Dr Karl Busch, co-founder of the Busch Group and a pioneer of modern vacuum pump technology, has died at the age of 96.
Busch co-founded the business with his wife Ayhan in 1963. What began with 5,000 Deutsche Mark grew into one of the world’s largest manufacturers of vacuum pumps, vacuum systems, blowers, compressors and gas abatement systems.
Today, the group operates in 44 countries, employs more than 8,000 people, and generates annual revenues of over $2 billion. Its technologies are widely used in sectors, including food and plastics packaging.
Born in Lörrach, Baden-Württemberg, in 1929, Busch studied mechanical engineering at the Technical University of Munich. He completed his doctorate in 1960, focusing on friction and wear in water-lubricated rotary compressors.
He went on to develop groundbreaking vacuum technologies, including the Huckepack and R5 vacuum pumps. The R5 model in particular became a standard in the packaging sector and remains one of the most commercially successful vacuum pump designs ever produced.
Busch was known not only for technical innovation but for his commitment to practical engineering and product reliability.
Family teamwork
He remained active in the company well into his 90s, taking part in meetings and business travel. He attended the group’s managers’ meeting in the Netherlands earlier this year, and just two months ago celebrated his 96th birthday with his family in Italy.
“Yet, beyond his business legacy, Dr Busch was devoted to his family,” a Busch Group spokesperson said. “Dr Karl and Ayhan Busch always worked together as a team of equals: as husband and wife for 62 years, parents, and business leaders. He was a father who truly listened with patience, curiosity, and trust and involved his children early in the company, sought their advice, and built a business culture rooted in family teamwork and shared purpose.”
A lifelong adventurer, Busch cycled from Maulburg to Istanbul, climbed Mount Kilimanjaro, and travelled around the world in 80 days in a vintage Mercedes alongside his sons. At 87, he completed a half marathon. He often repeated his personal motto, taken from the Alemannic dialect of his home region: “Never give up.”
The spokesperson added: “Dr Busch’s legacy will continue to live on, in the company he built, in the innovations he inspired, our company culture and values, and most of all, in the people whose lives he touched.”
