Geri Winkler
In the 1990s he ascended Popocatepetl in Mexico and Muztagh Ata (7546 m) in China. In the summer of 2001, he climbed Elbrus in Russia, the highest mountain in Europe. In the winter of 2002 and 2003, Winkler climbed Aconcagua in Argentina, the tallest mountain in South America.
Omar Samra
On 1 February 2011, Samra became the first Arab in history to climb the highest mountain in South American (Argentina) Aconcagua solo; alone and unsupported. Samra began the climb on 20 January, and when the Egyptian revolution broke out on the 25th he was completely unaware of the events in the middle of nowhere. On the 28th, Samra tried to get in touch with family and realized all phones were down. When he finally managed to go online via satellite he realized what had happened. Torn between heading back to Tahrir Square or continuing up the mountain he was already three quarters of the way up, Samra decided to keep on climbing and on 1 February 2011 he raised the Egyptian flag on the highest mountain in the world outside of the Himalayas with the words 'Masr Lel Sha3b' written on the flag (translation: Egypt is for its people).
