(Bloomberg) -- Ballentine Partners is a wealth management firm with roots in an unusual institution: a summer camp.

Camp Kehonka, founded in 1902, brought girls to the southeast shore of Lake Winnipesaukee in New Hampshire to swim and make handicrafts. In 1910, a young man named A.C. Ballentine applied for a job there. No position was open, but the camp’s founder invited him to visit for a week. Ballentine ended up staying for the rest of his life, becoming owner and director of the camp. “He went as a guest and he never left,” his son Roy Ballentine says.
