Karl Moritz Immisch (born March 12, 1838 in Niederschmon near Querfurt , † September 20, 1903 in London ) was a German watchmaker , electrical engineer and inventor .

Life and work as inventors and entrepreneurs

Apprenticeship as a watchmaker

After completing technical training, Immisch went to London in 1860 , married Emma Elizabeth Welch in 1876 and earned his living repairing, improving and inventing technical equipment at Le Roy & Fils. He proved his technical skills in both the learned watchmaking trade and in the analysis and description of mechanical-technical processes, in which precision played an important role.

Patent for a compact thermometer

In 1881 Immisch received a patent and a silver medal for a compact thermometer in the form of a manometer with the use of a Bourdon tube as a measuring element. This design with the Bourdon tube, commonly called Bourdon tube after its inventor , was more robust than the usual mercury- filled glass thermometers. With his experiments on the electrotechnical principles he examined and understood the new possibilities of the electrotechnical manufactories in the making.

Patenting of a DC motor

In 1882 he submitted the patent for an improved DC motor and in the same year founded the company M. Immisch & Co with friends and colleagues for the industrial application of electric drives for pumps , cars , trams and ships .

With Magnus Volk as manager of Immisch & Co, railways and cars were equipped with electric drives and wooden boats were successfully built from 1887, which were equipped by Immisch & Co with electric drives, power storage and controls. Setting up a rental company based on the island of Platts Eyot also included the infrastructure on the Thames for charging the batteries . Immisch's propulsion systems, consisting of direct current motors with accumulators as power storage devices, more rarely with overhead lines like the Brighton and Rottingdean Seashore Electric Railway , were used just as successfully to drive trains from 1889 onwards. However, with the widespread introduction of overhead lines, they soon lost their importance.

End of life

Immisch was at Acme Immisch Electric Works Company Ltd. for several years. involved in the construction of e-cars , but his main interest in recent years has been his long-term companies that have been involved in the introduction of electric drive technology. He suffered increasingly from heart problems and in 1901 he retired from business. Karl Moritz Immisch died in London on September 20, 1903.
