British-Nepali climber Nirmal Purja, who died in the Broad Peak avalanche, was one of the most recognised figures in mountaineering today. He held multiple records, but his most famous feat was in 2019, when he climbed the world's 14 tallest peaks in just over six months - setting a record at the time for the fastest anyone had scaled all 14 mountains. Purja, also known as Nims Dai, was among 10 climbers who went missing after an avalanche on Thursday on Broad Peak, an 8,047m (26,400ft) mountain in Pakistan-administered Gilgit-Baltistan. Later his company Elite Expeditions said he was one of 10 people killed in the avalanche. Here's what to know about Purja.
