Jonas Lidströmer

Jonas Lidströmer has often been called Sweden's "mechanical genius" and is occasionally compared with Christopher Polhem, another notable Swedish inventor.

He also collaborated with the artists Johan Tobias Sergel, Louis Jean Desprez and Ehrensvärd, and a letter correspondence with Carl Christopher Gjörwell has been preserved.

He is credited with a number of mechanical devices and innovations, such as a horse-drawn grinding machine and lathe, new methods of moulding, and compasses.

His younger surviving son, Johan Nikolaus Lidströmer, who inherited the Allatorp property outside Karlskrona in Blekinge, had children, but no grandchildren.

The younger son, Fredrik Lidströmer, who was an officer in the former Swedish colony of Saint Barthélemy in the Caribbean did, however, not have any children.
