano buyers to have their instruments altered, for example to extend their compass with extra notes) The mahogany case with boxwood cross-banding encloses a wooden frame and soundboard with paper rose.
These properties, combined with the smoothness and responsiveness of the escapement, encourage the player to adopt a right hand style that majors on scales and ornamentation overlaying sustained bass notes and chords since the hammer action gives the tenor and bass register considerable power, duration and harmonic richness and complexity through each note - tones that cannot be achieved by the string plucking action of a harpsichord.
For example, Richard Rodney Bennett's book of simple modal pieces The Days of the Week, sounded well on the piano, giving the music the wistful and ethereal quality sought and marked by the composer.
(This optimum striking distance was discovered and standardized by the first John Broadwood before the end of the 18th Century indicating that he possessed an exceptional ear for identifying and eliciting the maximum musical appeal from his instruments bearing in mind that he had no knowledge of, or access to the applied physics and scientific measuring techniques that were more recently used to identify ideals of piano design for the modern era.)
judge that the surprising qualities of an early English grand pianoforte would have persuaded the 18th Century prospective keyboard instrument purchaser to buy it in preference to a traditional harpsichord and to use the new music written for it to show off its capabilities to envious house guests.
Although the piano is not especially loud at full power, it does show an impressive width of dynamic range compared to the plucked string instrument and it is fully capable of satisfying the original demand that Ferdinando di Medici made of Cristofori – to create an instrument that would, in accompanying his voice at home singing from the popular entertainments of the day mimic the gradual rising crescendo and falling diminuendo volume as well as the power to surprise an audience with the sudden 'snap' of a loud note or chord to contrast with a quieter preceding passage sforzando of an opera house light orchestra.
In the opinion of expert students of the works of Jane Austen, Pride and Prejudice showcases two brand new Americus Backers pianofortes - one purchased by Mr. Darcy for his sister and the other in the "fine modern house" of his aunt, Lady Catherine.
We are intended to envy and to admire her characters who were fashion leaders in the highest society whose new Palladian residences were commissioned with the sole purpose of impressing house guests, to which end they were filled with the very utmost in furnishings and fittings that London and the British Empire has to offer, including the novelty of a brand new class of musical instrument - the piano.
So a Backers piano is intended to imply the owner is at the cutting edge of fashion with the taste and disposable funds that make them the leaders and most enviable members of high society.
