Anton Große-Wentrup founded the company on the 1st October 1941 as a firm specialized for industrial plants in the mining industry. For many years the AGW, named after its founder, was a traditional small-scale business, until Dipl.-Ing. Clemens Recker and Hans-Jürgen Manke took over the management in the year 1992.

Ever since, the business has been developed to an aspiring middle-scale company, which has great national and international experience.

The company name was changed into the Anton Große-Wentrup GmbH (cf. Limited Company). Since the 1st January 1993 the AGW has got an official teaching programme and employs numerous apprentices. Over the years, the range of services has been extended, especially in the area of automation technology and instrumentation and control engineering.

In the year 1997 we moved into a new company building with a new factory (Schäferstraße 39a). Presently, about thirty five employed persons support and realize our projects within and outside the European Union.

Since 28th November 1996 the AGW has got an approved and effective quality management system—the certification DIN EN ISO 9001 was granted by the Germanische Lloyd Certification GmbH (today DNV GL), and it covers the application areas planning, development, design and construction of electrical systems in the fields of power engineering, automation technology, and instrumentation and control engineering. The certification of the Environment and Employment Protection Management System SCC** took place in 2010.

In 2018 Michael Manke took over the responsibilities and activities of his father Hans-Jürgen Manke.
