Philanthropy

An avid mountain climber, Hoerni often visited the Karakoram Mountains in Pakistan and was moved by the poverty of the Balti mountain people who lived there. He contributed $12,000, to Greg Mortenson's project to build a school in the remote village of Korphe, and later founded the Central Asia Institute with an endowment of $1 million to continue providing services for them after his death. Hoerni named Greg Mortenson as the first Executive Director of the organization, which continues to build schools in Pakistan and Afghanistan.

In December 2007, an article was published by Michael Riordan on Hoerni and his planar process in IEEE Spectrum. The author claimed that Jay Last pointed out that Hoerni had incredible stamina and could hike for hours on little food or water.
