Our history

129 years’ experience in microbiology

In 1889, Schülke & Mayr founders Rudolf Schülke and Julius Mayr launched Lysol®, the first brand-name disinfectant. In 1892, it was employed to successfully control a cholera epidemic raging in Hamburg. 

The microbiological science initially used to protect people was soon applied to safeguard industrial products – beginning with the introduction of grotan®, the world’s first brand-name preservative, in 1924. Today, over 100 years after schülke was founded, innovation remains an essential part of our company’s philosophy. Over 200 patents, certificates, and awards are testimony to our trailblazing  approach. 

Since 1996, schülke has been part of Air Liquide, a global enterprise headquartered in France and specialising in the manufacture and distribution of industrial and medical gases.
