Company history 

The birth of today's SICK AG: Erwin Sick receives a license from the American military government in Munich for his own engineering office.

Presentation of the first marketable accident prevention light curtain at the International Machine Tool Trade Fair in Hanover. The resultant orders led to the initial serial production and was the economic breakthrough.

The company, with 25 employees, moves to Waldkirch.

The first subsidiary is founded in France.

Expansion overseas with the founding of a subsidiary in the USA.

Erwin Sick dies at the age of 79. Gisela Sick runs her husband's company as the chief partner.

Conversion of Erwin Sick GmbH (a kind of private limited company) to an Aktiengesellschaft (joint stock company).

The first issue of employee shares domestically and abroad.
