Alan Neidlinger Hall, a resident of Hillhouse, Bath, Maine, formerly of Hopkinton, N.H., and for many years a teacher and administrator at St. Paul’s School, Concord, N.H., died peacefully on Aug. 22, 2015, at the age of 89. He was born on June 10, 1926, in Orange, N.J., the son of Helen Isabel Neidlinger Hall and Edwin Martin Hall.

His early education was in the East Orange, N. J, public schools and later at Willington School in Putney, England, where he lived from 1936 to 1939. He graduated from Woodrow Wilson High School, Washington, D.C., in 1942, and from Deerfield (Mass.) Academy in 1943. He matriculated at Dartmouth College in June 1943 with the class of 1947, but was drafted into the U.S. Navy in July 1944 in Newark, N.J. He attended recruit training and radio school at the U.S. Naval Training Center, Bainbridge, Md., and served aboard the destroyer tender U.S.S. Denebola (AD-12) in the Atlantic and Pacific and aboard the patrol craft U.S.S. PC-788 in the Pacific. In June 1946 he was discharged from the Navy as a Radioman Third Class.

Returning to Dartmouth in the fall of 1946, he majored in English and graduated cum laude. He was a member of the 1947 Dartmouth Mountaineering Club team climbing in the Wyoming Wind River Range; he also climbed in the Tetons and in Idaho.

He started his 43-year teaching career in the fall of 1949 at Williston Academy, Easthampton, Mass. In 1950 he married Margaret Hyde “Merry” Gilpin of West Chester, Pa., a 1949 economics honors graduate of Mount Holyoke College; they met skiing at Stowe, Vermont, in 1947. She died of cancer in 2003.

In the fall of 1952 he joined the faculty of St. Paul’s School to teach English, retiring from the classroom in 1992. During that period he taught from the 8th grade (Second Form) through the 12th grade (Sixth Form) and Advanced Placement classes, served twice as head of the English department and twice as the director of the Advanced Studies Program, St. Paul’s summer school for talented New Hampshire high school juniors. He also taught English at the ASP for many years, was involved in its fundraising, and edited its newsletter.

In addition to his teaching, he was, over the years, Director of Activities, Director of Studies and College Advisor, Director of Publications, and Head of the Upper School, the Sixth Form (seniors) dormitory. For 12 years he edited the school’s alumni magazine, Alumni Horae, and served twice as acting Executive Director of the St. Paul’s School Alumni Association.

In retirement he continued as a consultant for and contributor to the school’s publications. He coached the SPS ski team, coached club and junior varsity soccer, and served in the state as a high school boys lacrosse referee.

Mr. Hall was a trustee emeritus of Wilbraham and Monson Academy in Massachusetts, and in the 1970s he served on committees at Deerfield Academy and Middlesex School to study the transition to co-education. He was a member of the New England Association of Schools and Colleges evaluation teams for Salisbury (Conn.) School, Governor Dummer Academy, Byfield, Mass., and Roxbury Hill School in Boston.

He was the editor of Conrad and the Congo published by the Independent School Press in 1972. His poetry appeared in many “little magazines” and in Good Housekeeping in the ‘50s. His articles appeared in such varied magazines as The Classical Journal and Skiing.

After retiring from St. Paul’s School to Hopkinton, N.H., he was for many years a volunteer in the Emergency Department of Concord Hospital, a docent at the Museum of New Hampshire History in Concord, and a board member of the Hopkinton Historical Society, formerly the New Hampshire Antiquarian Society.

For 40 years Mr. Hall and his family summered on the rocky banks of the Damariscotta River in South Bristol, Maine, in a house he helped to build. After 56 years in the Concord/ Hopkinton area, Mr. Hall moved to Thornton Oaks, a retirement community in Brunswick, Maine, in 2009, and to Hillhouse in Bath in November of 2014.

He is survived by three sons: Christopher Gilpin Hall of Woolwich, Me., his wife, Sarah Hildreth Robey Hall, and their children Hannah Alice Gilpin Hall of Westport, Conn. and Eben Hazard Robey Hall of New York City; Newell Neidlinger Hall of Milton, Mass., his wife Jane Gallagher Hall, and their children Chase Neidlinger Hall, Megan Gallagher Hall and Kyle Neuhoff Hall all of Milton; and Benjamin Kellock Hall of Milton, Mass., his wife Kelly Walsh Hall, and their children Henry Gilpin Hall and Duncan Walsh Hall.
