from Wikipedia, the free encyclopedia

Claus Wellenreuther (* 1935 in Mannheim ) is a German entrepreneur and co-founder of SAP SE .

Life

Wellenreuther studied at the University of Mannheim , the specialist business administration with an emphasis on operations research .

He submitted his dissertation on Markoff processes and their application to waiting systems on July 8, 1968 at Walter Georg Waffenschmidt . After that, Wellenreuther worked for IBM in Mannheim . There he was involved in the development of financial accounting systems. At the end of 1971, however, he left IBM to program a standard financial accounting with batch processing . Shortly afterwards he joined his former IBM colleagues Hasso Plattner , Dietmar Hopp , Hans-Werner Hector and Klaus Tschira , who had also left IBM at the beginning of 1972 to develop standard software for real-time processing. Together the five founded the software company System Analysis and Program Development in Weinheim , which became SAP AG in 1988. Wellenreuther was particularly responsible for the architecture and the concept of the financial accounting module of SAP R / 2 .

Wellenreuther left the company in 1980 for health reasons. He received one million DM as a severance payment .

In 1982 he founded the company DCW Software (Dr. Claus Wellenreuther GmbH & Co. KG), which he expanded into a specialist for medium-sized ERP software. In 2003 the company was taken over by SAP. The takeover, known as a "deal among friends", annoyed many DCW customers who had consciously decided on an alternative to SAP software. In 2004 the company was merged with Steeb Application Systems GmbH .
