Ivan Kristoff
Ivan Kristoff (born Ivan Hristov, June 27, 1968) is an aviator, rescue worker, and rope access expert in vertical and aerial operations. He has developed various solutions to improve the safety of vertical and aerial rope access manoeuvres. His work in vertical and remote access in extreme conditions and heights has contributed to the development and improvement of safety standards.
==Early life==
At the age of 15 Kristoff made his own improvised climbing tools and started rock climbing and rappelling. He later joined caving and climbing clubs, including the Speleo Club. During caving activities in the western part of Bulgaria, he discovered new extensions of the Cave "Goliamata Balabanova". The club mapped the new areas and extended the explored area of the cave by more than 4,500 metres.
He started solo climbing〔http://ivankristoff.com/free-solo-climber/〕 and joined an alpine club with the goal of escaping the communist regime.〔http://i41.tinypic.com/a4y1oj.jpg Toronto Sun〕
In 1987–1989, Kristoff was conscripted into the Bulgarian Army. Upon his discharge, he joined a national expedition and climbed Mount Elbrus () in the Caucasus, Georgia.
