1829-1833
Charles Wheatstone patents and builds the first English-system concertina, a six-sided instrument with each button playing the same note in both directions.
1834
Carl Friedrich Uhlig advertises the first German-system concertina, which he called a “20 töniges Accordion” [Chambers], with one or two rows of buttons and each button playing different notes on push and pull. This instrument, probably rectangular in shape, was the ancestor of the Anglo concertina, the bandoneon, and Chemnitzer and Carlsfelder concertinas.
1840s forward
Other makers of German concertinas appear in Germany. Other makers of English concertinas appear in England.
Around 1850
English makers, probably starting with Nickolds, make the first “Anglo-German” concertinas, combining English construction and hexagonal shape with German note layout. German makers begin making six-sided concertinas, primarily for export to England. These English and German concertinas are often similar to each other in keyboard layout and external appearance but are very different in internal construction.
1850s forward
English makers, possibly starting with George Jones, add a third row of buttons to the Anglo-German concertina to make the instrument more chromatic. Jones continues making concertinas until around 1905.
Date?
German makers make larger and larger square concertinas with more and more buttons in several layouts, eventually known as Bandonions, Chemnitzer concertinas and Carlsfelder concertinas. Bandonions eventually become the key instrument for Tango music in Argentina; Chemnitzers become popular with musicians of Eastern European descent in the Great Lakes area of the U.S.
Late 1850s
Wheatstone makes the rectangular 24-key “duett” or “double” concertina. This is the first duet-type concertina, with each button playing the same note in both directions and with a design intended to facilitate melody played on the right hand and accompaniment on the left.
1858
Former Wheatstone employee Louis Lachenal begins manufacturing concertinas at his own firm. The Lachenal firm goes on to make many concertinas (perhaps more than any other British maker) until 1933 when it was absorbed by Wheatstone.
1860s?
John Crabb begins to manufacture concertinas. His descendants continue the Crabb firm until 1989.
Early 1870s?
Charles Jeffries sells his first instruments under the Jeffries name, though they may have been partly or completely made by (initially) Jones or (later) Crabb until possibly as late as the early 1890s. Jeffries, followed by his sons, make concertinas until about 1930.
1884
John Hill Maccann patents his duet concertina, expanding Wheatstone’s prior “duett” system to make it fully chromatic. Maccann system instruments manufactured by Lachenal and later by Wheatstone, too.
1896
John Butterworth patents what becomes known as the Crane or Triumph duet system, manufactured by Lachenal (initially for Crane & Sons Ltd.) and later by Wheatstone and Crabb, too.
1949-1952
Marcello Bastari begins making inexpensive concertinas in Italy. Production continues to the present day (successor names of Bastari’s production are Stagi, Brunner and Concertine Italia).
