Dorothy Thompson Arrison, of Darien, died Monday, Jan. 10, after a long and courageous battle with non-Hodgkin lymphoma, at the Rosenthal Hospice Residence in Stamford, surrounded by her family.

Born June 27, 1925, in Neenah, Wisc., "Dottie" was the only child of Veneta Beck Thompson and Oscar Theodore Thompson.

During World War II she attended Lawrence College in Appleton, Wisc. After the war she transferred to Wellesley College, graduating in 1947 as a Wellesley Scholar and a member of the Zeta Alpha Society with a major in zoology and a minor in art.

She met her husband, Bob, during her senior year in college and they married in 1949. The family moved to Darien in 1970.

She was very involved in church and volunteer activities. She was a member of the Noroton Presbyterian Church, where she served as a deacon, an elder and a Stephen Minister. Her volunteer activities included work with the Junior League, the Darien Community Association, and Person-to-Person, for which she served as a board member. She was also actively involved with the Noroton Yacht Club, the Country Club of Darien, Wee Burn Country Club and with an informal women's group, the Go Girls.

She enjoyed sailing, locally and on the Maine coast, playing bridge, playing tennis, drawing and painting, and solving crosswords and cryptograms.

Survivors include four children, Robert Thompson "Tom" Arrison of Providence, R.I., John Gilmour Arrison of Belfast, Maine, Janet Arrison Spedden, and James Alexander Arrison; four sons- and daughters-in-law; six grandchildren; two brothers-in-law; and six nieces and nephews.

She was predeceased by her husband of 55 years, Robert Alexander Arrison Jr., and by an infant daughter, Jane Arrison.
