Pippa Middleton Scales Matterhorn in Honor of Fiance's Brother

— -- Pippa Middleton and her brother James successfully reached the summit of the Matterhorn, a 14,692 foot peak in Switzerland, on Saturday. Pippa scaled the mountain in honor of her fiancé James Matthews' brother Michael.

Michael, who became the youngest Brit to reach the summit of Mt Everest, died in 1999 while descending the mountain when he was just 22.

Pippa told The Mail on Sunday she was "humbled" to complete the climb. Pippa and her brother James were raising money on behalf of the Michael Matthews foundation, which builds schools in remote parts of the world.

Pippa told The Mail on Sunday "It was humbling to have been able to climb one of the world's most beautiful mountains and raise money for a charity created in memory of an extraordinary young man who lost his life on another peak.

"Although I have raised money in the past for the Michael Matthews Foundation, it has now become even more important to me and my family."

"Although neither I nor my brother ever met Michael, we both share his spirit and passion for the mountains. We made this climb knowing he would have been there nudging us on, and we are honored to be supporting his memory."

Her fiancé is said to be haunted by the loss of his brother, and did not make the climb but gave Pippa and James his complete support. James has competed with Pippa in numerous other endurance challenges to benefit the foundation named in Michael's honor.
