Claus Wisser was a prominent German businessman known not only for his entrepreneurial success but also for his significant contributions to the world of arts, culture, and charitable endeavors. Let’s delve into the life and achievements of Claus Wisser.

Early Life and Education

Claus Wisser was born on June 30, 1942, in Wiesbaden, Germany, into a family of shopkeepers. He attended the Friedrich List School and began helping in the family shop from a young age. Despite the early responsibilities, he showed remarkable dedication to education and public engagement.

While still in school, Wisser joined the Social Democratic Party (SPD), demonstrating his early commitment to political involvement. He pursued higher education in business administration at the University of Frankfurt. During his university years, he actively participated in the student protests against the German Emergency Acts and attended public lectures by notable figures like Carlo Schmid.

Entrepreneurial Journey

In 1965, at the age of 23, Claus Wisser embarked on his entrepreneurial journey by founding a company specializing in the cleaning of office buildings. At the outset, he famously advertised for a used typewriter as a gift. With determination and hard work, he began the business as its sole worker, armed with a broom, bucket, and the typewriter.

Under his leadership, the company expanded into what is now known as Wisag, a conglomerate offering services such as cleaning, park maintenance, security, and catering, among others. Wisag grew to employ an impressive 50,000 employees. Claus Wisser’s dedication and vision played a pivotal role in this transformation.

While Wisser initially ventured into textiles, which proved unsuccessful and left him with significant debts, he quickly redirected his focus towards service industries. These included services for industry, administration, airlines, and airports, particularly ground traffic management for airports.

During the 1990s, Claus Wisser began transitioning away from day-to-day operational roles within Wisag. He entrusted the company’s operations to professionals, including his son Michael Wisser, who later became the chairman of the company in 2007. Claus Wisser assumed the role of chairman of the supervisory board, and in 2022, he was honored with the title of honorary chairman of the supervisory board.
