Who became the Chief Scout of the Scouting Association in 2009?

Edward Michael Grylls (born 7 June 1974), better known as Bear Grylls, is a British former SAS serviceman, survival instructor, and honorary lieutenant-colonel, and, outside his military career, an adventurer, writer, television presenter and businessman. He is widely known for his television series "Man vs. Wild" (2006–2011), originally titled "Born Survivor: Bear Grylls" for the United Kingdom release.

Grylls is also involved in a number of wilderness survival television series in the UK and US. In July 2009, Grylls was appointed the youngest-ever Chief Scout of the United Kingdom and Overseas Territories at age 35, a post he has held for a second term since 2015.

After leaving school, Grylls briefly hiked in the Himalayan mountains of Sikkim and West Bengal. From 1994–1997, he served in the British Army reserves with 21 SAS as a trooper trained in unarmed combat, desert and winter warfare, survival, climbing, parachuting, and explosives. Becoming a survival instructor, he was twice posted to North Africa. His time in the SAS ended as the result of a free fall parachuting accident the year before in Kenya, when his parachute failed to open, breaking three vertebrae.

In 2004, Grylls was awarded the honorary rank of lieutenant commander in the Royal Naval Reserve; and in 2013 he was awarded the honorary rank of lieutenant colonel in the Royal Marines Reserve.
