Rescue Effort Abandoned for Boston Business Man

iStockphoto/Thinkstock(NEW YORK) -- The rescue of a Boston entrepreneur who fell into a deep crevasse while hiking in New Hampshire mountains has been abandoned.

Norman Priebatsch, 67, was on a hike with his son and two others on Sunday afternoon when he lost his footing on the White Mountains and fell into the crevasse.

His companions called for help after hearing no response from Priebatsch.

Efforts were called off Tuesday because of increasingly treacherous conditions on the mountain and hikers were being told to avoid the area.

Priebatsch’s family has scheduled a service for the missing man on Thursday at Temple Emmanuel in Newton, ABC News confirmed.

Priebatsch, a graduate of 1972 Harvard Business School, co-founded a biochemical company called Adeptrix.  He also helped start a project called Tinnix, which used evaluation trials to determine if an iPhone app can evaluate the use of notched music as therapy to alleviate tinnitus.

According to his Tinnix biography, he enjoyed skiing, windsurfing, long distance running and hiking.  His wife Suzanne is an investment advisor at Smith Barney and his daughter Danielle works at Google in California. Priebatsch’s son Sam founded the social networking site SCVNGR.
