It was a well-known Swiss graphic designer and painter Hans Tomamichel. who designed the logo of Institut Montana back in 1947.
The design represents the connected world. It shows a young plant, supported by a stake that will ensure that it grows healthily towards the sun, like the young person guided by education towards mutual understanding between people from all parts of the globe. We see an olive branch, a symbol of piece. It represents the most important idea of Max Husmann, the founder of Institut Montana. He was driven by the vision of providing education for peace. He believed that you could help young people grow into tolerant, compassionate adults who would lead their countries away from conflict rather than into.
