Under Dr. Chamberlain's leadership, full-time enrollment more than doubled from 3,529 in fall 1968 to 8,788 in fall 1984. Nine buildings were built or purchased, five more were renovated, and on-campus beds increased from 900 to 2,700.
Dr. Chamberlain supervised development of three new academic divisions and encouraged the start of a dozen new major programs, many minors, and two educational specialist programs.
Under his guidance, minority student enrollment grew, as did the number of women and minority faculty.
"He had an open-door policy, which I took full advantage," retired lawyer Amanda Koon wrote on a Glassboro State/Rowan black alumni Facebook page. "A fair man."
Dr. Chamberlain is also credited with steering the college through the turbulent 1970s and early 1980s, managing to avoid the chaos and disturbances that played out on many other campuses.
"He was a steady hand through that great unrest," said Robert Zazzali, now university vice president and the current president's chief of staff.
Rather than suppressing dissent, Dr. Chamberlain would encourage open discussion of ideas, including divergent ones, said Zazzali, a student when Dr. Chamberlain came to Glassboro. He went on to become an employee and a friend.
The best interest of the students was always foremost to Dr. Chamberlain, and Zazzali said it was fitting the university's student center was named in his honor in 2006.
"He was just a very warm, cordial, and sweet man," Zazzali said.
And he stayed committed to Rowan. After he left the presidency, he stayed and taught chemistry until June 2000. He continued to attend commencements and other school events.
"We tried to attend as many events as he could," said his wife, Barbara.
"He loved the community," she said. "He loved that there was so much room for growth."
Dr. Chamberlain was born in Rhode Island, and his family moved to the Pittsburgh area when he was a boy, she said.
He earned a bachelor's degree from Franklin and Marshall College and a doctorate in chemistry from the University of Illinois.
He was a volunteer firefighter in Glassboro, as well as an active member of the Friends of Gettysburg National Park and St. Mark's at the Crossing Church. He was also a member of the American Chemical Society.
In addition to his wife, Dr. Chamberlain is survived by five children, 10 grandchildren, and five great-granddaughters.
A viewing will be Wednesday, April 2, from 6 to 8 p.m. at the Norton Funeral Home, 1232 S. Black Horse Pike, Williamstown. The funeral service and burial will be private.
