Boyce Greer, a Fidelity Investments executive and avid outdoorsman, was killed in a kayaking accident in Idaho this weekend.

Greer, 55, was head of vice-chairman of Pyramis Global Advisors, the institutional investment arm of Fidelity Investments. He lived in Amherst, N.H., with his family.

Greer was kayaking on the Payette River in Banks, Idaho, when the fatal accident occured, the Boise County Sheriff's Office told The Union Leader.

All is known is that Greer was pronounced dead at the scene. No further details of the incident have been released.

The Union Leader reports that Greer was nicknamed "paddler super banker" in reference to his dual loves of investing and water sports.

Greer was the leading investor and owner in Liquidlogic/Legacy Paddlesports LLC, a company that makes kayaking gear.

Greer and his wife Ann were active in the water sporting community and were known to host fundraising parties at their home.

Readers of the local newspaper posted tributes to Greer in the comment section of the news story announcing his death.

One said: "A great loss to everyone who knew him. Whether in the office or on the rapids, when he gave advice you took it."

"Boyce & Ann were always very welcoming to everyone, and always supported American Whitewater in every way they could," another said. "We lost a wonderful human being."

"The entire Fidelity family is deeply saddened and will greatly miss him," Vincent Loporchio, a spokesman for Boston- based Fidelity, told Bloomberg News. "Boyce was more than just an accomplished business leader. He was an admired and greatly respected manager, colleague and friend."

Greer graduated cum laude from Harvard College in Cambridge, Massachusetts, in 1978 with an undergraduate degree in government. His graduate degrees in public policy were also from Harvard.
