BAR HARBOR — The Rev. James Gower, a co-founder of the College of the Atlantic in Maine, has died at 90.

The peace activist joined businessman Les Brewer, a former football teammate at Bar Harbor High School, to found the college in 1969. The college, which has an environmental focus, has only one major, human ecology. The first classes were held in 1972.

The college says Gower died early Monday in assisted living in Bar Harbor.

Bill Slavick, a peace activist who ran for the U.S. Senate in 2006, said Gower was active in Pax Christi, the Roman Catholic peace movement.

As a priest, Gower served in Waterville, where he was well known, as well as other locations including the University of Maine, where he was chaplain.
