Alan John McClelland, 87, died of natural causes May 8, 2010, at Penobscot Bay Medical Center in Rockport. He was born Jan. 15, 1923, in Long Branch, N.J., the only child of Harold Mark McClelland and Doris Cruger McClelland (Mellersh). Alan attended St. Albans School for boys in Washington, D.C., graduating in 1943. He was inducted into the Army Air Force in December 1942, where he was trained as a radar mechanic. His assignments as a ground control approach radar technician included Manila, the Philippines, and Osaka, Japan. After his discharge from the Army in 1946, Alan enrolled at Virginia Polytechnic Institute in Blacksburg, Va.

On June 25, 1949, he married Eleanor Virginia Webbley in Watertown, Mass. After receiving his bachelor of science in electrical engineering degree in 1950, Alan was offered a job at Gilfillan Brothers in Los Angeles. There, he worked as an electronic engineering manager in the development of electronic countermeasures equipment. Alan and Eleanor’s son, John Alan McClelland, was born in 1952 in Pasadena, Calif. In 1961, Alan accepted a position with the Philco Corporation (renamed Ford Aerospace) in Palo Alto, Calif., as an aerospace engineering manager. Alan’s team was responsible for preparing a successful proposal to design and construct the Mission Control Center for NASA. In 1963, Alan and his family relocated to Houston, Texas, where the Manned Spacecraft Center was under construction. His division continued to support the operation and maintenance of Mission Control Center through the historic early years of the manned spaceflight program. Following retirement in 1985, Alan and Eleanor moved to their beloved Camden, where they made many good friends. In 2009, they celebrated their 60th wedding anniversary.

In addition to his fascination with electronics and aerospace, Alan had a lifelong passion for photography, and the beautiful land and seascapes of coastal Maine provided him with much inspiration. During his retirement, Alan volunteered with the Camden Rockport Animal Rescue League, served as a board member of Northeast Historic Film in Bucksport, and served as an avid volunteer with the Owls Head Transportation Museum. Alan and Eleanor became seasoned world travelers in their retirement, completing trips to the Antarctic, the Arctic, Africa, Europe, Alaska, Canada, Australia and New Zealand.

Alan is survived by his wife, Eleanor, his son, John, and his daughter-in-law, Ann.

A celebration of life for family and friends will be held later this summer on a date to be announced. In lieu of flowers, friends are encouraged to make a contribution to their favorite charity in memory of Alan.

Arrangements are with the Long Funeral Home & Cremation Service, 9 Mountain St. in Camden.
