Laurent de Kalbermatten
Laurent was 18 years old when he became the first swiss champion of hanggliding in 1974. Since that time he got strongly involved in the conception and practice of all kind of flying machines. After completing his master in economy at Lausanne University, Laurent worked as a private banker for some years. Always passionate about flying, he passed his private pilote license in airplane and helicopter. In the 80’s, he decided to change his way of life and founded the company « Ailes de K>> with which he manufactured the first industrial paraglider « la Randonneuse » in partnership with Édouard Kessi. The paragliers Ailde K were distributed worldwide. This is the reason why Laurent is considered the father of the paragliding today. In 1999, he invented a new concept of wing, by marrying an inflated paraglider wing to a horizontal mast. The « Woopy wing » was born. Until today, it still flies as hangglider, skiglider, ultralight aircraft and even as unmanned aircraft. More recently, two years ago Laurent and Edouard Kessi joined forces again and by sharing their respective flying and sailing competences tested the « Woopy wing » vertically on a yacht. The new concept was a success and led to the birth of the IWS.
