How the famous Geistlich adhesive “Konstruvit” found its way into almost every Swiss household, why fertiliser producers were so fond of travelling to Valais, and what adventures the young Andreas Geistlich experienced on the company premises – these and many other fascinating stories were shared by Martin and Andreas Geistlich at the opening event of the anniversary year.
The reading from the anniversary book took place on 3 February 2026 at the Wagi Museum in Schlieren, the home base of Geistlich Holding AG, marking the official kick-off of the anniversary year. The book was presented to the public for the first time in an intimate setting attended by representatives from local politics and business in Schlieren, as well as members of the Geistlich family.
Surprising insights
The book’s lead author, historian Colin Bätschmann, offered engaging insights into both the content and the creation of the anniversary book in four thematic sections. Personal anecdotes, historical context and surprising details brought the company’s history vividly to life.
The event was confidently hosted by Daniela Lager. Her moderation clearly demonstrated the depth of her engagement with the company’s history and contributed significantly to the warm and engaging atmosphere. The event provided a dignified and fitting setting for the start of the anniversary year and sparked anticipation for the highlights to come.
