Anne O. Mueller, 98, of Camden, died Thursday, Nov. 19, 2009, at Penobscot Bay Medical Center in Rockport.

Born in Cleveland, Ohio, on March 19, 1911, she was the daughter of Anton E. and Anna (Kordan) Ospeck.

The eldest of five children, she was raised on a farm in Salem, Ohio. Anne attended local schools, graduating from Salem High School in 1929. She attended Mount Union College, where she earned a B.A. with honors in 1932.

In 1949 she received an M.S. degree from the University of Tennessee.

After college Anne taught school in Salem from 1932 to 1936. She then moved to New York City to pursue a career in medical research. After spending the summer of 1936 working for City Lab at New York Department of Public Health, she then worked as a bacteriologist at Lederle Laboratories in Pearl River, N.Y., from 1936 to 1943. She co-authored scientific articles on pertussis toxin-antitoxin. During this time she also studied medicine at the College of Physicians and Surgeons at Columbia University.

From 1943 to 1945 Anne worked as a bacteriologist at Wyeth Laboratories’ subsidiary, S.M.A. Corporation, a pharmaceutical firm specializing in innovative infant formulas in Chagrin Falls, Ohio. She returned to New York City and from 1945 to 1946 worked as a bacteriologist at Vanderbilt Clinic, Department of Dermatology, Columbia University College of Physicians and Surgeons. She assisted Dr. A. Benson Cannon with his research on increasing the retention of penicillin in the blood, contributing to the newly developed penicillin therapy – the antibiotic that was to save countless lives.

On June 1, 1946, Anne married Dr. George Peter Mueller of Lincoln, Neb., at St. Paul Church in Salem, Ohio. He was a professor of organic chemistry and a research chemist, so they moved several times throughout their married life, residing in Chestnut Hill, Pa., Knoxville, Tenn., and Park Ridge, Ill. In 1962 Dr. and Mrs. Mueller moved to Camden, where Dr. Mueller was director of research at Marine Colloids in Rockland. They were married for 45 years, until his death in 1991.

Anne began a new career when she became a social worker for the Maine Department of Health and Welfare from 1966 to 1981. She loved being a child social worker and specialized in adoptions. She often maintained contact with children who had been under her care, following them through their education and into their adult lives and taking pride in their success.

Throughout her life, Anne was a tireless and active supporter of civic causes. She was a Girl Scout troop leader in Camden for many years. She volunteered at Penobscot Bay Medical Center, St. Bernard’s Soup Kitchen, Camden-Rockport Animal Rescue League, Center for Maine Contemporary Art, and the Retired Senior Volunteer Program. She was also a member of the New England Historic Genealogical Society, American Association of University Women, Senior College, Farnsworth Art Museum, Camden Garden Club, and Camden Yacht Club.

She was a communicant of Our Lady of Good Hope Catholic Church in Camden.

Anne was an enthusiastic traveler, frequently visiting relatives in Slovenia, visiting England and France on art history tours, and the Mediterranean on archaeology tours. At the age of 90 she travelled to China, and in recent years she spent Christmases in Paris.

She was proud of her Slovenian heritage and spoke the language fluently. She spent decades researching her family’s genealogy and keeping the many branches of the family, located in the United States, France, Slovenia, Argentina, and Venezuela, connected with one another. She was the acknowledged matriarch of her extensive family.

She was an accomplished cook, a passionate gardener, an avid reader, a gifted artist, and a life-long patron of the ballet, opera, and classical music.

She was a friend to all animals, including the generations of raccoons she trained to eat out of her hand. Over the years she shared her home with a succession of cats, most recently her beloved 20-year old Siamese cat, Simon.

Anne was an amazing and inspiring woman. She exhibited a remarkable vitality and zest for life that awed everyone who knew her. She will be remembered for her determined optimism, her keen intellect and inquiring mind, her sense of humor and her distinctive laugh. She touched many lives with her caring and compassion and incredible strength of spirit.

Phelps of Pueblo, Colo., and Margaret P. Ospeck of Salem, Ohio; her former son-in-law, Simon Bendall of London, England; several nieces, nephews and cousins and their families.
