The swabian tinkerer and chemist Karl Buck invented the first WC-cleaning block and, aged 54, took the brave step of founding our company. His wife sold the first WC-cleaning blocks at her chemist’s store in Stuttgart. Buck-Chemie was set up in 1966 to begin industrial-scale production of the WC blocks. The company has grown steadily from that time onwards. Following Karl Buck’s death in 2010, the company was reorganised under the umbrella of Buck Group AG 2013, with a new forward-looking strategy.

Our History

Karl Buck

The origins of Buck Group date back to Karl Buck, who founded Buck-Chemie.

the creation of Buck-Chemie GbmH

Karl Buck was a chemical engineer who in his spare time developed various products for his wife, Anna Buck, who ran a pharmacy. During the 1950s, when the standard toilet-cleaning product was concentrated hydrochloric acid, he began researching a safer method of cleaning. The result: the predecessor of today’s WC cleaning block – a product to be hung in the toilet, distributing cleansing power with each flush. It was registered with the German patent and trade mark office in 1965 as “WC-66”. This laid the foundation for Buck-Chemie GmbH, which Karl Buck founded in 1966. He worked at the company for the rest of his life.

about Karl Buck

Karl Buck was born on July 24th, 1912 in Stuttgart-Feuerbach. His life was shaped mainly by his experiences in the period after WWI, as well as his time as a soldier and as a prisoner of war during the second world war. Buck was a trained lab technician and chemical engineer.

Karl Buck was actively involved in shaping the company’s fortunes right up until his death on October 16th, 2010 at the age of 98.
