Scarborough- Arthur Hansen Stolpestad, 69, of South Portland, died on Sunday, July 24, 2011 at the Gosnell Hospice House in Scarborough after a valiant battle with an aggressive form of Prostate Cancer. He was born in Medford, MA on October 7, 1941, the son of Birger Hansen Stolpestad of Oslo, Norway, and Martha Hille Danielsen Stolpestad of Mandal, Norway. He graduated from Lynn English High School, Lynn, MA in 1959, where he met his wife of 47 years, Bonnie Jean Harthan, '59. Arthur received a BS in Mechanical Engineering from the General Electric-Tufts Apprentice program in 1965 and an MBA from New Hampshire College in 1983. His purchasing and logistics career in management included General Electric in Lynn, MA, Bath Iron Works, LL Bean, State of Maine, and Procurement Technical Assistance Program in Lewiston. He was involved with Prostate Cancer Awareness, and his well-researched documentation of his personal journey identified a lengthy familial pattern of the cancer that is spurring family in the US and Norway to take earlier preventative measures. Arthur loved geneology, classic wooden boats, marksmanship, and passed on to family and friends alike his gigantic curiosity for the natural world and deep love for the ocean.
