With the help of his teacher, he managed to obtain a mechanical apprenticeship with Friedrich Heller, Nuremberg's oldest electric company.

In the meantime he pursued his hobby, telegraphy, at the same time, through self-study, deepening his knowledge of arithmetic, geometry, physics and chemistry.

Essentially, he was keen to meet the best professionals of the top companies, to expand his knowledge and to gain insights from those with whom he worked, while developing his own ideas.

While he was working in the electrical department of the Optical equipment business headed up by Albert Krage, Sigmund Schuckert learned English.

From New York he traveled via Baltimore, Philadelphia and Cincinnati, ending up in Newark, New Jersey, where he worked in the telegraph factory of Thomas Edison.

Resulting success in the marketplace, supported by the high-profile Linderhof contract, increased pressure to grow the business.

The larger premises made possible a big increase in production of arc lights, the quality of which would receive widespread recognition at the Paris World Fair in 1889.

In order to be able to meet customer demand, additional land was acquired and production capacity built in the Landgrabenstraße.

Nervous exhaustion forced Sigmund Schukert to retire from his business in 1892, and in 1895 he died at Wiesbaden which was at that time a spa town of international renown.

In the end he also set up the Sigmund Schuckert Foundation with the objective of supporting deserving schoolchildren and students.
