SOUTHWEST HARBOR – Cecil S. Peterson, 78, died May 1, 2008, at an Ellsworth health care facility after a short illness. She was born Jan. 21, 1930, in St. Louis, the daughter of C. Alvin and Elizabeth (Bradshaw) Snodgras Jr. Cecil graduated from St. Mary’s Institute, St. Louis and Pembroke College, Providence, R.I., with a Bachelor of Science degree in engineering in 1951. She was the first female to graduate with an engineering degree. After graduation she worked for General Dynamics, St. Louis, designing airplanes. She married her beloved husband, John O. Peterson on Valentines Day, Feb. 14, 1953, at her home in St. Louis. Cecil traveled extensively both with her beloved husband and alone after his passing. When China opened to U.S. tourism in the early 1980s, she was there. Antarctica called, and she answered. Machu Picchu in Peru beckoned and she went. The Northwest Passage had to be conquered and she did. Tibet had mountains to climb, so she did, only a few years ago. She lived in England with her beloved husband, John, for three years and traveled throughout Europe. She was very proud of having every page in her passport filled. Cecil enjoyed walks in the woods with her dog and hiking mountains. She enjoyed needlework of all types, sewing, knitting, needlepoint, rug making and cross-stitch. She loved the water and anything she could do in it, sailing, rowing and power yachting. She liked to live life to the fullest, so she volunteered her time and knowledge. She work-ed for many years doing income taxes and was an enrolled agent. She volunteered as a tax preparer with AARP Tax-Aide Program and IRS VITA Program. She enjoyed the friendships that developed with her many tax clients. She was a keen bridge player, traveling throughout New England and Canada for tournaments. She delivered for Meals on Wheels, Southwest Harbor, until her illness. She spent much of her time helping out at Southwest Harbor Library, volunteering with their fundraisers. She kept active with her Footloose Friends each week hiking. She will be missed by her family and many friends. She is survived by two sons, C. Andrew and wife, Teri Peterson, of Lancaster, Pa., and Geoffrey W. Peterson of Scotts Valley, Calif.; one very special grandson, Joshua Peterson and fiance, Laura Wells, of Lancaster, Pa.; and two nephews in Missouri and New Jersey. She was predeceased by her husband, John O. Peterson; and her sister, Sally S. Clamp of St. Louis. Friends may call 4-6 p.m. Friday, May 9, at Jordan-Fernald Funeral Home, 1139 Main St., Mount Desert, where funeral services will be held 10 a.m. Saturday, May 10.
