Precision since 1954

Our history

Tradition and motivation: How we have been moving the world for over six decades

In the 1950s, the world was particularly on the move. This also applied to Kenneth Slee, who founded the company during this time with his vision of unique high-precision devices. In 1954, he developed together with the pathologist Prof. Pearse the world’s first cryostat microtome – a milestone for Slee and the entire histopathology.

With the relocation to Mainz in 1963, Slee’s unique story of success started off in Germany. Slee has been a manufacturer of precision technology in the field of histopathology for almost 70 years, and for six decades, the Slee brand has stood for high-quality medical products “Made in Germany”.
